The effect of acute fatigue on reactive strength index in modern dancers
… female, 4 male) participated in this study. Two force plates were utilized to record the force-time data during drop jumps (DJ) before and after an acute, fatiguing protocol. Dancers performed a 5-10 minute self-selected warm up followed by 3-5 practice trials of DJs onto the force plates. Three …

Can changing running shoes immediately reduce the risk of tibial stress fractures?
… The test protocol utilized 3D motion capture, force plates, and EMG. The findings of the current study suggest that strike pattern and foot alignment rather than shoes are the determining factors in eliminating risk factors for TSF. Future works should involve fatigue studies and gait …

An experimental comparison of hitting mechanics in softball
… of the bat to determine bat velocity, while two force plates measured the transfer of weight as nine softball players swung a bat twenty times- ten times with a ball on the tee and ten times with a ball off of the tee. Although it was found that the two hitting models had statistically different …

THE ACUTE AND CHRONIC EFFECTS OF HIGHLY CUSHIONED SHOES ON LOADING CHARACTERISTICS IN RECREATIONAL RUNNERS
… HCS intervention on running-related impact forces in adult recreational runners. We hypothesized HCS would result in altered force attenuation compared to standard cushioned shoes (SCS) at baseline. After 4-weeks, we speculated differences would not be attenuated. Twenty-nine healthy runners …
