Effects of training in physical fitness and body composition of the brazilian 5-a-side football team / Efectos del entrenamiento en la aptitud física y composición corporal de atletas de fútbol 5 de la selección brasileña

Objective. The present study aimed to analyze the effect of 16 weeks of training on the parameters of physical fitness and body composition in athletes of the Brazilian 5-a-side football team. Method. The sample consisted of six athletes - four outfield players with functional classification B1 and two goalkeepers without visual impairment -, all male, mean age of 27.33 ± 5.5 years. The athletes underwent two evaluations: before and after 16 weeks of training. We measured the levels of cardiorespiratory fitness through the 20m Shuttle Run and the anaerobic parameters through the Rast Test, while the subjects' body composition was assessed by anthropometric technique. Results. Statistically significant (p ≤ 0.05) levels were found for VO2peak before (44.7 ± 4.7 ml.(Kg.min)-1) and after (50.3 ± 3.2ml.(Kg.min)-1), for anaerobic parameters of Medium Power before (442.8 ± 47W) and after (491 ± 72.9W), Low Power before (328.9 ± 26.7W) and after (405.4 ± 79.6W) and for fatigue index before (39.8 ± 10.3%) and after (29.2 ± 12.7%). Conclusion. The 16 weeks of training were enough to show significant improvements in the components of aerobic and anaerobic fitness of the Brazilian 5-a-side football team players; the same effect was not observed in the indicators of body composition(AU)

Objetivo. El presente estudio tiene por objetivo analizar el efecto de 16 semanas de entrenamiento en los parámetros de la condición física y la composición corporal en atletas del equipo de fútbol 5 de la selección brasileña. Método. La muestra estuvo formada por seis atletas, cuatro jugadores de campo con la clasificación funcional B1 y dos porteros sin discapacidad visual, con una media de edad de 27,3 ± 5,5 años. Los atletas realizaron dos evaluaciones: antes y después de 16 semanas de entrenamiento. Se midieron los niveles de la capacidad cardiorrespiratoria a través de la realización del test de Shuttle Run 20m y las variables anaeróbicas a través del Rast Test, mientras que la medición de la composición corporal de los sujetos se realizó mediante la técnica antropométrica doblemente indirecta. Resultados. Se observaron diferencias estadísticamente significativas (p ≤ 0,05) entre los niveles de VO2pico previos (44,7 ± 4,7ml.(kg.min)-1) y posteriores al entrenamiento (50,3 ± 3,2ml.(Kg.min) -1). Los mismos resultados fueron observados en los valores de potencia media (pre = 442,8 ± 47W, post = 491 ± 72,9W), en la potencia mínima (pre = 328,9 ± 26,7W, post = 405,4 ± 79,6W) y en el índice de fatiga (pre = 39,8 ± 10,3 %, post = 29,2 ± 12,7 %). Conclusión. Las 16 semanas de entrenamiento fueron suficientes para demostrar mejoras significativas en la condición física de los jugadores del equipo de fútbol 5 de la selección brasileña, sin embargo, no se obtuvieron los mismos efectos en los indicadores de la composición corporal(AU)

Neuromuscular and metabolic characteristics of elite basketball referees.

AIM: The dynamics of Basketball refereeing has changed and more recently the championships started to use the participation of three referees, but there is still a lack of information about the physical characteristics and performance of the referees. The aim of this study was to characterize the neuromuscular and metabolic performances and body composition of Brazilian elite basketball referees, with a level of national and international refereeing. METHODS: Thirty-seven referees participated in the study (international level N.=17 and national level N.=20). We evaluated anthropometric and body composition variables, among them: height, body mass, body mass index (BMI) and body fat (%); metabolic parameters: lactate at rest and post-exercise; and neuromuscular performance: speed, explosive lower limbs strength, flexibility and aerobic capacity. The main results showed a statistically significant difference in age, in which the international referees were older than the national level (41.94±6.71; 37.30±7.23; P=0.036). RESULTS: There were not significant differences between the levels for neuromuscular and metabolic parameters and body composition. Comparing the results with athletes, the referees showed lower neuromuscular and metabolic parameters and the body composition showed higher body fat than basketball players. CONCLUSION: These data may represent physiological parameters to be considered in the prescription of physical training during the preparation and competition period.
