LOPES, André Luiz et al. Perfil antropométrico e fisiológico de atletas brasileiros de “rugby”. Rev. Bras. Educ. Fís. Esporte [online]. 2011, vol.25, n.03, pp.387-395. ISSN 1981-4690.

Rugby is a very popular sport around the world and on the rise in Brazil. It is characterized by the existence of two basic tactics positions (forwards and backs), in which athletes have distinguishing functional demands and physical characteristics. Although the international literature presents a number of interesting data about the physiological and anthropometric profile of these athletes, little attention has been spent to Brazilian athletes. This study aimed to verify the performance of 20 amateur rugby players and to compare the aerobic power (VO_2max), anaerobic endurance and isokinetic strength in backs (n = 10) and forwards (n = 10). A computerized gas analyzer (CPX-D - MGC) was used to determine VO₂ and VCO₂. A Wingate test was used to determine the anaerobic endurance. An isokinetic dynamometer (Cybex Norm) was used to measure isokinetic strength. The body composition was evaluated according to five components of ISAK. The data were compared through Student t test for independent samples (p < 0.05). Our results show a significant difference between backs and forwards in the variables VO_2max (47.8 ± 4.5 and 38.8 ± 5.5 ml.kg^-1.min^-1); 2nd ventilatory threshold (38.3 ± 3.0 and 31.6 ± 4.2 ml.kg^-1. min^-1); average power (7.5 ± 0.6 and 6.3 ± 1.1 W.kg^-1); total work (225.7 ± 18.4 and 187.9 ± 31.7 J.kg^-1); body weight (78.5 ± 9.5 and 101.6 ± 12.6 kg); fat mass (24.7 ± 3 , 2 and 29.7 ± 4.6%) and muscle mass (48.7 ± 4.2 and 44.5 ± 3.4%) respectively (p < 0.05). Thus, there are significant differences, related to the tactic position and function, in Rugby athletes. Furthermore our results shows that even at the amateur level athletes, physiological and anthropometric characteristics are similar when compared to professional level players.
