【摘要】：目的探討利用自行下體負壓訓練器鍛煉后心血管功能及下體負壓耐力的變化 ,為其應用提供實驗依據(jù)。方法 1 2名健康男性被試者隨機分為兩組 ,分別在進氣閥門完全關(guān)閉 (A組 )、進氣閥門打開至峰值負壓為 - 30mmHg(B組 )兩種狀態(tài)下進行鍛煉。A組鍛煉持續(xù)時間為 5d ,3min/d ,分別于鍛煉前、鍛煉 3、5d后進行心臟泵血功能及頭高位傾斜檢查 ,進行短程心率變異性分析 ,鍛煉前后行下體負壓耐力檢查。B組鍛煉持續(xù)時間為 1 0d ,5min/d ,分別于鍛煉前、鍛煉 5、8、1 0d后進行各項檢查 ,檢查項目與A組相同。結(jié)果A組鍛煉后 ,心臟泵血功能顯著降低 ,下體負壓耐力顯著升高。B組心臟泵血功能則在鍛煉 8d后顯著增強 ,下體負壓耐力也顯著提高。結(jié)論利用自行下體負壓訓練器進行鍛煉 ,可以顯著提高下體負壓耐力 ,但訓練方案不同心血管功能的改變也不同。
[Abstract]:Objective to explore the changes of cardiovascular function and lower body negative pressure tolerance after exercise with self-body negative pressure training device and to provide experimental evidence for its application. Methods Twelve healthy male subjects were randomly divided into two groups. When the intake valve was completely closed (group A) and the valve opened to a peak negative pressure of -30mmHg (group B), the duration of exercise in group A was 5 days to 3 min / d. Before and after 3 to 5 days of exercise, the heart pump function and head tilt were examined, and the heart rate variability was analyzed. Before and after exercise, the exercise duration of group B was 10 days and 5 min / d, respectively, before and after exercise, and the duration of exercise in group B was 10 days and 5 min / d, respectively, before and after exercise. After 5 days of exercise, the items were the same as group A. Results after exercise, the cardiac pump function in group A was significantly decreased, and the lower body negative pressure tolerance was significantly increased. In group B, the cardiac pump function was significantly enhanced after 8 days exercise, and the lower body negative pressure tolerance was also significantly increased. Conclusion the exercise can improve the endurance of lower body negative pressure significantly, but the changes of cardiovascular function in different training schemes are different.
