Twenty college students participated in the program for 10 weeks. Results reveal that (1) Low-PRP training significantly improved triple jump, vertical jump, approach jump and sprint speed (p<.05). (2) In High-PRP training, triple jump, vertical jump, approach jump and depth jump slightly decreased the first 5-weeks of the training protocol. The second 5-weeks training protocol though showed a significant increase (p<.05). Moreover, sprint speed, 1RM, instantaneous force and power significantly increased after 10-weeks of High-PRP training (p<.05). (3) High-PRP training had a better training effect than Low-PRP training on depth jump and sprint speed (p<.05). (4) High-PRP training induced a significant decrease of Hmax/Mmax ratio, but significantly increased the T-reflex fatigue index (p<.05). The findings suggest that High- PRP training had a better training effect and induced an adaptation of the a-motorneuron pool and muscle spindle. The adaptation of the neuromuscular function is a main contribution to training effect after High-PRP training.49026 bytesapplication/pdfPRP 訓練; 訓練頻率; 神經肌肉特性; 訓練效果PRP training; training frequency; neuromuscular function; training effect.report
