八週不同模式有氧運動訓練對安靜心率變異度的影響
摘要
有氧運動可提升自律神經對心臟的調控能力，但分段實施是否與連續實施具有相同的效果有待釐清。目的：本研究旨在探討八週連續式或分段式有氧運動介入對安靜心率變異度（HRV）的影響。方法：招募20名健康大學男生，平均年齡21.16 ± 0.31歲，身高174.36 ± 1.36公分，體重69.94 ± 2.80公斤，隨機分派至連續式運動組或分段式運動組，進行一週三次，每次30分鐘，為期八週的自選強度跑步運動介入。觀察變項包括安靜心跳率及HRV變項，如平均正常心跳間期、正常心跳間期標準差、總功率、高頻功率、低頻功率及低高頻比等時域及頻域指標，資料以描述統計及混和設計二因子變異數分析處理，統計水準均訂為α=.05。結果：（一）連續組訓練前後的安靜心跳率為71.70 ± 17.21 vs. 75.40 ± 8.22 bpm，分段組為69.90 ± 12.81 vs. 75.70 ± 8.37 bpm，交互作用未達顯著水準（F=.17, p>.05）；（二）模式間的顯著差異，僅於HRV的時域指標－平均正常心跳間期，發現連續組的臥姿測量值明顯比分段組來得長（957.40 ms vs. 833.52 ms, p<.05）；（三）訓練效果的考驗顯示，正常心跳間期標準差的臥姿測量值、總功率的臥姿及站姿測量值，以及高頻功率的臥姿測量值反映訓練前後的顯著差異。結論：八周有氧運動訓練對HRV產生正面影響，而以分段或連續方式實施沒有差異。

Effects of Different Modes of 8-week Aerobic Exercise on Resting Heart Rate Variability
Abstract
Aerobic exercise enhances the regulatory ability of autonomic nervous system to heart. However, if intermittent exercise has the same benefit as continuous exercise requires clarification. Purpose: Investigating the effects of 8-week continuous or intermittent aerobic exercise on resting heart rate variability (HRV). Methods: Twenty healthy male college students were recruited with mean age 21.16 ± 0.31 yr, height 174.36 ± 1.36 cm, and weight 69.94 ± 2.80 kg. Participants were randomly assigned either to continuous group (CG) or intermittent group (IG), and then instructed to complete a 8-week program, in which exercise 3 times a week and 30 minutes self-selected exercise running for every session. Observed variables included resting heart rate (HR) and HRV indicators, such as mean R-R interval, SDNN, total power (TP), high frequency power (HFP), low frequency power (LFP), and low/high frequency ratio (LF/HF). Collected data were analyzed by descriptive statistics and mixed design two-way ANOVA. Significant level was set atα=.05. Results: 1) HR of pre and post training in CG were 71.70 ± 17.21 vs. 75.40 ± 8.22 bpm, and 69.90 ± 12.81 vs. 75.70 ± 8.37 bpm in IG. Significant interaction effect was not observed (F=.17, p>.05); 2) As to the model difference, only a time domain indicator “mean R-R interval” revealed significant difference, showing that the value measured via supine posture in CG was significantly longer than IG (957.40 ms vs. 833.52 ms, p<.05); As to training effect, SDNN (in supine), TP (both in supine and stand), and HFP (in supine) showed significant differences. Conclusions: 8-week aerobic exercise intervention had positive influence on HRV, while whether exercise performed in intermittent or continuous way didn’t induce further differences.
