ABSTRACT

INTRODUCTION: Introduction: to combat the COVID-19 pandemic governments have adopted measures such as quarantine and social distancing. Objective: the main objective of the present study was to analyze the impact of COVID-19 quarantine on body mass in combat sports athletes. Methods: we conducted a cross-sectional, prospective, multi-center study that evaluated 234 men (mean age and standard deviation, 29 ± 10 years) residing in Argentina (n = 38); Bolivia (n = 1); Brazil (n = 105); Chile (n = 30); El Salvador (n = 1); Spain (n = 22); Mexico (n = 22) and Peru (n = 15). Of these, 12 practiced Brazilian jiu-jitsu (BJJ), 54 boxing, 67 judo, 13 karate, 52 kick boxing & muay thai (KB & MT), 9 mixed martial arts (MMA), and 27 taekwondo (TKD). An online survey was created using Google Forms. It was implemented between April 4th and April 17th, 2020. Athletes were consulted about their body mass before starting the quarantine and after 20 ± 5 days of quarantine. Results: athletes in all combat sports were heavier during quarantine as compared to pre-quarantine (p < 0.001, d = 0.12). Conclusions: combat sports athletes experienced an increase in body mass during the COVID-19 quarantine.


INTRODUCCIÓN: Introducción: para combatir la pandemia de COVID-19, los gobiernos han adoptado medidas como la cuarentena y el distanciamiento social. Objetivo: el principal objetivo del presente estudio fue analizar el impacto de la cuarentena por COVID-19 sobre la masa corporal en atletas de deportes de combate. Métodos: realizamos un estudio transversal, prospectivo y multicéntrico que evaluó a 234 hombres (media de edad y desviación estándar, 29 ± 10 años) que residen en Argentina (n = 38); Bolivia (n = 1); Brasil (n = 105); Chile (n = 30); El Salvador (n = 1); España (n = 22); México (n = 22) y Perú (n = 15). De estos, 12 practicaban jiu-jitsu brasileño (BJJ), 54 boxeo, 67 judo, 13 karate, 52 kick boxing y muay thai (KB y MT), 9 artes marciales mixtas (MMA) y 27 taekwondo (TKD). Se creó una encuesta en línea usando Google Forms. Se implementó entre el 4 y el 17 de abril de 2020. Se preguntó a los deportistas sobre su masa corporal antes de comenzar la cuarentena y después de 20 ± 5 días de cuarentena. Resultados: los atletas de todos los deportes de combate resultaron más pesados durante la cuarentena que durante la precuarentena (p < 0,001, d = 0,12). Conclusiones: los atletas de deportes de combate presentaron una mayor masa corporal durante la cuarentena a causa de la COVID-19.

ABSTRACT

INTRODUCTION: Introduction: To avoid rapid bodyweight fluctuations and the associated effects on health and performance, some combat sports federations have made changes to regulations. Objective: the objective of this study was to analyze the impact of the Rapid Weight Gain on sporting success in elite Olympic Wrestling athletes under the new weighing modality. Methods: the bodyweight of 75 athletes was recorded during the Pan-American Olympic Wrestling Championship (Lima, 2018), corresponding to 29 % of the total universe of competitors (n = 255). Of these, 29 were Greco-Roman style, eight Freestyle, and 38 Women´s Wrestling. The official weighing was carried out between 8:00 and 8:30 hours. As for the second weighing, this was done with the same official weighing scale, immediately before the first match (between 10:00 and 11:00 hours). Rapid Weight Gain after weigh-in was compared between medalist and non-medalist athletes. Results: when analyzing the difference between medalists and non-medalists, no significant differences were found in Greco-Roman athletes (t = 0.114; p = 0.910; r = 0.022), in Freestyle (Mann-Whitney U = 5,500; p = 0.486; r = 0.000), in Women´s Wrestling (Mann-Whitney U = 163.0; p = 0.774; r = 0.124), and in all competitors (Mann-Whitney U = 641.5; p = 0.855; r = 0.037). Conclusions: no significant differences were found between medalist and non-medalist athletes in any of the Olympic Wrestling styles.


INTRODUCCIÓN: Introducción: para evitar fluctuaciones rápidas del peso corporal y los efectos asociados sobre la salud y rendimiento, algunas federaciones de deportes de combate han realizado cambios de reglamento. Objetivo: el objetivo de este estudio fue analizar el impacto de la ganancia rápida de peso en el éxito deportivo en atletas de élite de la lucha olímpica bajo la nueva modalidad de pesaje. Métodos: se registró el peso corporal de 75 atletas durante el Campeonato Panamericano de Lucha Olímpica (Lima, 2018), correspondiente al 29 % del universo total de competidores (n = 255). De estos, 29 fueron de estilo grecorromano; 8, de estilo libre y 38, de lucha libre femenina. El pesaje oficial se realizó entre las 8:00 y las 8:30 horas. En cuanto al segundo pesaje, se hizo con la misma balanza oficial inmediatamente antes de la primera lucha (entre las 10:00 y las 11:00 horas). La ganancia de peso rápida después del pesaje se comparó entre atletas medallistas y no medallistas. Resultados: al analizar la diferencia entre medallistas y no medallistas, no se encontraron diferencias significativas en los atletas de grecorromana (t = 0,114; p = 0,910; r = 0,022), en los de estilo libre (Mann-Whitney U = 5,500; p = 0,486; r = 0,000), en los de lucha libre femenina (Mann-Whitney U = 163,0; p = 0,774; r = 0,124) ni en todos los competidores (Mann -Whitney U = 641,5; p = 0,855; r = 0,037). Conclusiones: no se encontraron diferencias significativas entre atletas medallistas y no medallistas en ninguno de los estilos de lucha olímpica.

ABSTRACT

INTRODUCTION: Introduction: child excess weight has been associated with obesity in adulthood and, as a consequence, increased risk of death due to cardiometabolic factors. Objective: to identify whether BMI reflects changes in the content and distribution of fat/adipose tissue and the cardiometabolic risk in children between six and nine years old. Material and methods: participants were 537 children (59.8% women) randomly selected. BMI, waist circumference (WC), waist-height index (WHI), body composition, nutritional status and cardiometabolic risk were determined. Student's t-test, one-way ANOVA, Pearson's correlation, Chi-square and diagnostic concordance were applied. An alpha ≤ 0.05 was considered. Results: direct and significant correlations between nutritional status and the anthropometric parameters studied are shown, except for the percentage of adiposity. There were significant variations (p < 0.05) in the percentage of fat and adiposity according to nutritional status of the sample. In addition, there was consistency between the variation of the nutritional status with the cardiometabolic risk evaluated trough WC and WHI. Conclusion: BMI identifies the differences in the amount of fat/adipose tissue in the children between six and nine years old when categorized according to nutritional status. In addition, it reflects direct association with cardiometabolic risk.


INTRODUCCIÓN: Introducción: el exceso de peso infantil se ha asociado con obesidad en la etapa adulta y, por consecuencia, mayor riesgo de muerte por factores cardiometabólicos. Objetivo: identificar si el índice de masa corporal (IMC) refleja cambios en el contenido y la distribución del tejido graso/adiposo y el riesgo cardiometabólico en niños y niñas de seis a nueve años. Material y métodos: participaron 537 niños (59,8% mujeres) seleccionados aleatoriamente. Las variables estudiadas correspondieron al IMC, perímetro de cintura (PC), índice cintura-estatura (ICE), composición corporal, estado nutricional y riesgo cardiometabólico. Se utilizó la prueba de correlación de Pearson y Chi-cuadrado para la relación de las variables junto con la aplicación de un test de proporciones. Se aplicaron las pruebas t de Student para muestras no pareadas, ANOVA una vía y concordancia diagnóstica en la comparación entre grupos. Se consideró un alfa ≤ 0,05 para todos los casos. Resultados: se exhiben correlaciones directas y significativas entre el estado nutricional con los parámetros antropométricos estudiados, excepto el porcentaje de adiposidad. Se aprecian variaciones significativas (p < 0,05) en el porcentaje de grasa y adiposidad según estado nutricional de la muestra. Además, existe consistencia entre la variación del estado nutricional con el riesgo cardiometabólico evaluado a través del PC e ICE. Conclusión: el IMC identifica las diferencias en la cantidad de tejido graso/adiposo en niños y niñas situados entre los seis y los nueve años al ser categorizados según estado nutricional. Además, refleja asociación directa con el riesgo cardiometabólico.

ABSTRACT

This systematic review analyzes the evidence of the effects of physical activity governmental programs oriented toward the health of independent older adults. Medline, Web of Science, PsycINFO, and Psychology & Behavioral Sciences Collection databases were used for data mining, and the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols recommendations were followed. Five studies (n = 2,545 participants) fulfilled the established inclusion criteria. The physical activity programs had beneficial effects on the older adults' quality of life, fall risk, activities of daily living, physical activity levels, nutritional risk, body mass index, arterial pressure, resting heart rate, blood glucose, triglycerides, and/or cholesterol, but did not significantly alter their body fat mass percentage. Programs involving diverse physical capacities seem to be more effective for healthy aging. It is recommended that governments start to disseminate the outcomes of these programs within society and the scientific community.

ABSTRACT

INTRODUCTION: Programs focused on active aging do not always have actions to guide the elderly about healthy eating. Therefore, the concordance between the feeding habits and the morphological characteristics of this population group is little known. OBJECTIVE: To correlate the anthropometric health indexes with the frequency of food consumption in physically active elderly (PAE). METHODS: The sample consisted of 307 physically active Chilean elders of both sexes (8.4% males), with a mean age of 70.2 years. The studied variables corresponded to nutritional status, abdominal adiposity, cardiovascular risk and frequency of food consumption. A logistic regression model was applied, considering alpha < 0.05. RESULTS: Fruit intake (OR = 0.12; 95% CI, 0.02-0.92) and water consumption (OR = 0.20; CI 95%, 0.04-0.90) are shown as protective factors for obesity; on the other hand, alcohol consumption (OR = 4.19; 95% CI, 1.03-17.02) and sweet snacks (OR = 10.68; 95% CI, 1.85-61.74) are presented as risk factors for obesity. In addition, vegetable intake (OR = 0.32; 95% CI, 0.11-0.92) was associated as a protective factor against abdominal adiposity and sweet snack consumption (OR = 6.45; 95% CI, 1.08-38.43) as a factor to present cardiovascular risk. CONCLUSION: The PAE that are more frequent in the consumption of healthy foods also show better nutritional status, abdominal adiposity and lower cardiovascular risk than active Chilean elderly who exhibit less healthy eating behavior.

ABSTRACT

La alta tasa de sedentarismo y obesidad reportada en Chile, ha propiciado la aparición de diversos programas deportivos para niños y adolescentes, que requieren evaluaciones fiables en torno a las características antropométricas por disciplina Deportiva. En este sentido, la presente investigación pretende por objetivo determinar las características antropométricas de adolescentes pertenecientes a distintas escuelas deportivas formativas (AD) de Temuco, Chile y su relación con parámetros deportivos ideales. El tipo de investigación contempla un diseño no experimental, descriptivo, transversal, con un enfoque cuantitativo. La muestra estuvo constituida por 65 sujetos (38 mujeres) con un promedio de edad de 15,9 (2,5) años y un IMC de 22,8 (4) kg/m2, quienes practicaban taekwondo (n= 4), racquetbol (n= 6), esgrima (n= 7), karate (n= 8), atletismo (n= 13), tenis (n= 6) y fútbol (n= 21). Los resultados indican que las AD mujeres promediaron un somatotipo de 4,9 ­ 4,3 ­ 1,5 (clasificadas como endomesomorfas), masa adiposa de 33,6% y masa muscular de 39,7%, mientras los AD varones para las mismas variables ostentan 3 ­ 4,9 ­ 2,3 (mesoendomorfos), 27,4% y 43,7%. En conclusión, los AD evaluados ostentan normopeso, su composición corporal exhibe una elevada masa adiposa incluso para parámetros normales, mientras que su somatotipo parece acercarse a los ideales deportivos, sin evidenciar una tendencia por disciplina deportiva. Se sugiere para futuras investigaciones estudiar otras variables, como los programas de entrenamiento, el rendimiento deportivo y los hábitos alimentarios, con la intención de obtener respuestas más satisfactorias respecto a los factores que influyen en la proyección de adolescentes al deporte competitivo.


The high rate of physical inactivity and obesity reported in Chile, has given rise to various sports programs for children and adolescents who require reliable assessments of anthropometric characteristics for sports. In this sense, this research aims to determine the anthropometric characteristics of adolescents belonging to different training sports schools (AD) of Temuco, Chile and its relationship with ideal athletic parameters. The research provides a non-experimental, descriptive, transversal, with a quantitative approach to design. The sample consisted of 65 subjects (38 women) with a mean age of 15.9 (2.5) years and a BMI of 22.8 (4) kg/m2, who practiced taekwondo (n= 4), racquetball (n= 6), fencing (n= 7), karate (n= 8), athletics (n= 13), tennis (n= 6) andsoccer (n= 21). The results indicated that AD women were classified as endo-mesomorphic (4.9 ­ 4.3 ­ 1.5) with a mean percentage of 33.6% fat mass and 39.7% muscle mass, while the AD males were classified as meso-endomorphic (3 ­ 4.9 ­ 2.3) and they presented a 27.4% of fat mass and a 43.7% of muscle mass. In conclusion, although the AD evaluated showed normal weight, their body composition exhibits a high percentage of fat mass, even in comparison with normal parameters. Nevertheless, its somatotype was closer to the kineanthropometric profile ideal for sports, without showing any trend by sport. Further studies will be required to understand the role of training programs, athletic performance and eating habits in the optimization of sports performance.

ABSTRACT

Los cambios demográficos y sociales están produciendo un incremento progresivo de las personas de más de 60 años a nivel mundial, situación que no es distinta en Chile, por lo que estudiar variables relacionadas con este grupo de la población se vuelve importante. En este sentido, la presente investigación tiene por objetivo conocer el perfil antropométrico y condición física de jugadores veteranos de basquetbol (JVB). El tipo de investigación contempla un diseño descriptivo, transversal, con un enfoque cuantitativo. La muestra seleccionada incluyó a 30 JVB (edad 66,7±6,8 años) pertenecientes a la liga de la Asociación de Básquetbol Sénior de la Región de la Araucanía, Chile. Las variables dependientes estudiadas corresponden a la composición corporal, somatotipo y condición física (fuerza, resistencia aeróbica, flexibilidad, agilidad y equilibrio dinámico). Los resultados indican que los JVB mostraron un componente endomórfico, mesomórfico y ectomórfico de 4,1, 6,1 y 1,0, respectivamente, clasificándolos como meso-endomorfos, con una masa muscular de 45% y masa grasa de 24,5%. La condición física de los JVB presentó un rendimiento igual (40% de los JVB) o superior (40% de los JVB) al esperado según edad y sexo. En conclusión, los JVB poseen un perfil antropométrico y condición física favorable de acuerdo a su edad y sexo, sugiriendo que la práctica sistemática de básquetbol permitiría impactar positivamente sobre la composición corporal y el rendimiento físico-funcional en adultos mayores, sin embargo se requiere de mayor investigación para poder afirmarlo.


The demographic and social changes are causing a gradual increase in people over 60 years worldwide, situation thar is similar in Chile, so the study of variables related to this group of the population becomes important. In this regard, the aim of this study is to determine the anthropometric and physical fitness profile of senior basketball players (SBP). This is a descriptive, cross-sectional, quantitative research. The sample included 30 SBP (age 66.7±6.8 years) belonging to the league of the Senior Basketball Association of the Araucanía Region, Chile. The dependent variables studied correspond to body composition, somatotype and fitness (strength, endurance, flexibility, agility and dynamic balance). Results indicate that the SBP showed endomorphic, mesomorphic and ectomorphic values of 4.1, 6.1 and 1.0, respectively, as meso-endomorphs with a muscle mass of 45% and body fat of 24.5%. Compared to age and sex counterparts, SBP exhibit equal (40% of SBP) or even higher (40% of SBP) values for physical fitness perfomance variables. In conclusion, SBP have a favorable anthropometric and physical fitness profile for their age and sex, suggesting that the systematic practice of basketball would have a positive impact on body composition and physical fitness-function in older adults, however more experimental research is needed to corroborate this.

ABSTRACT

Las publicaciones referidas a personas con discapacidad visual que practican Goalball son escasas, dado a estudiar otros grupos de la población o bien por razones que se desconocen. El objetivo de esta investigación fue medir el somatotipo, composición corporal, estado nutricional y condición física por aspectos estructurales y funcionales en personas con discapacidad visual que practican Goalball en la región de la Araucanía. El tipo de investigación contempla un diseño no experimental, descriptivo, transversal, con un enfoque cuantitativo. La población estuvo constituida por 14 deportistas de Goalball de la región de la Araucanía, Chile. La muestra fue seleccionada bajo un criterio probabilístico, que incluyo a 11 personas, todos hombres (edad 42,36±14,46 años), en relación al peso y estatura la media fue de 74,76±10,36 kg y 1,695±0,07 m, respectivamente. Para medir el somatotipo y la composición corporal se utilizó el protocolo descrito por la Sociedad Internacional para el avance de la Kineantropometría (ISAK) y para evaluar el estado nutricional y la condición física, se utilizaron las pruebas empleadas en el Sistema de medición de la calidad de la educación (SIMCE) para el subsector de Educación Física, propuestos por el Ministerio de Educación de Chile (MINEDUC). Los resultados indican que los deportistas evaluados se clasifican como mesoendomorfos, alcanzando un 28,78% de masa grasa y 42,71% de masa muscular, mientras que su IMC fue 26,05 kg/m2. En cuanto a la condición física los valores encontrados señalan que se encuentran en un nivel satisfactorio para las pruebas de abdominales, flexibilidad y resistencia cardiorrespiratoria, mientras que ostentan malos resultados para las pruebas de salto largo a pies juntos y flexoextensión de codos, situación que se puede entender por la edad, discapacidad y características de la disciplina deportiva practicada.


Few publications refer to people with a visual impairment who practice Goalball, given that other groups of the population were studied or for unknown reasons. The aim was to measure the somatotype, the body composition, the nutritional state, and the physical condition (more specifically structural and functional features) of people with visual impairment in the Araucanía Region in Chile. The type of investigation considers a cuantitative, non-experimental, descriptive and transversal design. The sample consists of 14 Goalball athletes of the Araucanía Region. The sample was selected randomly and included 11 male subjects (age 42.36±14.46), with respect to weight and height the average was 74.76±10.36 and 1.695±0.07 respectively. To measure the somatotype and the body composition, the protocol described by the International Society for the Advancement of Kinanthropometry (ISAK) was used, whereas to evaluate the nutritional state and physical condition, the tests employed in the SIMCE (System of Measuring the Quality of Education) for the subsector of Physical Education in Chile (MINEDUC ­ Ministry of Education) were administered. The results indicate that the evaluated athletes classify as meso-endomorph. They reached 28.78% of fat mass and 42.71% of muscle mass, whereas their BMI is 26.05kg/m2. Regarding their physical condition the findings show a satisfactory level for the tests of abdominals, flexibility, and cardiorespiratory resistence. The tests of long jump with joined feet and elbow-flexo-extention were not as good, however. These outcomes can possibly be explained by the age, visual impairment, and by characteristics of the sport discipline practiced.
