PURPOSE: The purpose of this study was to analyze the effects of different resistance training intensities on blood pressure (BP) and heart rate (HR) responses. METHODS: 12 males and 12 females (19-28 age) participated in the study (5 sessions). On the first day, initial screening, anthropometric measures, cycle ergometer seat height, leg extension/leg curl machine setting, and familiarization with testing procedures were completed. On the second day, one-repetition maximum (1RM) testing was completed in 2 trials for each machine, starting with 10 min warm up on the cycle ergometer. Following general warm up, subjects performed specific warm up at 50% …

Passive and exercise-heat stress have been reported to cause reductions in cerebral blood flow (CBF); however, it is unknown if CBF velocity is different under hot dry and humid conditions. PURPOSE: This project tested the hypothesis that upright rest and exercise-heat stress in hot dry and humid conditions result in similar CBF reductions. METHODS: Seven healthy active (7 day activity: 9887±3564 steps/day; VO2max: 52±10 mL/kg/min) subjects (5M/2F, 24±9y, 171±6cm, 68±7kg) completed a 30 min baseline rest followed by 60 min of exercise at a rate of perceived exertion (RPE) of 12 (between light and somewhat hard) on a …

Walking With Leg Blood Flow Restriction: Wide-Rigid Cuffs Vs. Narrow-Elastic Bands, Sten Stray-Gundersen, Savannah V. Wooten, Hirofumi Tanaka

Blood flow restriction (BFR) training has become a popular form of exercise in recent years. The concept is that light-load exercise with BFR elicits similar adaptations achieved with heavy-load exercise. Walking exercise in combination with pressurized wide-rigid (WR) cuffs has been shown to elicit higher cardiac workload and a vascular dysfunction due presumably to reperfusion injury to the endothelium. In contrast, narrow-elastic (NE) BFR bands may elicit different hemodynamic effects, as the limb is able to increase in diameter with increased blood flow accompanying exercise. PURPOSE: To compare two distinct forms of BFR bands during light-intensity exercise on cardiovascular …
