Impact of Perceived Dorsiflexion and Plantarflexion in the Squat and Countermovement Jumps

Muscles
Muscular strength plays a crucial role in sports performance and is often evaluated using vertical jump tests such as the Squat Jump (SJ) and Countermovement Jump (CMJ). Measurements based on flight time (FT) assume that takeoff and landing postures are identical, yet differences in ankle position can introduce systematic errors.
