摘要


目的:探討坐式橢圓機在不同運動參數下運動經濟性之差異以及與V ̇O_2max的相關。方法:以30名健康成年人 (男、女各15名,年齡23.77±3.69歲、身高168.70±9.97公分、體重65.77±16.87公斤) 為受試對象,受試者先接受跑步機最大攝氧量測驗,在間隔至少24小時之後,依平衡次序原則以三種座椅高度位置 (上肢參與百分比35%、50%、65%) 進行坐式橢圓機漸增負荷 (16 watt、28 watt、41 watt、54 watt、66 watt) 測驗,各負荷以踩踏頻率30 rpm 踩踏3分鐘,記錄每階段最後一分鐘攝氧量 (oxygen intake, V ̇O_2) 、心跳率 (heart rate, HR) 及運動自覺量(rate of perceived exertion, RPE),以不同負荷下的V ̇O_2、HR、RPE除以負荷分別代表攝氧運動經濟性 (EEVO2) 、心跳經濟性 (EEHR) 、自覺量表經濟性 ( (EEVO2、EEHR、EERPE),資料處理以二因子重複量數分析考驗不同負荷、不同上肢參與百分比座椅高度的EEVO2、EEHR、EERPE之差異,並以皮爾森積差相關檢測不同運動參數水準的運動經濟性之效標關聯效度,選定最大攝氧量 (V ̇O_2max)作為效標變項。結果:EEVO2、EEHR、EERPE在不同上肢參與百分比座椅高度無顯著差異,在不同阻力下達顯著差異。隨著阻力提升,運動經濟性有逐漸上升的趨勢,並於踩踏負荷54 watt (50.25±11%V ̇O_2max) 以上趨於穩定。EEHR與最大攝氧量達顯著負相關 (r= -.67~ -.45,, p<.05)。結論:坐式橢圓機的EEVO2、EEHR、EERPE的測量以50%V ̇O_2max(或70%HRmax)以上可以獲得較穩定的測量結果;調整座椅位置不會影響坐式橢圓機的能量消耗情形;EEHR可以有效預測最大攝氧量。

Purpose:: The aim of this study was to investigate exercise economy (EE) in different seat heights of seated elliptical trainer and its relationship with maximal oxygen uptake (V ̇O_2max). Method: :Subjects (N=30) were healthy adults with average age, height and weight of 23.77±3.69 years, 168.70±9.97 cm and 65.77±16.87 kg respectively. To obtain V ̇O_2max, each subject performed a maximal treadmill test. After 24 hours, all subjects were asked to choose one seating height (percent of upper limb involvement 35%、50%、65%) and participate in gradual increasing load test (16 watt, 、28 watt, 、41 watt, 、54 watt, 、66 watt) by seated elliptical trainer with pedaling rate setting up to 30 rpm. V ̇O_2、heart rate (HR) and rate of perceived exertion (RPE) were recorded in the last minute of each level. EEVO2、EEHR、EERPE meaned that V ̇O_2, HR and RPE were divided by load. Data was progressed by two way RM-ANOVA to compare the difference between seating position on EE and load on EE. Result: :In the beginning, EE increased in gradual increasing load and reached stability when it was greater than 54 watt (50.25±11%V ̇O_2max). Furthermore, EEHR and V ̇O_2max reached significant correlation (r= -.67~ -.45, ,p<.05). Conclusion: :EE had stable measurement results as the load was higher than 50%V ̇O_2max (70%HRmax). Changing seating position did not affect energy consumption. EEHR could predict V ̇O_2max efficiently.
