| Popis: | 96 Passive Repetitive Isokinetic Training (PRI training) is a plyometric-based training method, which can improve the muscle strength and power for athletes. One of the major features is to enhance the consistent muscle isokinetic contraction. The PRI training shows greater EMG activity when compared to the muscle activation during general muscle strengthening programs. This implies greater amount of motor units might be recruited during the PRI training. Previous studies have demonstrated that muscle strength and muscle power significantly increase after the PRI training. It has been speculated that PRI training might induce the different neuromuscular adaptation when compared to the traditional training methods. Reciprocal inhibition is one of the important neuromuscular mechanisms for increasing muscle strength during the early training stage. The purpose of this study is to investigate the differences in reciprocal inhibition, lower extremity isometric muscle strength, and vertical jump after eight-week PRI training. Nine college baseball team players participated in the training group while seven healthy college students joined the control group. The reciprocal inhibition tests included disynaptic inhibition, D1 inhibition, and D2 inhibition. The results showed that: (1) an increase in isometric muscle strength for both groups; (2) no changes in reciprocal inhibition tests; (3) positive correlation between lower extremity isometric muscle strength and D2 inhibition. Many possible factors might result in the insignificant findings in our experiment. The major possibility is the difficulty in detecting the minor changes in the neuromuscular adaptation after training. However, based on the positive correlation between lower extremity isometric muscle strength and D2 inhibition, we speculate that the PRI training might be related to the changes in muscle strength and reciprocal inhibition。 |
