Background: Multiple sclerosis induces locomotor impairments. The objective was to characterize the effects of Multiple Sclerosis on whole-body angular momentum control during gait initiation.
Methods: Fifteen patients with Multiple Sclerosis with Expanded Disability status scale of 2.
Article Synopsis
- The study examined how different push-off distances affect the maximum height of jumps among CrossFit athletes during countermovement jumps.
- Results indicated a quadratic relationship between push-off distance and jump height, revealing that each athlete has an optimal push-off distance for maximizing their jump.
- Additionally, longer push-off distances increased push-off time and decreased mean vertical external force, affecting overall jump performance by altering joint angles and torque production in the process.
Evidence suggests that whole-body angular momentum (WBAM) is a highly controlled mechanical variable for performing our daily motor activities safely and efficiently. Recent findings have revealed that, compared to young adults, older adults exhibit larger range of WBAM during various motor tasks, such as walking and stepping. However, it remains unclear whether these age-related changes are ascribed to a poorer control of WBAM with age or not.

This study investigated the influence of aging on the segment angular momenta and their contributions to H during stepping. Eighteen old and 15 young healthy adults were instructed to perform a series of stepping at two speed conditions: preferred and as fast as possible.

However, it is not known if and how H is influenced by speed when stepping. This study aimed to investigate the effect on H of increasing speed during step initiation in older adults.
