Comparison of drop jump force-time profiles of team sport athletes and active controls

Motriz (Online); 27 (), 2021
Abstract Aim: Lower-body non-contact injuries in team sport athletes (TSAs) are associated when absorbing force, during cutting and landing movements due to a lack of eccentric strength and decreased neuromuscular control leading to excessively higher joint forces. Thus, this project aimed to identify i...
