Effects of practice on cardiorespiratory responses during postural control

Research Article

Abstract

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<0.01). In addition, 2 wk of practice reduced the increases in BP (P<0.01), VE (P<0.05), and RR (P<0.01), and prolonged Te (P<0.01) during the SOLEC test. These results suggest that practice of a postural task affects cardiorespiratory responses to the balance test in addition to postural control.
