三種體育訓練對睡眠剝奪之大學生心率變異的影響

THE EFFECTS OF THREE PHYSlCAL TRAININGS ON HEART RATE VARlABILI1Y OF THE COLLEGE STUDENTS AFTER SLEEP DEPRNATIO

目的：本研究目的在於探討健康大學生於期中考試熬夜所造成都份睡眠剝奪後，透過「按摩」、「按摩與放鬆訓練」與「瑜珈」等三種不同運動訓練，探討對心臟自律神經系統所產生的生理恢復程度與效果。材料及方法：受試對象為中國文化大學49位學生，男生14位（28.6% ）女生35位（7 1.4%） ，在數量睡眠剝奪（短於四小時睡眠）狀態下，經由三種不同的運動介入，分析其運動前後各5分鐘坐姿心率變異性。結果：研究發現在期中考熬夜過後，安靜時的VLF與LF/HF活性指數顯著下降（P

Objectiv:Heart rate variability (HRV) is an analytic method of evaluating effects in many exercise trainings. The objective of this study is to evaluate the cardiac autonomic nervous function by different physical trainings after quantitative sleep deprivation caused by mid-term examinations. Methods: There were 49 healthy examinees consisting of students of Chinese Culture University. They received two analyses of five minutes HRV in sitting posture before and after three sets of physical training, including 'massage', 'massage and relaxation training' or 'Yoga'. Results:The study showed that the very-low-frequency (VLF, 0.003-0.04Hz)power and the ratio of low-frequency to high-frequency (LF/HF) after sleep deprivation dropped significantly. This meant that sleep deprivation would affect the parasympathetic tones and the sympathetic tones. With the interposition of three different physical exercises to the students of sleep deprivation, it revealed VLF increased significantly. The VLF increased most after the 'massage and relaxation training'. It was followed by 'Yoga' and the last one was 'massage'. Conclusion: The study showed that all the three types of physical training could recover the autonomic function after sleep deprivation. Especially, the low intensity of 'massage and relaxation training' which could increase the parasympathetic tone rapidly and reduce the sympathetic tone at the same time.
