The objective of this study was to compare the anthropometric and lower limb power (PMI) variables in a sample of rugby-7 players holding different positions. Twenty-two rugby-7 college players participated; according to the positions occupied on the playing field, they were classified in back and forward. The protocol of seven skin folds of Jackson & Pollock was used to evaluate the percentage of fat; and for the PMI tests vertical jump (CMJ), horizontal jump and triple jump. The T-test for paired samples was adopted, being p < 0.05, to compare the study variables. The results indicated a significant difference between the total mass (p < 0.01), the fat-free mass (p < 0.05), the fat mass (p < 0.01), and the CMJ (p < 0.005) between the groups. It is observed that the anthropometric demands for the forwards are different from the backs, due to the characteristic of the game position, which requires a different physical and morphological configuration.
