壓力褲對於靜態過重或肥胖女性之運動心肺功能及跑步經濟性影響

研究目的：過去以壓力服飾(compression garments)進行的運動生理研究，對於壓力褲可以幫助運動心肺表現有兩個假設： 1. 改善周邊血液回流 2. 減少肌肉振盪(muscle oscillation)之耗能，但多數研究無法證實上述假設，對於運動心肺功能仍未觀察到顯著的助益。本研究針對坐式生活型態合併過重或肥胖的女性族群，觀察透過壓力褲漸進式壓力設計，能否減少該族群運動過程因肌肉振盪造成的能量損失，進而促進跑步經濟性(running economy)及運動心肺表現。研究方法：12 位體重過重或肥胖、且無規律運動習慣女性，依照平衡次序原則，6 位先穿壓力褲再穿一般運動服飾，另6 位先穿一般運動服飾再穿壓力褲，進行漸增負荷最大量運動測驗(progressive maximal exercise testing)和固定強度運動測驗，分析其心跳率、攝氧量、無氧呼吸閾值(anaerobic threshold)、呼吸代償閾值及跑步經濟性等運動生理參數。結果：穿著壓力褲時的運動最大攝氧量並無顯著上升(p=0.88, ES:0.12)；固定強度下無氧呼吸閾值出現的時間點平均延長 5.13%(p = 0.03, ES: 0.22)；固定強度下運動經濟性平均值變差 2.15%，但無顯著差異。。結論：對於體重過重坐式生活型態女性，穿著壓力褲與否之運動最大攝氧量、無氧呼吸閾值攝氧量、呼吸代償值攝氧量、跑步經濟性皆無顯著差異；穿著壓力褲達無氧呼吸閾值的時間顯著延長，可以改善跑步者的有氧耐力。因此壓力褲對於促進跑步經濟性及運動心肺表現無明顯助益。

Purpose: Previous studies conducted on pressure garments have suggested that compression garments may have positive effects on cardiopulmonary function while performing exercises by improving peripheral venous return and reducing muscle oscillation that may cause energy loss. However, most studies have not been able to prove this hypothesis and concluded that compression has no positive effect on cardiopulmonary function while performing exercises. This study was aimed at determining whether compression garments with a pressure gradient can reduce energy loss caused by muscle oscillation and subsequently promote running economy and cardiopulmonary function in sedentary overweight females. Methods: This study was conducted with a repeated measures design, with the same subjects wearing compression tights or sweatpants for exercise testing, after which the effect of different pants was compared. Twelve overweight females (body mass index ＞24) with a sedentary lifestyle wearing compression tights or conventional running clothing underwent progressive maximal exercise testing and fixed-intensity testing according to the counterbalanced design. We collected and analyzed the exercise parameters, including the heart rate, oxygen uptake, ventilation threshold, respiratory compensation point, and running economy. Results: The maximal oxygen uptake of subjects wearing compression tights did not increase significantly (p = 0.88, ES: 0.12). The average time to reach the ventilation threshold was extended by 5.13% (p = 0.03, ES: 0.22), but exercise economy deteriorated by 2.15% without statistical difference in the fixed-intensity testing. Conclusion: For sedentary and overweight women, wearing compression tights did not improve maximal oxygen uptake, oxygen uptake of anaerobic threshold, oxygen uptake of respiratory compensatory threshold, or running economy, but the time to reach the anaerobic threshold was significantly prolonged that can facilitate the aerobic endurance of runners. Overall, compression tights have no obvious benefits for running economy or cardiopulmonary function.
