Hemodynamic Responses To Blood Flow Restriction Exercise With Different Types Of Cuffs, Lin-Sheng Chen, Philippe Brosselin Perez Palma, Natalie Mclaurin, Daniela Charry Segura, Francisco Aguilar, Hirofumi Tanaka
International Journal of Exercise Science: Conference Proceedings
While blood flow restriction (BFR) training has gained popularity, the original narrow elastic (NE) design featured in the Kaatsu bands has been gradually replaced by wide-rigid (WR) nylon blood pressure cuffs that are cheaper and easily available. We demonstrated that using WR cuffs resulted in marked increases in blood pressure and myocardial oxygen demand during BFR walking exercise compared with NE bands. Currently, the hemodynamic responses to BFR resistance exercise using different types of cuffs are unknown. PURPOSE: To compare blood pressure and physiological responses before and after BFR resistance exercise with WR cuffs and NE bands. METHODS: …

The correct choice of the acute variables is another important component of a resistance training (RT) session. The combination of intensity and volume is fundamental to determine the dose-response in a RT session and can induce specific metabolic and mechanical stress in the muscle. PURPOSE: The primary purpose of this study was to evaluate acute dose-response of different volume x intensity RT protocols with equated total volume (40 repetitions) during the crunch exercise on muscle thickness, echo-intensity, load lifted, and rating of perceived exertion in recreationally-trained participants. METHODS: Fifteen resistance-trained participants (23±3years, 76.4±6.5kg, 173.3±6.5cm) performed the abdominal crunch exercise …

Creatine monohydrate supplementation is broadly substantiated to elicit both favorable ergogenic and health-associated advantages amidst vast demographics. Nevertheless, its impacts on human cardiovascular outcomes are hitherto undescribed in generally healthy populations. Furthermore, females are largely underrepresented in the ergogenic creatine literature and their potentially differential cardiovascular responses are unknown. PURPOSE: to determine whether young, healthy females would glean discernible hypertrophy and enhanced performance, commensurate to favorable post-resistance training cardiovascular parameters and relative to placebo-matched controls across a four week training timeline. METHODS: Twenty-eight resistance trained women (25.5±6.1 years) were randomly assigned to supplement creatine monohydrate (CRE; 5g creatine monohydrate …

Post-exercise hypotension (PEH) plays an important role in the antihypertensive health benefits of exercise. While it has been shown that resistance exercise is effective at eliciting PEH, commonly consumed sports supplements may attenuate or completely eliminate that response. Caffeine, a popular stimulant, is often consumed prior to exercise. PURPOSE: Determine the effects of pre-workout caffeine supplementation on the PEH response following resistance exercise in adults with above normal blood pressure (BP). METHODS: Participants (n = 7) were recreationally resistance trained men and women with above normal resting BP (SBP > 120 mmHg and/or DBP > 80 mmHg). Following BP screening and maximal …

Previously, our laboratory introduced a regression equation for predicting net kcal consumption of a resistance exercise (RE) bout: Total net kcal = 0.874(height, cm) - 0.596(age, years) - 1.016(fat mass, kg) + 1.638(lean mass, kg) + 2.461(total volume x 10-3) - 110.742 (R2 = 0.773, SEE=28.5 kcal). PURPOSE: The purpose of this study was to validate this regression equation using the same variables as predictors. METHODS: Forty-seven healthy, active subjects (23 men, 24 women, 20-58 yrs, 173.5 ± 10.5 cm, 85.5 ± 19.0 kg, VO2max 36.0 ± 8.4 ml/kg/min) were randomly divided into validation …
