摘要:Purpose The study compared muscle peak power during pneumatic squat exercise with different percentages of load, corresponding to 80%, 100%, and 120% of body mass (BM), in male professional soccer players. Methods The study involved 40 male elite soccer players (25.2 ± 3.6 years; 179.6 ± 6.1 cm; 78.3 ± 5.2 kg; body fat 12.3 ± 3.3%) from a club of the Brazilian first division soccer league participating in national competitions organized by the Brazilian Soccer Confederation. Peak power was assessed by using a pneumatic squat machine (squat power test). The athletes applied different training loads during the squat power test (3 trials with 80% of BM followed by a 5-minute rest to perform attempts with 100% and 120%, respectively). Results The two-way ANOVA yielded main effects for group (F3,26 = 3.08, p Conclusions The results confirm that loads corresponding to 120% of BM during pneumatic squat exercise contribute to greater absolute and relative peak power.
