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

Abstract

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.
