Lower Extremity Intersegmental Coordination Changes Across Countermovement Jump Heights [PDF]

, 2021
While jumping is a fundamental movement skill and a key component in the development of specific sport skills, its coordination, especially at submaximal heights, has yet to be studied in detail.

Vertical Jump Height Estimation Using Low-Sampling IMU in Countermovement Jumps: A Feasible Alternative to Motion Capture and Force Platforms

Sensors
Vertical jump height from a countermovement jump is a widespread metric to assess the lower limb functionality. Motion capture systems and force platforms are considered gold standards to estimate vertical jump height; however, their use in ecological ...
