探討不同加壓部位對有氧運動血流動力學之影響

本研究目的為探討不同加壓部位對3分鐘低強度橢圓機運動後收縮壓、舒張壓、心跳率、雙產物（double product, DP）和運動自覺量表（rating of perceived exertion, RPE）之影響。以11名大學健康男性受試者進行了一次共3回合低強度橢圓機運動（每回合3分鐘），中間休息10分鐘，第1回合無加壓（non-occlusion, NO）；第2回合下肢加壓（lower limbs occlusion, LLO）；第3回合四肢加壓（four limbs occlusion, FLO）。第2、3回合加壓壓力皆為70%收縮壓。以重複量數二因子變異數分析分別考驗不同實驗處理（NO、LLO、FLO）與不同時段（運動前、運動後）之收縮壓、舒張壓、心跳率和雙產物變化的差異情形，以單因子變異數分析考驗不同實驗處理（NO、LLO、FLO）運動後之RPE值變化的差異情形。結果顯示：1.本實驗處理（NO、LLO、FLO）之收縮壓、舒張壓、心跳率和雙產物皆無顯著差異。2.不論是NO、LLO或FLO，運動後比運動前收縮壓、舒張壓、心跳率和雙產物皆有顯著增加。3.RPE值隨著加壓範圍增加（NO→LLO→FLO）而增，LLO和FLO顯著高於NO。本研究結論：3分鐘低強度有氧運動（橢圓機運動）結合下肢或四肢低加壓訓練，無法造成收縮壓、舒張壓、心跳率和雙產物有顯著差異；加壓訓練會增加自覺用力程度的感受。建議未來研究可針對四肢加壓訓練，搭配較高壓力或較長運動時間進一部探討對血流動力學之影響。

The purpose of the study was to compare the hemodynamic response and the rating of perceived exertion (RPE) during elliptical exercise at low intensity (non-occlusion, NO), low intensity with lower limbs occlusion (LLO) and four limbs occlusion (FLO) in health college male subjects. Eleven men performed trial which comprised three bouts of elliptical exercise each separated by a ten-minutes rest period. The initial bout was a three- minutes light-intensity elliptical exercise. The second bout was a three-minutes light-intensity elliptical exercise with lower limbs occlusion (70% resting systolic blood pressure, RSBP). The third bout was a three-minutes light-intensity elliptical exercise with four limbs occlusion (70% RSBP). All hemodynamic data were analyzed with a two-factor repeated measures ANOVA. The RPE values were analyzed by using one-way ANOVA to test the differences among the groups. The results showed that there were no significant differences in heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and double product (DP). The HR, SBP, DBP and DP after exercise in the groups (NO, LLO, FLO) all significantly increased than those at pre-exercise. The RPE value after exercise increased with the increase of the occlusion range; FLO and LLO were significantly greater than NO. In conclusion, three-minutes light-intensity aerobic exercise combined with lower limbs occlusion or four limbs occlusion cannot cause significant differences in HR, SBP, DBP and DP. Aerobic exercise combined with occlusion training increased the feeling of perceived exertion. Further studies could investigate the effects of FLO combined with higher pressure or longer duration on hemodynamic response.
