本研究考察了30名女性（实验组n= 15,21 +/-4岁，平均+/-SD）进行1分钟单腿站立（SOLEC）平衡测试（n= 15,22 +/-4岁，对照组n= 15,22 +/-4岁）后，平衡测试练习对心肺变化的影响。每日练习2周前后进行平衡试验，测量血压（BP）、心率（HR）、分钟通气量（VE）、呼吸频率（RR）、潮气量（VT）、呼气时间（Te）、吸气时间（Ti）、摄氧量（VO2）。实验组每天进行15分钟的平衡测试练习。相比之下，对照组被要求不做任何平衡测试的特殊练习。在实验组和对照组中，SOLEC诱导BP、HR、VE、RR和VO2显著升高，Te和Ti显著降低。实验结束后，实验组的平衡时间显著增加(P
The present study examined the effects of practice of a balance test on cardiorespiratory changes in response to a 1-min balance test performed by standing on one leg with eyes closed (SOLEC) in 30 females (n=15, 21+/-4 years, mean+/-SD, for the experimental group; n=15, 22+/-4 years for the control group). Blood pressure (BP), heart rate (HR), minute ventilation (VE), respiratory rate (RR), tidal volume (VT), expiratory duration (Te), inspiratory duration (Ti), and oxygen uptake (VO2) were measured during the balance test before and after 2 wk of daily practice. The experimental group was given a daily 15-min practice session for the balance test. In contrast, the control group was instructed not to do any special practice for the balance test. In both the experimental and control groups, SOLEC induced significant increases in BP, HR, VE, RR, and VO2, and decreases in Te and Ti. Following the practice sessions, the balance time increased significantly in the experimental group (P
