Small-sided games as additional training in elite basketball nonstarters players / Juegos reducidos como entrenamiento adicional para jugadores suplentes de baloncesto de élite / Jogo reduzido como treino adicional para jogadores reservas de basquetebol de elite

ABSTRACT Introduction: Among the main challenges faced by coaches of team sports are to create an environment and conditions that will enable players to reach their optimal level of physical performance at the start of the competitive season, and to maintain this level throughout the season. Objective: The purpose of this study was to assess the effects of six weeks of additional training with 3-against-3 (3v3) small-sided games (SSG) on the physical performance of elite nonstarter basketball players. Methods: Eleven professional basketball players (five starters and six nonstarters) performed the same training program throughout the regular season, with the only difference that after each game, the starters (S) performed low intensity shooting drills while the nonstarters (NS) performed half-court 3v3 SSG. At the start and end of the six-week period, the athletes were assessed for muscle power, speed, agility and aerobic power. Two-way analysis of variance and effect sizes were used. Magnitude-based inferential analyses were used to complement the parametric tests. Results: After the six weeks, the S and NS showed improvement (p<0.05) in the squat jump (S=5.8% and NS=7.1%), counter movement jump (S=3.7% and NS=3.6%), 20m-sprint (S=3.4% and NS=2.0%), agility T test (S=3.6% and NS=3.1%) and Yo-yo intermittent recovery (S=5.2% and NS=2.5%). No differences were found between groups and moments. The effect sizes showed moderate effect on agility and little effect on jumping ability, for both groups; moderate, for S, and little, for NS, on speed and aerobic conditioning. Magnitude-based inferences indicated that S were likely to outperform NS in terms of improvement in 20-m sprint ability and possibly also in agility. In regard to the other physical performance variables, the analyses of magnitude-based inferences were inconclusive. Conclusions: The results of this study showed that 3v3 SSG in the short-term on half-court, as an additional training routine for NS, can bring positive results for the physical performance for these players.

RESUMEN Introducción: Uno de los principales desafíos de los entrenadores de deportes colectivos es crear ambiente y las condiciones que permitan a los jugadores alcanzar su nivel ideal de desempeño físico al inicio de la temporada competitiva y mantener ese nivel a lo largo de la temporada. Objetivos: El objetivo de este estudio fue evaluar los efectos de seis semanas de entrenamiento adicional con juegos reducidos (JR) 3 contra 3 (3x3) sobre el desempeño físico de jugadores suplentes del baloncesto de élite. Métodos: Once jugadores profesionales (cinco titulares y seis suplentes) realizaron el mismo programa de entrenamiento durante la temporada regular, con la única diferencia de que, después de cada partido, los titulares (T) realizaban ejercicios de lanzamiento de baja intensidad, mientras que los suplentes (S) realizaban JR 3x3 en media cancha. Al inicio y al final de cada período de seis semanas los atletas fueron evaluados en cuanto a la potencia muscular, velocidad, agilidad y potencia aeróbica. Fueron usados análisis de variancia y tamaños de efecto de dos vías. Fueron usados análisis inferenciales basados en magnitud para complementar los tests paramétricos. Resultados: Después de seis semanas, el grupo T y el S mostraron mejora (p <0,05) en el salto con agachamiento (T = 5,8% y S = 7,1%), salto contramovimiento (T = 3,7% y S = 3,6%), sprint de 20 metros (T = 3,4% y S = 2,0%), test T de agilidad (T = 3,6% y S = 3,1%) y el test de recuperación intermitente Yo-yo (T = 5,2% y S = 2,5%). No fueron encontradas diferencias entre grupos y momentos. Los tamaños de efecto mostraron efecto moderado en la agilidad y pequeño efecto en la capacidad de salto para ambos grupos; efecto moderado para el grupo T y pequeño para el S, en la velocidad y acondicionamiento aeróbico. Las inferencias basadas en la magnitud indicaron que el grupo T probablemente superaría al grupo S en términos de mejora de la habilidad de sprint de 20 metros y posiblemente también en agilidad. El análisis de las inferencias basadas en magnitud no fue concluyente con relación a las otras variables. Conclusiones: Los resultados de este estudio mostraron que JR 3x3 en media cancha como entrenamiento adicional para el grupo S puede ser positivo para el desempeño físico de esos jugadores.

Hemoglobina glicada y ejercicio: una revisión sistemática / Effects of physical training in patients with type 2 diabetes mellitus: a systematic review

Physical training is recommended in several studies and guidelines for the control of type 2 diabetes mellitus (DM2) and its complications. We performed a systematic review about the effects of aerobic training (AT), resistance (RT) or the combination of both (AT/ RT), on glycated hemoglobin (HbA1c) in patients with DM2. Therefore, we included 15 clinical trials with at least 12 weeks duration about training program or recommendations of physical exercise, that evaluated the reduction in HbA1c levels in patients with DM2. Information was obtained on training modality (AT, RT or AT / RT), training parameters, duration and weekly training frequency. The results showed increases in peak or maximal oxygen uptake, exercise tolerance time and muscle strength, depending on the type of training, and a reduction in HbA1c levels. We conclude that exercise training is associated with reductions of HbA1c in patients with DM2. Thus, it can be a complementary tool in the management of these patients.

Estimated intensity and acute cardiovascular response to a single exercise session guided by the fitness app Sworkit® Personal Trainer

Aim: The aim of the present study was to evaluate the effect of an exercise session prescribed by the Sworkit® Personal Trainer application on hemodynamic and autonomic responses. Methods: The sample consisted of 11 men classified as sedentary according to IPAQ. The exercises were randomly selected by the app Sworkit® Personal Trainer, using the pre-built program "Light Warm-Up Cardio" (see supplementary material). Heart rate and perceived exertion data were collected every minute during an exercise session. Blood pressure and heart rate variability were measured Pre, Post, 30 min, 12h, 24 h, and 48h after exercise. Heart rate and rate of perceived exertion were collected during the 30 minutes exercise. Results: Hemodynamic responses showed differences in heart rate and systolic blood pressure: Post, 12 h and 24 h compared to Pre. We also found significant statistical differences in the heart rate variability indexes when comparing Post, 30min to 48h versus Pre, indicating modifications in the autonomic modulation post-exercise. The perceived exertions scale remained between 13-14 during the exercise. Heart rate was 149 ± 5.26 (80 ± 5% of HRmax) during the 30min exercise, indicating a moderate to vigorous intensity. Conclusion: We concluded that a single exercise session guided by the Sworkit® Personal Trainer application could generate autonomic changes in up to 12 hours, presenting a moderate to vigorous intensity in 30 minutes of exercise for sedentary men.(AU)

Improvement in muscular strength and aerobic capacities in elderly people occurs independently of physical training type or exercise model

OBJECTIVES: Progressive decline of physiological processes with aging is normal. Aging is also associated with decreased functional capacity and onset of many diseases. This study evaluated the changes in physical fitness (PF), body composition (BC), and lipid profile (LP) in elderly men completing different training protocols. METHODS: Fifty-five men (age 60-80 years) were randomized into the following groups: without training, aerobic training on dry land, combined training on dry land, and combined training in water. Training was conducted for 8 weeks, and PF, LP, and BC were assessed at the beginning and end of the intervention. RESULTS: Significant improvements were observed in all parameters; however, combined programs on land or in water were more effective at improving strength and aerobic fitness. Combined exercise produced greater effects on BC and LP and some muscle fitness parameters; however, improvements in muscular and aerobic capacities occurred independently of exercise type or model. CONCLUSION: These results indicate that the effects of training occur regardless of training type or model, and are directly associated with training periodization, adherence, and regularity.

Aplicaciones médicas de las cámaras de oxigenación hiperbárica de nueva generación / Medical applications of new generation hyperbaric oxygenation chambers

El uso clínico de la terapia de oxigenación hiperbárica (TOHB) consiste en respirar oxígeno en una concentración cercana al 100% en una cámara presurizada al menos a 1,4 atmósferas absolutas (atm). TOHB actúa produciendo hiperoxia y especies reactivas del oxígeno que desencadenan mecanismos bioquímicos variados. Se presenta una revisión de todas las nuevas aplicaciones emergentes de TOHB en varias especialidades médicas debido a que alcanza beneficios en la cicatrización de heridas, enfermedades inflamatorias y con componente neurológico o isquémico. Las nuevas cámaras realizan el tratamiento a presiones más seguras y con la misma eficiencia demostrada por métodos matemáticos y bioquímicos. El Grupo BioBárica Clinical Research presenta la estadística de las indicaciones en 559 pacientes tratados con estas cámaras en algunos centros médicos y las especialidades médicas implicadas. El uso de TOHB a media presión está en emergencia y podría proveer a futuro evidencia de su efectividad en otras especialidades médicas. (AU)

The clinical use of Hyperbaric Oxygen Therapy (HBOT) consists in breathing oxygen (O2) near to 100% in a pressurized chamber of at least at 1.4 absolute atmospheres (ATA). HBOT acts producing both hyperoxia and reactive oxygen species (ROS) and triggers others biochemical events. The BioBarica Clinical Research Group is developing clinical evidence in diverse pathologies because of accessibility and safety of the new Revitalair hyperbaric oxygen chamber. Because of working at "mild pressure", HBOT performed by these chamber are safer demonstrated by mathematical and biochemical methods. The BioBarica Clinical Research Group presents the statistics of the indications in 559 patients treated with these cameras in some medical centers and the medical specialties involved. Their accessibility to the physicians would become mild pressure HBOT used more frequently proving its effectiveness in other clinical specialties. (AU)

Effect of post-activation potentiation in Athletics: a systematic review / Efeito da potencialização pós-ativação no Atletismo: uma revisão sistemática

Abstract Post-activation potentiation is a physiological phenomenon reported to increase muscle performance during high-intensity exercise. To induce post-activation potentiation, maximal strength or power short-duration activities are performed minutes prior the main activity in an attempt to enhance performance. The aim of this study was to evaluate previous publications on the effects of post-activation potentiation on athletic performance. This systematic review used Scielo, Pubmed and SporDiscus database with the following search terms either alone or grouped together: post-activation potentiation, exercise, athletics, track and field, sprint, long jump, triple jump, high jump, shot put, javelin throw, hammer throw e discus throw. The review provided evidence that performing squat, jump and sprint exercises prior to the main activity elicited a state of potentiation that would improve sprint and throw performances and that preparatory activities that can cause post-activation potentiation should be used to improve athletic performance.

Resumo A potencialização pós-ativação é um fenômeno fisiológico capaz de aumentar o desempenho muscular durante exercícios de alta intensidade. Para induzir a potencialização pós-ativação, atividades de curta duração com força máxima ou potência muscular são realizadas minutos antes da atividade principal na tentativa de aumentar o desempenho. O objetivo deste estudo foi avaliar as publicações anteriores sobre os efeitos da potencialização pós-ativação sobre o desempenho no atletismo. Esta revisão sistemática utilizou os bancos de dados Scielo, Pubmed e SportDiscus com os seguintes termos de pesquisa juntos ou separados: post-activation potentiation, exercise, athletics, track and field, sprint, long jump, triple jump, high jump, shot put, javelin throw, hammer throw e discus throw. A revisão evidenciou que a realização de agachamentos, saltos e sprints, antes da atividade principal, desencadeia o estado de potencialização, que então aumenta o desempenho de sprints e lançamentos, e que atividades preparatórias que causam potencialização pós-ativação podem ser utilizadas para aumentar o desempenho no atletismo.

Effects of continuous vs interval exercise training on oxygen uptake efficiency slope in patients with coronary artery disease

The oxygen uptake efficiency slope (OUES) is a submaximal index incorporating cardiovascular, peripheral, and pulmonary factors that determine the ventilatory response to exercise. The purpose of this study was to evaluate the effects of continuous exercise training and interval exercise training on the OUES in patients with coronary artery disease. Thirty-five patients (59.3±1.8 years old; 28 men, 7 women) with coronary artery disease were randomly divided into two groups: continuous exercise training (n=18) and interval exercise training (n=17). All patients performed graded exercise tests with respiratory gas analysis before and 3 months after the exercise-training program to determine ventilatory anaerobic threshold (VAT), respiratory compensation point, and peak oxygen consumption (peak VO2). The OUES was assessed based on data from the second minute of exercise until exhaustion by calculating the slope of the linear relation between oxygen uptake and the logarithm of total ventilation. After the interventions, both groups showed increased aerobic fitness (P<0.05). In addition, both the continuous exercise and interval exercise training groups demonstrated an increase in OUES (P<0.05). Significant associations were observed in both groups: 1) continuous exercise training (OUES and peak VO2 r=0.57; OUES and VO2 VAT r=0.57); 2) interval exercise training (OUES and peak VO2 r=0.80; OUES and VO2 VAT r=0.67). Continuous and interval exercise training resulted in a similar increase in OUES among patients with coronary artery disease. These findings suggest that improvements in OUES among CAD patients after aerobic exercise training may be dependent on peripheral and central mechanisms.

Background: Decreases in function of the immune system with age contribute to the increase the risk of infectious diseases especially the upper respiratory tract. On the other hand, physical activity has been widely recommended for health. However, more studies are needed to support the benefit effect of exercise on immune system in elderly. Aim: To evaluate the effect of the hydrogymnastics on the serum level of immunoglobulin A (IgA) in elderly women. Methods: Twenty-six participants were randomly assigned to an experimental (n: 16) or a control group (n: 10). IgA concentrations were determined by nephelometry (BN2 Analyzer, Dade Behring). The hydrogymnastics training protocol was performed 5 times a week during 12 weeks. The intensity of the aerobic exercise was 50-60% of the maximum heart rate monitored by telemetry (Polar-FT7). Results: No significant differences (p: 0.797) resulted by ANOVA on serum IgA levels; the percentage of change in experimental group was Δ% = -6.7 mg/dL compared to the control group, Δ%= -7.4 mg/dL. Conclusion: After three months of hydrogymnastics the IgA level did not show significant change on elderly women; However, positive improvement in percentage of change Δ% was found.

Introducción: La disminución de la función del sistema inmune con la edad es asociada a la incidencia de enfermedades infecciosas del tracto respiratorio superior; por otro lado, el ejercicio físico ha sido ampliamente recomendado para la salud. Sin embargo se requiere aún fundamentar con mayor exactitud los efectos del ejercicio físico en el sistema inmunológico en adultos mayores. Objetivo: Evaluar el efecto de un programa de hidrogimnasia sobre la concentración sérica de Inmunoglobulina A (IgA) en adultas mayores. Métodos: 26 participantes fueron asignadas aleatoriamente a un grupo experimental (n: 16) y un grupo control (n: 10). Se determinó la concentración sérica de IgA por nefelometría (BN2 Analyser, DADE Behring). Las sesiones de hidrogimnasia se realizaron cinco veces por semana durante 12 semanas; el ejercicio fue aeróbico a una intensidad de 50-60% de la frecuencia cardíaca máxima controlada por telemetría (Polar-FT7). Resultados: Se utilizó la prueba de ANOVA, indicando no interacción significativa (p: 0,797). El porcentaje de cambio resultó de Δ% = -6,7 mg/dL del grupo experimental en comparación con el grupo control Δ% = -7,4 mg/dL. Conclusiones: Un programa de tres meses de hidrogimnasia en mujeres no mejora significativamente los niveles de IgA. Sin embargo, los datos refieren una mejora positiva el porcentaje de cambio A%.
