Study 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.

Study Description

The study was a four-groups randomized controlled trial. In the study, the experimental group conducted a 12-week post-activation potentiation combined with lower limb explosive training intervention designed in this study. In contrast, the control group also underwent a 12-week lower limb explosive training intervention, but the warm-up method was conventional warm-up activities. Subjects participated in training intervention programs twice weekly. After the 12-week training program, data collection was completed.

  1. Warm-up content： The experimental group used PAP as a warm-up method and performed pre-stimulation to induce post-activation potentiation. The pre-activation method is back squats. The pre-activation intensity and frequency are 70% 1RM （One-Repetition Maximum） × 3, 80% 1RM × 2, 90% 1RM × 1 respectively, and the interval time is 2 minutes. The control group performed routine warm-up activities.

  2. Explosive strength training content for lower limbs： After completing the warm-up activities, there was a six-minute interval, and then the experimental group and the control group began the same explosive training content of the lower limbs.
