Introduction Ankle and foot injuries are highly prevalent in the US Armed Forces, incurring medical personnel costs for Department of Defense. The purpose this study was to evaluate burden risk factors plantar fasciopathy (PF) Military. Methods Defense Medical Epidemiology Database identified all diagnosed PF cases military service members from 2006 2015. A custom spreadsheet calculated incidence relative between sexes, occupations ranks. Relative injury per demographic category (sex, age,...

The reliability of isokinetic peak torque (PT) has been reported mostly using a short-term (<~10 day) inter-trial testing time frame. However, many studies and programs utilize long-term (several weeks to months) period. Additionally, the methods by which PT value is selected from multiple rep scheme have not well investigated for both absolute performance comparisons. purpose this study was investigate isometric leg extensors with an emphasis on differences among several score selection...

Purpose: This study investigated the effects of flywheel squat training on lower body muscle function adaptations and sport-specific performance in collegiate club water polo players. Methods: Thirteen athletes (5 women, 8 men) performed for 4 weeks. Isokinetic knee extension (KE) peak power (PP) torque (PT), (FPP) mean (FMP), countermovement jump (CMJ), in-water height (WJH) foot speed were assessed at baseline (Pre1), weeks (Pre2), (Post) with first week block being a control period second...

Background Intrinsic foot muscle (IFM) weakness can result in reduced function, making it crucial for clinicians to track IFM strength changes accurately. However, assessing be challenging clinicians, as there is no clinically applicable direct measure of that has been shown reliable and valid with the on ground. Purpose The purpose was investigate intra-rater inter-rater reliability a novel, budget-friendly dynamometer determine its agreement handheld (HHD). researchers also examined...

The intrinsic foot muscles (IFM) are important as they support the medial longitudinal arch of and control deformation during gait, but it is relatively unknown how much demographic morphology affect IFM strength levels. PURPOSE: To determine influence demographics on muscle in healthy individuals. METHODS: Thirty-seven individuals (4 males, 33 females) participated this study. was assessed a hook-lying position. Participants pressed their toes down onto card attached to hanging scale...
