Music Enhances Motor Cortex Excitability In Physically Active Individuals, Anupama Thapa, Ana Carolina Panhan, Erin Lally, Joosung Kim
International Journal of Exercise Science: Conference Proceedings
Music is often used by exercisers and benefits physical performance. The positive effects of music on physical function are induced by the changes in motor cortex excitability while listening to music. Recent studies reveal that modulation of brain excitability in the hand is increased by music but is likely dependent on the characteristics of music tempo, preference, and the individual’s motivational state. No study has explicitly investigated whether music perceived as motivating for exercise creates changes in motor cortex excitability of the quadriceps. PURPOSE: This randomized crossover study examines the effect of the preferred music on motor cortex excitability …

Body Composition Impacts Jump Performance In D1 Athletes, Veronika Kramarenko, Vipa Bernhardt, Michael D. Oldham, Brian Jones, Ouays Bakcha, Chaehyun Byun, Cheyenne Martinez, Joseph Mcclain, Marshall Tousant
International Journal of Exercise Science: Conference Proceedings
INTRODUCTION: Body composition is critical in athletic performance, influencing metrics such as jump height and force production. Variations in body composition, such as increased lean tissue mass and reduced fat mass, have been identified as strong predictors of superior jump performance due to their positive effects on power-to-weight ratios and reduced injury risk (MacDonald et al., 2013). Lean mass is strongly correlated with improved jump performance, as greater lean mass enhances muscle cross-sectional area and, consequently, the force and power generated during physical activities like countermovement jumps (CMJ) (Stephenson et al., 2015). Low body fat percentages are generally associated with …
