Abstract
Inspiratory muscle fatigue (IMF) may limit exercise performance. It has been reported that IMF occurs after various exercises; however, it remains unclear whether IMF occurs after tennis singles match play. The purpose of this study was to test whether tennis singles match play induced IMF. Nine female college tennis players participated in this study. The players were paired in accordance with their skill level, and then played a singles match for an effective playing time (EPT) of 20 minutes. A portable autospirometer was used to measure the maximal inspiratory pressure (MIP) before and immediately after the match as an index of IMF. Heart rate and perceptual measurements were recorded after every 2.5 minutes of effective playing time. The total match duration in this study was 96 ± 8 minutes. Post-match MIP was significantly lower than pre-match MIP (103 ± 21 cmH 2 O vs. 92 ± 22 cmH 2 O, p < 0.05, effect size = 0.47), and the magnitude of the decrease in MIP was 10.0 ± 9.7%. The present results show that IMF occurs after tennis singles match play in females.
吸气肌疲劳(IMF)可能会限制运动表现。据报道,IMF发生在各种演习之后;然而,目前尚不清楚IMF是否发生在网球单打比赛之后。本研究的目的是测试网球单打比赛是否会诱发IMF。9名女大学生网球运动员参与了这项研究。选手按照技术水平进行配对,然后进行单打比赛,有效比赛时间为20分钟。采用便携式自呼吸计测量比赛前后最大吸气压(MIP)作为IMF指标。在每2.5分钟的有效游戏时间后记录心率和知觉测量。本研究的总匹配时间为96±8分钟。配对后MIP显著低于配对前MIP(103±21 cmh2o vs 92±22 cmh2o, p < 0.05,效应量= 0.47),MIP下降幅度为10.0±9.7%。目前的研究结果表明,女性网球单打比赛后会出现IMF。
