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: …

Effects Of Pre-Workout Caffeine Supplementation On Post-Exercise Hypotension, Emily E. Latta, Shelby L. Gibbs, Eric J. Jones, Dustin P. Joubert

International Journal of Exercise Science: Conference Proceedings

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 …

Perceived Importance Of Resistance Training In Collegiate Dancers, Kayla Major

Graduate Theses

Dancers are artistic athletes that use their bodies as their instrument. Dance is a sport that requires significant skill and higher levels of fitness. Unfortunately, dancers are not as physically fit as sport athletes. This may not only increase their risk of injury, but also limit their maximum dance performance. Resistance training offers significant physical and psychological health benefits. But, there is very limited research regarding dancers’ resistance training habits. The results of the few studies that exist unanimously suggest that there is no detriment to the aesthetics of dance, rather improvements in dance elements as a result of improved …
