摘要

本研究之目的在探討12 分鐘跑走訓練對心率變異度之影響。本研究是以國防大學96 學年度上學期一年級男生83 名，其中實驗組59 名（平均年齡18.15±.36歲）、控制組24 名（平均年齡18.08±.40 歲）為研究對象。訓練前、後分別對受試者進行安靜仰臥平躺10 分鐘之心率變異度資料收集。本研究以實驗組實施每週3 次為期八週的12 分鐘跑走訓練；而控制組則進行每週2-3 次、每次20-30分鐘軍校規定之體能訓練，包括跑步、引體向上訓練等。研究結果顯示：一、在時域指標方面，實驗組在訓練後之心跳間期平均值(Mn)大於訓練前，且達顯著水準(p＜.05)；而控制組在訓練後之心跳間期平均值(Mn)、相鄰正常心跳間期差值超過50 毫秒的比例PNN50 均大於訓練前，且達顯著水準(p＜.05)。二、在頻域指標方面，實驗組在訓練後之極低頻功率比(nVLFP)下降、高頻功率比(nHFP)上升，且達顯著水準(p＜.05) ；而控制組在訓練後之極低頻功率比(nVLFP)下降、低頻功率(LFP)及高頻功率比(nHFP)上升，且達顯著水準(p＜.05)。三、訓練後，實驗組與控制組兩組間的心率變異度並沒有呈現顯著差異。五、實驗組在訓練後之12 分鐘跑走距離及最大耗氧量均較訓練前增加，且達顯著水準(p＜.05)。本研究結果顯示，每週3 次，經八週12 分鐘跑走訓練後，可以提升心率變異度中副交感神經的活性、增加心肺循環適能中的最大攝氧量。

The purpose of this study was to investigate the effect of 12 minutes walk/run training on heart rate variability (HRV) in fresh cadets. Eighty three male first year cadets at National Defense University were recruited in this study, 59 cadets (mean age, 18.15±.36 years) in the experimental group, 24 cadets (mean age, 18.08±.40 years) in the control group. Ten minutes of electrocardiogram (ECG) data were obtained while subjects rested quietly in the supine position, before and after the training session. The experimental group accepted 12 minutes run/walk training, three times a week for 8-week; the control group accepted general physical fitness training of pull-up and running for 20-30 minutes, and 2 to 3 times a week for 8-week. The results of this study showed that: 1. The experimental group's mean of R-R intervals (Mean) were significantly higher after 12 minutes run/walk training (p＜.05); and the control group's mean of R-R intervals (Mean), percent of R-R intervals differing ＞ 50 ms from the preceding R-R (PNN50) were also significantly higher after 8-week general physical fitness training (p＜.05) in time domain. 2. In frequency domain, both groups had significantly decreased in normalized very low-frequency power (nVLFP), and t significantly increased in normalized high frequency power (nHFP), however, control group also showed a significant increased in low frequency power(LFP)(p＜.05). 3. There were no significant difference in the parameters of HRV between experimental group and control group, after training. 5. The experimental group's 12 minutes walk/run, V02max were significantly higher(p＜.05), after training. Therefore, it can be concluded that: 12 minutes run/walk training, three times a week for 8 weeks is able to increase autonomic nervous system activity, cardiorespiratory fintness, V0_(2)max.
