OBJECTIVE: Orthostatic intolerance (OI) may occur postexercise in normotensive individuals due to gravitational stress and removal of muscle pump. DESIGN: Six subjects performed 3 maximal bouts of exercise associated with (1) no intervention (CONTROL) (initial trial), (2) with use of lower limb compression garment (TROU), and (3) lower limb exercise (HEEL). SETTING: In each trial, 10 minutes of supine rest was followed by 10 minutes of standing before and immediately after maximal exercise. PARTICIPANTS: All subjects were OI during the CONTROL trial. INTERVENTIONS: In the TROU trial, the compression garment was worn during the supine and standing phases. In the HEEL trial, heel raises were performed every 60 seconds during standing periods. MAIN OUTCOME MEASURES: Systolic blood pressure and heart rate were continuously recorded, and stroke, cardiac output, and total peripheral resistance were estimated (PortAPres, TNO Biomedical Instrumentation, Amsterdam, the Netherlands). Positional changes were compared preexercise and postexercise in CONTROL, TROU, and HEEL via 2-way analysis of variance. RESULTS: All 6 subjects experienced OI in the CONTROL trial, but this was reduced to 2 after the HEEL and 1 after the TROU. Minor increases in systolic blood pressure (CONTROL, 3 +/- 11; TROU, 12 +/- 18; HEEL, 7 +/- 15 mm Hg) and heart rate (CONTROL, 10 +/- 12; TROU, 16 +/- 8; HEEL, 15 +/- 13 beats.min) were observed, but total peripheral resistance did not alter significantly during orthostasis postexercise (CONTROL, 0.462 +/- 0.351; TROU, 0.325 +/- 0.212; HEEL, 0.746 +/- 0.412 medical units). CONCLUSIONS: It seems that simple methods/practices adopted by athletes can have a positive impact on OI. |
