Regional changes in reactive hyperemic blood flow during exercise training: time-course adaptations.

摘要: Few studies have examined the time-course of localized exercise training on regional blood flow in humans. The study influence handgrip forearm reactive hyperemic and vascular resistance apparently healthy men. Forearm were evaluated, 17 individuals [Age: 22.6 ± 3.5], both arms, at rest following 5 minutes arterial occlusion, using strain gauge plethysmography, prior to (V1) every week thereafter (V2-5) for 4 weeks. Handgrip was performed non-dominant arm d/wk 20 60% maximum voluntary contraction, while dominant served as control. Resting HR, BP, not altered with training. trained strength circumference increased by 14.5% (p = 0.014) 1.56% 0.03), respectively. ANOVA tests revealed an arms visit interaction 0.02) 0.009). Post-hoc comparison demonstrated 0.0013), decreased post-occlusion 0.05), 1st training, no significant changes subsequent visits. results indicate unilateral improvements 1 leveled off study.
