Purpose The purpose of this study was to investigate and compare acute responses of various combined weight and pneumatic resistance training on peak power, force, velocity and rate of force development during a squat jump.
Method Fifteen healthy young male voluntarily participate in this study. Each subject preformed 3 sets of 1 repetition of squat jump at 20% of 1RM at various percentage of combined weight and pneumatic resistance training (100:0, 90:10, 70:30 and 50:50) using a counterbalance experimental design. Each experiment was separated by 72 hours. Data were presented as mean, and standard deviation. One-way analysis of variance with repeated measures was used to identify a statistical significant. The statistical significance was set at the level 0.05.
Results (1) The average peak velocity value of 50:50 combined weight and pneumatic resistance was significantly higher than that of other combinations (100:0, 90:10 and 70:30) (P<.05). (2) The average peak power, peak force values and rate of force development during squats jump were not differ among conditions.
Conclusion The combined weight and pneumatic 50:50 of resistance training was more effective for enhancing peak velocity during squats jump than that of other ratios. This can be used to improve peak velocity during squat jump in healthy young male.
