But the mechanism of PRP training on neuromuscular function is not evident so far. The purpose of this study was to compare difference between traditional resistance training and PRP training on training effect and neuromuscular function. Twenty college students participated traditional weight training and PRP training for 10 weeks. Results reveal that there were significantly improved sprint speed, isotonic force and power after traditional training (p<.05). Traditional training significantly induced acute effect of α-motor neuron pool excitability (p<.05). There were significantly improve jumping performance, sprint speed, isotonic force, instantaneous force and power after PRP training (p<.05). PRP training didn’t significantly induce acute and chronic effect on neuromuscular function (p>.05). The findings suggest that PRP training with 0.5Hz have significant training effect. The mechanisms might result from hypertrophy or/and recruit fast twitch motor units, instead of neuron factor.418564 bytesapplication/pdfPRP 訓練; 神經肌肉特性; 訓練效果PRP training; neuromuscular function; training effectreport
