The dynamic strength index (DSI) is a useful tool to assess an athlete's capacity effectively use maximum during tasks. Although DSI traditionally calculated based on peak forces, the ability express force over time (i.e., impulse) better predictor of performance. purpose this study was investigate association between (fDSI) and impulse (iDSI). Nineteen female collegiate lacrosse players perfor...
Objective: Hypertensive nephroangiosclerosis (HN) represents the second most common cause of chronic kidney disease. Kidney damage secondary to high blood pressure favors appearance serum and urinary changes, but also imaging, highlighted by ultrasonography (B-mode, Doppler, Acoustic Radiation Force Impulse Elastography). Elastography (ARFI) a new imagistic method which characterizes renal stif...
Despite the fact that soccer is one of the most popular sports in the world, little attention has been paid to this game scientifically which could otherwise provide a broad range of interesting outcomes. Sport equipment has a significant effect on how a game is played. Different features of the soccer ball such as its size, structure, weight and potential incoming pressure also affect the natu...
Overground sprint studies have shown the importance of net horizontal ground reaction force impulse (IMPH) for acceleration performance, but only investigated one or two steps over the acceleration phase, and not in elite sprinters. The main aim of this study was to distinguish between propulsive (IMPH+) and braking (IMPH-) components of the IMPH and seek whether, for an expected higher IMPH, f...
