Effect of PAP on Lower Limb Explosive Force in Basketball Players in CHINA

Summary

The phenomenon that high-intensity warm-up activities help improve muscle strength and explosive performance is called post-activation potentiation (PAP), which is a warm-up method that uses high-intensity stimulation to induce the activation of more type II muscle fibers. However, the results of studies exploring the enhancing effect of PAP on lower limb explosive strength are still controversial. In studies with no significant difference, it is believed that there are many factors that affect PAP, such as activation method, activation intensity, recovery time and individual factors, etc., and it is difficult to control during implementation. In addition, traditional warm-up methods such as jogging and stretching have been shown to have limited effectiveness in improving athletes' performance. In the past, there have been many studies on the combination of PAP and lower limb explosive strength, but there are almost no studies on the long-term effects of PAP on the lower limb explosive strength of basketball players. Therefore, this study studies the characteristics of PAP in order to find the best activation scheme for PAP, and then combines the enhancement effect of PAP with the explosive power of the lower limbs to improve the explosive power of the lower limbs of basketball players, and verifies the long-term effect of combining PAP with explosive power training. In order to provide new changes and breakthroughs in the design of physical training for basketball players and improve the sports performance of college male basketball players.

Interventions

BEHAVIORAL

PAP induced at an intensity of 70% 1RM combined with complex training

This group of subjects first performed 3 sets of 70% 1RM squats after a routine warm-up, 3 times per set, with an interval of 2 minutes between sets. The entire process was maintained for 30 minutes, and then after a 6-minute rest, they performed complex training consists of maximum strength training (back squats) and plyometric training (drop Jump). The Intensity \& Repetition of back squats is 80% 1RM × 4, 4 sets, interval time is 2min; rest for 3 minutes. , perform drop jump, intensity \& repetition is 50cm (height) × 10, 4 sets, and the rest time is 2 minutes. Intervention training was conducted twice weekly for 12 weeks,and the intensity is gradually increasing over the 12 weeks.
