Abstract

KENNEY, W. L. and C. GLENN ARMSTRONG. The effect of aerobic conditioning on venous pooling in the foot. Med. Sci. Sports Exerc., Vol. 19, No. 5, pp. 474-479, 1987. Nineteen fit college-age men were studied using foot (mid-arch) mercury-in-silastic strain gauge plethysmography before and after an 8-wk aerobic conditioning (running) program. Foot volume changes were followed through two maneuvers: A 15-s Trendelenburg procedure (passive leg elevation with subsequent relaxation in the dependent position) and a 15-s dynamic dorsi-flexion/plantar flexion exercise and subsequent relaxation. The conditioning regimen consisted of running 40 min, 3 d · wk-1and resulted in a 10% (P < 0.01) increase in V˙O2max. Following this regimen, subjects exhibited an increased blood volume drainage during the Trendelenburg procedure (mean ΔVT= 3.3 ml · 100 ml-1pre-training, 3.8 ml · 100 ml-1post-training, P < 0.05), but no significant change in ΔVE(2.7 ml · 100 ml-1for all subjects). Muscle pump efficacy, defined as the ratio between ΔVEand ΔVT, did not change (64%). These data suggest that increased aerobic power via weight-bearing exercise training results in an increased foot venous pooling, but does not affect relative muscle pump function. This apparent increase in vascular pooling may be a physical response to the hypervolemia induced by endurance training, aiding in maintaining the constancy of vascular pressures.
