BackgroundNo studies were observed optimal intensity loads for the muscle power performance during prone bench pull exercise in Brazilian Jiu-Jitsu athletes (BJJ) and this exercise is more similar with grip technics.PurposeTo identify the optimal intensity for the muscle power performance variables during PBP exercise in BJJ athletes.MethodsFifteen athletes (25.5 ± 4.9 years; 65.6 ± 12.2 kg; 177.5 ± 4.7 cm) performed PBP at 30, 40, 50 and 60% of one repetition maximum (1RM) in a random order. The mean power (MP), mean velocity (MV), mean propulsive power (MPP) and mean propulsive velocity (MPV) were determined by measuring the barbell displacement by a linear encoder.ResultsIn all power performance variables, higher power output was observed at 40 and 50% 1RM when compared to 30 and 60% 1RM (MP: F = 29.07; p < 0.001; MV: F = 40.80; p < 0.001; MPP: F = 53.69; p = 0.003; MPV: F = 166.2; p > 0.001). Additionally, it was observed higher MPP at 50% 1RM when compared to 40% 1RM (F = 55.23; p < 0.001). The polynomial adjustment indicated that the optimal intensity load for producing highest power performance ranged from 45 to 50% 1RM (R 2 = 0.938–0.989) across all variables.ConclusionThe loads between 45 and 50% 1RM produced the optimal muscle power performance during PBP exercise in BJJ athletes. |
