Association Between Visuomotor Skills And The Effects Of Stroboscopic Vision On Depth Jump Performance, Riley Welch
Association Between Visuomotor Skills And The Effects Of Stroboscopic Vision On Depth Jump Performance, Riley Welch
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
The reactive strength index (RSI) is a popularized method of evaluating depth jump performance. Performance in anticipation of ground impact is influenced by the proprioceptive, vestibular, and visuomotor systems through multisensory integration. The contribution of vision to depth jump performance has been studied through use of stroboscopic goggles, but no study has evaluated which visuomotor skills may be a predictor for DJ performance. The purpose of this investigation was to evaluate the association between visuomotor skills and the effects of stroboscopic vision on DJ performance. Participants consisted of 9 female and 13 male college aged adults. DJ performance was evaluated …

Improving The Specificity Of Vertical Stiffness Measurement In Depth Jump Landings, Miles Mercer
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Greater lower extremity stiffness has been shown to increase bilateral jump height through stretch-shortening cycle optimization. Currently, there are two established methods for estimating vertical stiffness (Kvert) of the human body, which is a variant of lower extremity stiffness. The validity of these methods for estimating Kvert in non-cyclical human movements has been questioned recently due to the complex physiological and neuromotor factors that support stiffness regulation in the muscle-tendon complex. The purpose of the present study was to improve the specificity of Kvert measurement using direct derivation of vertical ground reaction force (GRF) and center …
