Cardio-Physiological and Anthropometric Profile of Elite International Handball Players from Top Ranking Macedonian Teams / Perfil Cardiofisiológico y Antropométrico de Jugadores Internacionales de Balonmano de Élite de Equipos Macedonios de Primer Nivel

SUMMARY: Monitoring of body composition and cardiophysiological parameters are main part of the general health status of handball players and significant indicators of their physical fitness. The assessment of body components, especially skeletal muscle mass and body fat mass are important because of their influence on sport performance. The aim of this study is to determine the body composition and cardiophysiological characteristics of elite handball players from Republic of North Macedonia. 27 male HB players from two top ranking teams from RNM were tested ergometrically with Bruce protocol for determination of maximal oxygen consumption; body analysis was made with bioelectrical impedance analyzer, InBody 720. Anthropometric parameters were as follows: mean height was 190.4±7.8 cm and weight 96.3±15.5 kg, skeletal muscle mass (SMM)=47.11±6.69 kg; BMI=26.38±3.1; BF%=15.04±6.01 and WHR=0.9±1.8. The result of ergometrical test produce mean VO2 max=43.92 ml/kg/min which is 100.46 % of reference value. The body composition of elite international handball players from the top handball teams in Republic of North Macedonia showed similar body components as other European handball players. The obesity diagnose parameters were negatively associated with exercise time and maximal oxygen consumption.

Los parámetros antropométricos fueron los siguientes: talla media 190,4±7,8 cm y peso 96,3±15,5 kg, masa músculo esquelética (SMM)=47,11±6,69 kg; IMC=26,38±3,1; %GC=15,04±6,01 y RCC=0,9±1,8. El resultado de la prueba ergométrica produce un VO2 máximo medio = 43,92 ml/kg/ min, que es el 100,46 % del valor de referencia. La composición corporal de los jugadores de balonmano internacionales de élite de los mejores equipos de balonmano de la República de Macedonia del Norte mostró componentes corporales similares a los de otros jugadores de balonmano europeos. Los parámetros diagnósticos de obesidad se asociaron negativamente con el tiempo de ejercicio y el consumo máximo de oxígeno.

Tokyo 2021 Olympic Water Polo Champions and Their Anthropometric Characteristics and Body Composition Compared to Other Players / Campeones Olímpicos de Waterpolo de Tokio 2021 y sus Características Antropométricas y Composición Corporal en Comparación con Otros Jugadores

SUMMARY: The Olympic Games always offer great interest when it comes to water polo. Currently, many selections have an approximate quality and details determine who will win. Prior to the tournament the authors wanted to verify body composition and anthropometric characteristics of players of the three national teams, Serbia, the United States of America (USA) and Montenegro. The purpose of this research was to determine the differences in body composition and anthropometric characteristics between the water polo players of the national team of Serbia and Olympic champion in Tokyo 2021, the national team of USA which took sixth place and the national team of Montenegro, which took the eighth place. Body mass index, fat percentage and muscle mass (body composition variables) were evaluated by Bioelectric Impedance type MC-980 and body height, body weight, triceps skinfold, biceps skinfold, skinfold of the back, abdominal skinfold, upper leg skinfold, lower leg skinfold (other anthropometric characteristics) were evaluated by an anthropometer and a calliper. ANOVA showed that there was a statistically significant difference in fat percentage. The LSD post hoc test showed statistically significant differences between the water polo players of the Montenegrin national team (13.33 %) compared to the water polo players of the USA national team (16.67 %). It can be stated that water polo players from Montenegro had a statistically significantly lower fat percentage than water polo players from the USA and a lower level of fat than water polo players from Serbia, though this was not statistically significant. Although the fat percentage is a disruptive factor with athletes, it had no effect on the result at the Olympic Games in Tokyo, because Serbia eventually won the gold medal, the USA obtained sixth place, and Montenegro eighth place. It means that some other abilities influenced the results at the Tokyo Olympics in water polo, for example tactical, physical, psychological, technical... which is to be shown by some other research.

Los Juegos Olímpicos siempre ofrecen un gran interés en lo que respecta al waterpolo. Actualmente, muchas selecciones tienen una calidad aproximada y los detalles determinan quién ganará. Antes del torneo, los autores deseaban comprobar la composición corporal y las características antropométricas de los jugadores de las tres selecciones nacionales: Serbia, Estados Unidos (EE.UU.) y Montenegro, que siempre tienen las mayores ambiciones en las grandes competiciones. El propósito de esta investigación fue determinar las diferencias en composición corporal y características antropométricas entre los jugadores de waterpolo de la selección nacional de Serbia, que fue campeona olímpica en Tokio 2021, la selección nacional de Estados Unidos que ocupó el sexto lugar y la selección nacional de Montenegro, que acabó octavo. El índice de masa corporal, el porcentaje de grasa y la masa muscular (variables de composición corporal) se evaluaron mediante Impedancia Bioeléctrica tipo MC-980 y la altura corporal, el peso corporal, el pliegue del tríceps, el pliegue del bíceps, el pliegue de la espalda, el pliegue abdominal, el pliegue de la parte superior de la pierna y la parte inferior de la pierna. Los pliegues cutáneos (otras características antropométricas) fueron evaluados mediante un antropómetro y un calibrador. ANOVA mostró que había una diferencia estadísticamente significativa en el porcentaje de grasa. La prueba post hoc de LSD mostró diferencias estadísticamente significativas entre los jugadores de waterpolo de la selección nacional de Montenegro (13,33 %) en comparación con los jugadores de waterpolo de la selección de Estados Unidos (16,67 %). Se puede afirmar que los jugadores de waterpolo de Montenegro tenían un porcentaje de grasa estadísticamente significativamente menor que los jugadores de waterpolo de EE. UU. y un nivel de grasa más bajo que los jugadores de waterpolo de Serbia, lo que no es estadísticamente significativo. Aunque el porcentaje de grasa es un factor perturbador para los atletas, no tuvo ningún efecto en el resultado de los Juegos Olímpicos de Tokio, ya que al final Serbia ganó la medalla de oro, Estados Unidos quedó en sexto lugar y Montenegro en el octavo lugar. Esto significa que en los resultados de los Juegos Olímpicos de Tokio en el waterpolo influyeron otras habilidades, por ejemplo tácticas, físicas, psicológicas y técnicas, tal como lo demostrarán investigaciones a futuro.

Se resaltaron las características del tenis de mesa como deporte, así como las lesiones que se presentan en el mismo. Se indagó acerca de las bases teóricas de los músculos estabilizadores que son aquellos que permiten fijar una articulación para poner ciertos grupos musculares en movimiento. Los tenimesistas categoría sub 13 de La Habana carecen de un instrumento metodológico que sustente el entrenamiento de la resistencia a la fuerza de los músculos estabilizadores, por lo que se propuso como objetivo de esta investigación evaluar la resistencia a la fuerza de los músculos estabilizadores de los tenimesistas categoría sub 13 de La Habana. Se diseñó el instrumento eval-lumbar tennis que permitió valorar el nivel de resistencia a la fuerza de los músculos estabilizadores de la muestra seleccionada. Como resultados, el 100 % de la muestra presentó una resistencia a la fuerza deficiente, donde se encontraron débiles los siguientes músculos: recto abdominal, oblicuo abdominal, multífidos, cuadrado lumbar, intertransverso, serrato anterior, erectores espinales y deltoides en su porción lateral y frontal.

O trabalho que se apresenta assenta num estudo descritivo, de natureza qualitativa e quantitativa; Para isso, foram aplicados métodos teóricos como indutivo-dedutivo e analítico-sintético, métodos empíricos como revisão documental, observação, levantamento e entrevista; além da medição para obtenção dos dados amostrais, a partir da aplicação dos testes. Foram destacadas as características do tênis de mesa enquanto esporte, bem como as lesões que nele ocorrem. Foram investigadas as bases teóricas dos músculos estabilizadores, que são aqueles que permitem fixar uma articulação para colocar em movimento determinados grupos musculares. Os tenistas da categoria sub 13 de Havana carecem de um instrumento metodológico que apoie o treinamento de força resistida dos músculos estabilizadores, por isso o objetivo desta pesquisa foi avaliar a força resistiva dos músculos estabilizadores dos tenistas da categoria sub 13 de Havana. O instrumento de tênis eval-lombar foi projetado para avaliar o nível de resistência à força dos músculos estabilizadores da amostra selecionada. Como resultados, 100% da amostra apresentou resistência à força deficiente, onde se encontravam fracos os seguintes músculos: reto abdominal, oblíquo abdominal, multífido, quadrado lombar, intertransverso, serrátil anterior, eretores da coluna vertebral e deltóides em sua porção lateral e frontal.

The work that is presented is based on a descriptive study, of a qualitative and quantitative nature; for this, theoretical methods such as inductive-deductive and analytical-synthetic, as well as empirical methods such as documentary review, observation, survey, interview and the measurement to obtain the sample data, from the application of the tests were applied. The characteristics of table tennis as a sport were highlighted, as well as the injuries that occur in it. The theoretical bases of the stabilizing muscles were studied, which are those that allow fixing a joint to put certain muscle groups in motion. The sub 13 category tennis players in Havana lack a methodological instrument that supports the strength endurance training of the stabilizer muscles, so the objective of this research was to evaluate the strength endurance of the stabilizer muscles of the sub 13 category tennis players from Havana. The eval -lumbar tennis instrument was designed to assess the level of endurance to strength of the stabilizing muscles of the selected sample. As a result, 100 % of the sample presented a deficient endurance to strength, where the following muscles were found to be weak: rectus abdominis, oblique abdominis, multifidus, quadratus lumborum, intertransversus, serratus anterior, spinal erectors and deltoids in its lateral portion and frontal.

Anthropometric Characteristics and Body Composition of Elite Youth Male Basketball Players - Participants of Junior Euroleague / Características Antropométricas y Composición Corporal de Jugadores de Baloncesto Masculino Juveniles de Élite - Participantes de Junior Euroleague

SUMMARY: The aim of this research was to determine the differences among the junior basketball players of the BC Partizan and BC Buducnost Voli, in terms of their anthropometric characteristics and body composition. A sample of 22 subjects was divided into two sub-samples. The first sub-sample of the subjects consisted of 11 players of the basketball team Partizan (Serbia), of the average age 17.18 ± 0.50, while the other sub-sample consisted of 11 players of basketball team Buducnost Voli (Montenegro), based on the average age of 17.28 ± 0.30. All players were tested in Podgorica, in a lasting period of two days, while they held international friendly tournament, just before the start of the national championships. Anthropometric characteristics in the body composition were evaluated by a battery of eleven variables: body height (cm), body weight (kg), triceps skinfold, back skinfold, biceps skinfold, abdominal skinfold, thighs skinfold, calf skinfold, body mass index (BMI), percentage of fat and muscle mass (kg). Differences in anthropometric characteristic and composition of the body of the male junior basketball players of two basketball teams were determined by using a discriminatory parametric procedure with t-test for small independent samples. It was found that the basketball players of Partizan are taller and have a lower body mass. Also, there are significant statistical differences by seven: triceps skinfold, back skinfold, biceps skinfold, abdominal skinfold, calf skinfold, thigh skinfold and BMI.

El objetivo de esta investigación fue determinar las diferencias entre jugadores de baloncesto junior del BC Partizan y BC Buducnost Voli, en cuanto a sus características antropométricas y composición corporal. Una muestra de 22 sujetos se dividió en dos submuestras. La primera submuestra estuvo formada por 11 jugadores del equipo de baloncesto Partizan (Serbia), con una edad media de 17,18 ± 0,50, mientras que la otra estaba formada por 11 jugadores del equipo de baloncesto Buducnost Voli (Montenegro), cuya edad media era de 17,28 ± 0,30 años. Todos los jugadores fueron evaluados en Podgorica, en un período de dos días, mientras se realizaba un torneo amistoso internacional, precisamente antes del inicio de los campeonatos nacionales. Las características antropométricas en la composición corporal se evaluaron mediante una batería de once variables: altura corporal (cm), peso corporal (kg), pliegue cutáneo tríceps, pliegue cutáneo dorsal, pliegue cutáneo bicipital, pliegue cutáneo abdominal, pliegue cutáneo de muslos, pliegue cutáneo de pantorrillas, índice de masa corporal (IMC), porcentaje de grasa y masa muscular (kg). Se determinaron las diferencias en las características antropométricas y la composición del cuerpo de los jugadores juveniles masculinos de baloncesto de los dos equipos de baloncesto mediante un procedimiento paramétrico discriminatorio con prueba t para pequeñas muestras independientes. Se encontró que los jugadores de baloncesto del Partizan eran más altos y tenían una masa corporal más baja. Además, existían diferencias estadísticas significativas en los pliegue cutáneos del tríceps, de la espalda, del bíceps, abdominal, de la pantorrilla y del muslo además de diferencias en el IMC.

Digit ratio (2D:4D) and performance in non-elite male badminton players

Background: The second to fourth digit ratio (2D:4D ratio) is derived by dividing the length of the index finger (2D) by the length of the ring finger (4D). It has been considered as an index of how much the fetus is exposed to testosterone in utero. Research has suggested that high levels of testosterone are associated with low 2D:4D ratio. The relationship between 2D:4D ratio and physical performance is still an unexplored field in badminton players. Aims and Objectives: This study intends to assess the digit ratio 2D:4D in non-elite male badminton players in comparison to their sedentary controls. Materials and Methods: The study included 30 male badminton players in the age group of 19–23 years who were practicing badminton for more than 3 years and 30 age, body mass index-matched sedentary controls. The second and fourth finger measurements were taken from scanned printouts using Vernier calipers. Results: The 2D:4D ratio was significantly lower in the left hand of badminton players when compared to their controls (P = 0.0001). There was no significant difference in 2D:4D ratios of the right hand and 2D:4D (? r–l) between badminton players and controls. Conclusion: There was significant difference in the ratio of 2nd–4th digit between badminton players and controls in the left hand but not in the right hand. The reason for no difference in 2D:4D ratio and controls in the right hand could be due to the fact that badminton is a moderate intensity sport, and also, the study participants were non-elite players.

Morphological characteristics according to basketball playing positions / Características morfológicas según las posiciones de juego del baloncesto

SUMMARY: This paper aimed to investigate the morphological characteristics according to the positions of basketball players. In this work, a sample of 62 basketball players aged 16-17 years, whose body height was 177.31 ± 8.112 cm, while body mass of 72.44 ± 13.27 kg, were divided into five main positions of the basketball game: Organizer of the game (n=13), shooting guard (n=14), small forward (n=14), power forward(n=11) and center (n=10). Tested are from the clubs RTV-21, ProBasket-Pristina, M - Junior from Pristina of the male gender who are following the training program from Basketball. In this research, morphological space variables were applied (n=10). Based on the obtained results, very few significant values were presented in the morphological characteristics between the group of outside players (organizer of the game, small forward and power forward) who covered the 6.75-meter line. However, the group of interior players (power forward and centers) under the basket showed significant values in all morphological variables. In the end, it can be concluded that the results of this research will be able to contribute to a better definition of the morphological characteristics between the groups defined according to the players' positions.

Con base en los resultados obtenidos, se presentaron muy pocos valores significativos en las características morfológicas entre el grupo de jugadores externos (organizador del juego, alero y ala-pívot) que cubrieron la línea de 6,75 metros. Sin embargo, el grupo de jugadores interiores (pívot y pívot) bajo canasta mostró valores significativos en todas las variables morfológicas. Se puede concluir que los resultados de esta investigación podrán contribuir a una mejor definición de las características morfológicas entre los grupos definidos según las posiciones de los jugadores.

Effect of hip neuromuscular training on anterior cruciate ligament injury risk for female soccer players / 中国康复理论与实践

ObjectiveTo explore the effect of hip neuromuscular training on reducing the risk of anterior cruciate ligament (ACL) injury in female soccer players. MethodsFrom March to May, 2022, 39 female soccer players from Xi'an Physical Education University were randomly divided into control group (n = 19) and experimental group (n = 20). On the basis of daily training, the control group received sham intervention, and the experimental group received hip neuromuscular training, for six weeks. Before and after training, they were measured dynamic knee valgus (DKV) angle and assessed with Landing Error Score System (LESS); while they were also measured the maximal voluntary isometric contraction (MVIC) and root mean square (RMS) of electromyography as single leg landing of gluteus medius and gluteus maximus. ResultsAll the indexes varied little after training in the control group (|t| < 1.178, P > 0.05), while the indexes improved in the experimental group (|t| > 2.288, P < 0.05), except sagittal score of LESS; and all the indexes improved more in the experimental group than in the control group (|t| > 2.609, P < 0.05), except sagittal score of LESS and MVIC of gluteus maximus. ConclusionHip neuromuscular training can reduce the risk of ACL injury in female soccer players.

EFFECT OF THE COPENHAGEN PROTOCOL AND HOLMICH PROTOCOL FOR CHRONIC GROIN PAIN IN YOUNG ADULT FOOTBALL PLAYERS FOR IMPROVEMENT IN PAIN, STRENGTH AND PERFORMANCE - A COMPARATIVE STUDY

Background: Groin injuries often exhibit major problems, such as high rates of recurrence [3],prolonged durations of absence from sports [1], unclear prognosis [4], and its chronicity [4, 5]. This causes time loss and some of the biggest losses in the performances of the players. Thus it has been a challenge for physiotherapists as well as players who suffer from the injury. Only some advances in the exercise therapy has successfully reduced the time loss and provided significant improvement in the performances later on. Studies done by Holmich et al. and Haroy et al. have provided impressive results in treatment of the players suffering from chronic groin pain and overall reduction of adductor related groin injuries. Testing of this exercise therapy protocols on the parameters of the pain reduction, strength and performance improvement and comparing the results amongst each other is yet to be done on the quantitative and qualitative analysis. Aim: To study and compare the effects of the Holmich protocol and Copenhagen protocol in pain reduction strength improvement and performance improvement among young adult footballers with chronic groin pain. 61 footballers with the Method: chronic groin pain complaints were selected as study subjects. Total sample size was then divided into two groups by odd and even method to form two intervention groups for both the protocols (Group A and Group B). Prevalence was tested on the basis of VAS MMT and Hip and Groin Outcome Scale (HAGOS). These intervention groups performed adductor strengthening protocols during their warm up sessions or as a treatment when the players were unable to play for their respective teams. In our studies we have compared the results Results: of the pre interventional findings with post interventional results in two groups of football players (Group A and Group B). The data was then analyzed for inter-group and intra-group analysis and comparison was done statistically. The results from the studies showed 1) Copenhagen protocol was significantly better in terms of the reducing the pain in subjects. 2) Holmich protocol was significantly better in terms of improvement of the strength in subjects. 3) Copenhagen protocol was significantly better in improvement of the performance of the subjects. Conclusion: Both the adductor strengthening protocols have shown significant improvement in terms of treating the subjects but on the basis of pain reduction and performance improvement Copenhagen protocol showed better success rates. Whereas Holmich protocol has excelled in terms of strength improvement amongst the subjects.

Game Behavior Scale-Electronic (GBS-E): elaboration and psychometric evidence / Escala de Comportamento em Jogo - Eletrônico (ECJ-E): elaboração e evidências psicométricas / Escala de comportamiento en el juego - Electrónico (ECJ-E): elaboración y evidencias psicométricas

Despite the growing engagement in electronic games globally and the need to measure behavior in this context, there are few instruments for this purpose. The present study aimed to develop and validate the Game Behavior Scale-Electronic (GBS-E) in Brazil. In Study 1 (N=409), exploratory factor analysis supported the adequacy of a two-factor solution (individual and collective behavior). In Study 2 (N=373), we used confirmatory factor analysis, item response theory (to evaluate the discrimination and difficulty levels), and graphical factor analysis to test the above version of the scale and propose a short form of the GBS-E. The results suggest that both forms (full form, 31 items and short form, 10 items) of the GBS-E demonstrate psychometric evidence (factorial validity and internal consistency) for the adequacy of the measure to evaluate individual and collective behavior in electronic games. (AU)

Apesar do avanço da prática do esporte eletrônico a nível global e da necessidade de mensurar comportamentos neste contexto, são escassos na literatura instrumentos para este fim. Assim, o presente estudo objetivou elaborar e validar a Escala de Comportamento em Jogo - Eletrônico (ECJ-E) em uma amostra brasileira. No Estudo 1 (N=409) uma análise fatorial exploratória suportou a adequação de uma solução bifatorial (comportamento individual e coletivo). No Estudo 2 (N=373), utilizou-se de análise fatorial confirmatoria, da Teoria de Resposta ao Item (para avaliar os níveis de discriminação e dificuldade) e da análise fatorial gráfica para testar a versão do estudo anterior e propor uma forma curta da ECJ-E. Os resultados sugerem que tanto a forma completa (31 itens) quanto a curta (10 itens) da ECJ-E fornecem evidências psicométricas (validade fatorial e consistência interna) de adequação da medida para avaliar o comportamento individual e coletivo em jogo - eletrônico. (AU)

A pesar del avance de los deportes electrónicos a nivel mundial y la necesidad de medir comportamientos en este contexto, los instrumentos para tal fin son escasos en la literatura. El presente estudio tuvo como objetivo desarrollar y validar la Escala de Comportamiento en el Juego - Electrónico (ECJ-E) en una muestra brasileña. En el Estudio 1 (N=409), un análisis factorial exploratorio apoyó la idoneidad de una solución de dos factores (comportamiento individual y colectivo). En el Estudio 2 (N=373), utilizamos el análisis factorial confirmatorio, la Teoría de la Respuesta al Ítem (para evaluar los niveles de discriminación y dificultad) y el análisis factorial gráfico para probar la versión del estudio anterior y proponer un formulario breve. Los resultados sugieren que el formulario completo (31 ítems) y el breve (10 ítems) del ECJ-E aportan evidencias psicométricas (validez factorial y consistencia interna) de la adecuación de la medida para evaluar el comportamiento individual y colectivo en los juegos electrónicos.

PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20(1), 1-26. El estudio tuvo como objetivo analizar los artículos científicos originales, disponibles en bases de datos en los últimos veintiún años (2000-2021), acerca del monitoreo de la antropometría y aptitud física en jóvenes tenistas. Se realizó una revisión sistemática en tres bases de datos electrónicas: PubMed, LILACS y Web of Science, entre enero del 2000 a mayo del 2021; se identificaron inicialmente 73 artículos originales que, posterior a la aplicación de los criterios de elegibilidad y exclusión, junto con el procedimiento presentado en el flujograma PRISMA, permitieron obtener 14 artículos, que fueron analizados cualitativamente. Los resultados evidencian que existe la necesidad de mayores indagaciones, especialmente a nivel sudamericano y en las mujeres; no obstante, es importante señalar que estos estudios aportan con referencias antropométricas muy similares a las encontradas en otras regiones del mundo. Por otro lado, la antropometría y el desempeño en pruebas de aptitud física presentan mejores indicadores en relación con la edad cronológica, rendimiento en la modalidad (ranking nacional) y entrenamiento específico. Al comparar por género, existen diferencias significativas en antropometría y pruebas de aptitud física. Finalmente, tanto en mujeres como en hombres, la maduración avanzada se asocia al mejor desempeño en las pruebas de velocidad de desplazamiento, de fuerza y potencia muscular. Es necesario considerar esta información para mejorar el rendimiento deportivo, detección de talento y prevenir lesiones en tenistas adolescentes.

PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 20(1), 1-26. The objective of the study was to examine original scientific articles available in data bases for the past twenty-one years (2000-2021) concerning monitoring of anthropometry and physical fitness in young tennis players. A systematic review was carried out in three online data bases (PubMed, LILACS and Web of Science) from January, 2000 to May, 2021. Initially, 73 original articles were identified. After applying criteria of eligibility and exclusion, together with the procedure presented in the PRISMA flowchart, 14 articles were selected and were qualitatively analyzed. The results show the need for further research, mainly in South America and among women. However, it is important to point out that these studies offer anthropometric references very similar to those found in other regions in the world. On the other hand, anthropometry and performance in physical fitness tests show better indicators concerning chronological age, performance in a given modality (national ranking) and specific training. When genders were compared, significant differences were found in terms of anthropometry and physical fitness. Finally, both in women and in men, advanced maturity is associated with better performance in speed tests for movement, strength and muscle power. These data need to be considered in order to improve sports performance, detect talent and prevent injuries in adolescent tennis players.

Abstract Introduction: The present systematic review aimed to compile the information available in the literature having to do with sport psychology regarding futsal and soccer players, in order to identify which psychological constructs are being investigated in these athletes and by means of which instruments and analysis techniques. Method: The search was carried out in the APA (PsycINFO), EBSCO (SportDiscus), PubMed, Web of Science, Scielo, Science Direct, Scopus, BVS and EMBASE databases, with the following descriptors: psychological construct; psychological factor; psychological variable; psychological phenomenon; soccer; futsal and athlete, in English, Spanish and Portuguese. Results: Initially, 66 studies met the established eligibility criteria. Of these, 46 studies were conducted with soccer players, 19 with futsal players and one with athletes who participate in both sports. The psychological constructs most studied in the soccer modality were anxiety, stress, motivation, coping, motivational climate, depression, self-efficacy and group cohesion. With regard to the futsal modality, the most studied psychological constructs were group cohesion, perfectionism, motivation, athlete satisfaction, leadership style, perceived parenting styles and burnout. Conclusions: Group cohesion was associated with several other psychological aspects of an individual nature, with cohesion being the construct of both modalities which is of the greatest interest to researchers possibly because it is a collective modality. It can be established that important psychological factors have not been studied in soccer and futsal modalities, especially among female athletes. Therefore, it is recommended that the research carried out with male athletes be extended to include female populations.

Resumo Introdução: O presente estudo de revisão sistemática procurou compilar informações disponibilizadas na literatura quanto aos estudos da psicologia do esporte em jogadores de futsal e futebol, com a finalidade de identificar quais construtos psicológicos estão sendo estudados nesse público e por quais instrumentos e técnicas de análise. Método: A busca foi realizada nas bases de dados APA (PsycINFO), EBSCO (SportDiscus), PubMed, Web of Science, Scielo, Science Direct, Scopus, BVS e EMBASE, com os seguintes descritores: construto psicológico; fator psicológico; variável psicológica; fenômeno psicológico; futebol; futsal e atleta, nos idiomas inglês, espanhol e português. Resultados: Foram selecionados 66 estudos por meio dos critérios de elegibilidade estabelecidos. Destes, 46 estudos foram conduzidos com jogadores de futebol, 19 com jogadores de futsal e um com atletas de ambas as modalidades. Os construtos psicológicos mais estudados na modalidade de futebol foram ansiedade, estresse, motivação, coping, clima motivacional, depressão, autoeficácia e coesão grupal. Os construtos psicológicos mais estudados na modalidade de futsal foram coesão de grupo, perfeccionismo, motivação, satisfação do atleta, estilo de liderança, estilos parentais percebidos e burnout. Conclusão: A coesão grupal foi associada a diversos outros aspectos psicológicos de natureza individual, sendo a coesão o construto de maior interesse dos pesquisadores de ambas as modalidades, possivelmente, por serem modalidades coletivas. Pode-se identificar que fatores psicológicos importantes não foram estudados nas modalidades de futebol e futsal, em especial junto a atletas do sexo feminino. Recomenda-se, assim, que pesquisas realizadas com atletas do sexo masculino sejam também conduzidas com a população feminina.

Efectos en el estado de bienestar en periodo de confinamiento debido al COVID-19 en jugadores profesionales de fútbol / Effects on the wellness state in period of confinement due to COVID-19 in professional soccer players

Resumen El propósito del estudio fue conocer las alteraciones en el estado de bienestar en periodo de confinamiento debido al COVID-19 en jugadores de fútbol profesional de la primera división B de Chile. Participaron 28 jugadores profesionales de fútbol varones, edad 26 ± 6.3 años, masa corporal de 74.2 ± 5.5 kg y estatura de 177 ± 0.05 cm. Se evaluó el grado de bienestar a través de un cuestionario (McLean et al., 2010) durante periodo competitivo y periodo de confinamiento de la temporada 2020. Se muestran diferencias estadísticamente significativas (p<0.05) entre el periodo competitivo y el periodo de confinamiento, en FT (t = 2.5; p = 0.0), SO (t = 2.71; p = 0.01), ES (t = 5.07; p = 0.0), EA (t = 1.82; p = 0.08) y T (t = 4.87; p = 0.0). Se reflejaron TE pequeños en las variables EA y DM (d = 0.7; d = 0.4 respectivamente), moderados en FT y SO (d = 1.0; d = 1.2 respectivamente) y muy grandes en ES y T (d = 2.1; d = 2.0 respectivamente). Los PC y CV entre periodos para las variables de bienestar fueron para FT 11% y 11.6%, para DM 5.3% y 13.1%, para SO 9.3%; 7.5%, ES 11.6% y 5.9, para EA 3.9%; 5.2%, y finalmente para T 8.1% y 4.0% respectivamente. Es posible concluir que el estado de bienestar en jugadores profesionales de fútbol se ve alterado en el periodo de confinamiento respecto al de competición, encontrándose cambios significativos en las variables FT, SO, ES y T, que coincidieron con los cambios de moderados a muy grandes de estas mismas variables, como también los PC fueron más grandes que el CV entre periodos; por lo que podríamos considerar estos cambios como reales, y que pudiesen ser un efecto atribuible al aislamiento obligatorio.

Abstract This study aimed to find changes in the wellness state, during the confinement period due to COVID-19, in professional soccer players from the first division B of Chile. The studied sample consisted of 28 professional male soccer players aged 26 ± 6.3 years, body mass 74.2 ± 5.5 kg, and height 177 ± 0.05 cm. The degree of well-being was evaluated through a questionnaire (McLean et al., 2010) during the 2020 competitive and confinement periods. Statistically, significant differences (p <0.05) between the competitive period and the confinement period are shown in FT (t = 2.5; p = 0.0), SO (t = 2.71; p = 0.01), ES (t = 5.07; p = 0.0), EA (t = 1.82; p = 0.08), and T (t = 4.87; p = 0.0). Small TE were reflected in the variables EA and DM (d = 0.7; d = 0.4 respectively), moderate in FAT and SO (d = 1.0; d = 1.2 respectively), and very large in ES and T (d = 2.1; d = 2.0 respectively). The CP and CV between periods for the well-being variables were the following: for FAT, 11% and 11.6%, for DM, 5.3% and 13.1%; for SO, 9.3%; 7.5%, ES 11.6% and 5.9, for EA 3.9%; 5.2%, and finally for T 8.1% and 4.0% respectively. It is possible to conclude that the state of well-being in professional soccer players is altered in the period of confinement with respect to that of competition, finding significant changes in the variables FT, SO, ES, and T, which coincided with the changes from moderate to very large of these same variables, as well as the PC were larger than the CV between periods. Therefore, we could consider these changes as real, and they could be an effect attributable to the mandatory isolation.

Effect of somatotype on the general physical fitness tests and throwing velocity on handball

Abstract Aim: The study aimed to investigate the effects of the somatotype components on handball. Methods: The sample consisted of 60 elite junior handball players. Somatotype was evaluated using the Heath & Carter method. The kinetic performance trials of the handball athletes were running speed performance over 5 m 10 m and 20 m sprints, sit and reach, standing long jump (SLJ), ball velocity, and maximum aerobic power. For the data analyses, we used Pearson correlation and multiple linear regression. Results: The endomorphic component correlated positive with all three sprint times (5 m, 10 m και 30 m sprints) (r = 0.315, p = 0.014; r = 0.367, p = 0.004; r = 0.358, p = 0.005 respectively) while negative with SLJ (r = -0.418, p = 0.001) και maximum aerobic power (r = -0.322, p = 0.012). The mesomorphic component had a positive correlation with ball velocity (r = 0.260, p = 0.045) and negative relation with SLJ (r = -0.261, p = 0.044). The ectomorphic component exhibited a negative correlation only with ball velocity (r = -0.260, p = 0.045). The ordinary least square regression models found that endomorphy and ectomorphy were prognostic factors and predicted worse performance in all of the examined motor performance indices except ball velocity and 5 m sprint, while mesomorphy was a predictor of worse performance in SLJ. Conclusions: In conclusion, according to the findings of this study, somatotype components play an important role in performance-related parameters.

SUMMARY: This research aimed to determine the differences between the junior (U18) water polo players of five Croatian and one Montenegrin clubs in the anthropometric characteristics and body composition. The first sample of the subjects consisted of 14 players of the water polo club Mladost average age 17.57±0.65, the second sample consisted of 11 players of the water polo club Sibenik (17.82±0.65), the third sample consisted of 13 players of the water polo club Primorje (17.23±1.01), the fourth sample consisted of 15 players of the water polo club Mornar (17.13±0.64), the fifth sample consisted of 13 players of the water polo club Medvescak (17.92±0.76) and the sixth sample consisted of 10 players of the water polo club Jadran Herceg Novi (Montenegro) (17.70±1.34). In the 2010-11 season, these clubs participated in Regional Water Polo League, commonly known as the Regional League or Adriatic League in Southeast Europe. The measurements was conducted in the competition season in the period September-December 2010, at sports centers and swimming pools of water polo clubs that participated in the research. Anthropometric characteristics and body composition were evaluated using a battery of 12 variables: body height, body weight, arm length, arm span, leg length, foot length, chest skinfold, triceps skinfold, back skinfold, abdominal skinfold, upper leg skinfold and body mass index. The standard central and dispersion parameters of all variables were calculated. The significance of the differences between the water polo players of six teams in the variables for assessing anthropometric characteristics and body composition were determined using ANOVA and an LSD Post Hoc test.Based on the central and dispersion parameters, it can be stated that the values of all the variables are highly similar to all of the water polo players of these six clubs. The ANOVA test found that the water polo players of the six international clubs do not have statistically significant differences in the variables for assessing anthropometric characteristics and body composition.

The actual conditions of rugby-related head injuries in Japanese high school players: The analysis of injuries reports between April 2009 and March 2016 of Kansai rugby football association / 体力科学

The present study was performed to ascertain the annual changes in the number and nature of traumatic head injuries that occur in high-school rugby matches, and as an exploratory investigation of approaches to improve safety in the future. It was based on injury reports submitted at the time of injury to the Kansai Rugby Football Union between Apr. 2009 and Mar. 2016. The finding was that the mean number of reported cases of traumatic head injury per year during the three pre-amendment years from Apr. 2009 to Mar. 2011 was 18.0, whereas that during the five post-amendment years from Apr. 2012 to Mar. 2016 was 36.2. Of all the traumatic head injuries, those with the highest numbers and proportions of cases for each of the four factors were as follows: (i) occasion of injury: during a match, 115 (48.9%); (ii) condition of the pitch: grass, 105 (44.7%); (iii) school grade: 2, 104 (44.3%); and (iv) cause of injury: tackling, 115 (48.9%). In addition, the odds ratios (ORs) for brain concussion at post-amendment as compared with pre-amendment and for occurrence on grass as compared with on soil were significant 2.83. An exploratory investigation was conducted to clarify whether different factors are associated with the severity of pre- and post-amendment injuries, but no significant ORs were found. In conclusion, the establishment of guidelines related to brain concussion in 2012 increased the number of reports of injuries due to high-school rugby and had a definite effect on prompt treatment of brain concussions.

Handball injuries among high school players in Japan / 体力科学

The purpose of this study was to investigate the injury patterns and risk factors of injuries among high school handball players in Japan. A total of 1299 (709 male and 590 female) subjects who played in the 2018 Japanese National High School Handball Championship participated in this study. The questionnaire on injury experience was distributed two weeks before the championship and was collected at the representation meeting the day before the championship. The main results were as follows: 1) The subjects (n=625, 48.1%) reported experiences of injuries in the previous year. Female had significantly more suffer injuries than male. 2) The main body parts of injuries were the ankle, knee, and finger in traumatic injuries and the lower leg, lumber spine/lower back, and knee in overuse injuries. The main types of injuries were sprain, ligamentous rupture, and fracture in traumatic injuries and stress fracture, other bone injuries, and lesion of meniscus or cartilage in overuse injuries. The main cause of injuries was “contact with another athlete”. 3) Age, female players, and back players were associated with increased the occurrences of injuries. Goalkeepers were associated with decreased the occurrences of injuries. These results indicated that a high prevalence of injuries in high school handball players, and it is important to take preventive measures based on age, gender, and player position.

Differences in anthropometrics characteristics and body composition between two elite youth male basketball national teams - participants at u18 European Championship 2019 / Diferencias en las características antropométricas y la composición corporal entre dos equipos nacionales de baloncesto masculino juvenil de élite - participantes en el Campeonato de Europa u18 2019

SUMMARY: The aim of this research was to determine the differences among the male basketball players of the National team of Montenegro U18 and the National team of Republic of North Macedonia, in terms of their anthropometric characteristics and body composition. A sample of 27 subjects was divided into two sub-samples. The first sub-sample of the subjects consisted of 15 players of the National team of Montenegro, average age 17.6±0.63, while the other sub-sample consisted of 12 players of the National team of Republic of North Macedonia, average age of 17.17± 0.72. All players were tested in Podgorica, in lasting period of two days, while they held preparations for the European Championship. Anthropometric characteristics and body composition were evaluated by a battery of eleven variables: body height (cm), body weight (kg), triceps skinfold, back skinfold, biceps skinfold, abdominal skinfold, thigh skinfold, calf skinfold, body mass index (BMI), percentage of fat and muscle mass (kg). Differences in anthropometric characteristic and composition of the body of the basketball players of two national teams were determined by using a discriminatory parametric procedure with t-test for small independent samples (p<0.05). The players of the two teams were found to differ statistically in thigh skinfold. Furthermore, it is concluded that Montenegro players are taller and heavier and have higher muscle mass than North Macedonian players, with approximate skinfolds, BMI and fat percentage values.

RESUMEN: El objetivo de esta investigación fue determinar las diferencias en las características antropométricas y composición corporal entre los jugadores de baloncesto masculino del equipo nacional de Montenegro U18 y el equipo nacional de la República de Macedonia del Norte. Una muestra de 27 sujetos se dividió en dos submuestras. La primera sub muestra consistió en 15 jugadores del equipo nacional de Montenegro, con una edad promedio de 17,6 ± 0,63 años. La otra muestra consistió en 12 jugadores del equipo nacional de la República de Macedonia del Norte, con un promedio edad de 17,17 ± 0,72 años. Todos los jugadores fueron evaluados en Podgorica, durante un período de dos días, mientras realizaban los preparativos para el Campeonato de Europa. Las características antropométricas y la composición corporal se evaluaron mediante una batería de once variables: altura (cm), peso (kg), pliegue de tríceps, pliegue de espalda, pliegue de bíceps, pliegue abdominal, pliegue de muslos, pliegue de pantorrilla, índice de masa corporal (IMC), porcentaje de grasa y masa muscular (kg). Se determinaron las diferencias en las características antropométricas y la composición del cuerpo de los jugadores de baloncesto de dos equipos nacionales a través de un procedimiento paramétrico discriminatorio con prueba t para muestras independientes (p <0,05). Se determinó que los jugadores de ambos equipos difieren estadísticamente en el pliegue del muslo. Además, se concluyó que en comparación con los jugadores de Macedonia del Norte los jugadores de Montenegro son de mayor altura y peso, además de contar con una mayor masa muscular, con valores aproximados de pliegues cutáneos, IMC y porcentaje de grasa.
