| Popis: | This study used cross-sectional and longitudinal training research designs to determine if (a) exercise hyperemia is enhanced in exercise-trained forearms and (b) sympathetic vasoconstriction of the trained forearm is attenuated (sympatholysis) during handgrip exercise. In the cross-sectional comparison, 10 rock climbers, 10 runners, 10 controls participated while the longitudinal training study examined vascular responsiveness in six untrained men before and after 6 weeks of handgrip training. Mean blood velocity, brachial artery diameter, heart rate, and systemic blood pressure were measured at rest, during a cold pressor test (CPT), dynamic handgrip exercise at 30% MVC with and without CPT, and during reactive hyperemia. During the resting CPT, forearm blood flow (FBF) decreased less (P |
