本年度計劃的目的在於探討不同 PRP 訓練頻率的訓練效果和神經肌肉特性的差異情形；本研究以 20 位體育系男學生隨機分派進行為期十週、每週三次相同負荷之低頻(0.5Hz)和高頻(2.5Hz)的 PRP 訓練，並在 PRP 訓練前中後進行各項訓練效果和神經肌肉特性測試。結果發現(一)低頻 PRP 訓練須經五週後才會促使立定三次跳、垂直跳、助跑跳、30 公尺快跑具顯著的進步(p<.05)；(二)高頻 PRP 訓練五週後 會先使立定三次跳、垂直跳、助跑跳、深跳能力降低，但在五週至十週時才會進步地非常顯著 (p<.05)；且十週訓練能顯著增進 30 公尺快跑、負重半蹲 1RM、動態肌力和爆發力(p<.05)；(三)高頻 PRP 訓練在深跳、30 公尺的訓練效果顯著高於低頻 PRP 訓練(p<.05)，但低頻 PRP 訓練在負重半蹲 1RM的訓練效果則較佳。(四)十週高頻 PRP 訓練會顯著降低Hmax/Mmax(p<.05)，但 T-reflex抗疲勞值則顯著的增大(p<.05)；顯示高頻 PRP 訓練會減低 a運動神經終池興奮性和有助於提高肌梭的耐受性。因此，本研究證實 PRP 高頻訓練具有較佳的訓練效，並能促使週邊反射路徑中的運動神經元終池和肌梭等部位的適應性；故運動神經路徑和感覺器均會受 PRP 高頻訓練的影響，進而使肌力和爆發力具顯著性的提昇。
The purpose of this study was to compare the difference between low frequency (Low-PRP) and high frequency (High-PRP) PRP training on training effect and neuromuscular function. 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.
