Summary

Youth basketball is a sport that requires high levels of power and speed. Regardless of the competitive level, young athletes undergo rigorous training to enhance their coordination, neuromuscular reactivity, jump height, and sprint speed. Each youth basketball player voluntarily underwent testing at the same sports facility after reading and signing the informed consent document (provided by parents or legal guardians). During the first session, general anthropometric information was collected on all participants (age, weight, and height), followed by an assessment of athletic performance and stability parameters. For the vertical jump performance parameters, the Counter Movement Jump test (CMJ) was used through an optical detecting system. A pressure platform was used to measure ankle stability during the landing phase using a single-leg jump protocol, while acceleration performance was evaluated via a 10-meter sprint test. Subsequently, participants were randomly divided into two groups: an experimental group (EG) and a control group (CG). The EG performed a Drop Jump protocol at the end of warm-up, consisting of three sets of 5 repetitions, with a 3-minute rest period between sets, for a total duration of 8 weeks. At the end of the eight weeks, all measurements regarding the evaluated outcomes (vertical jump height, CMJ, landing ankle stability, and 10-meter sprint) were repeated for both groups.

Drop Jump

Three sets, each consisting of 5 repetitions with 3-minute breaks between sets, to be performed twice a week. During each DJ trial, the participants were asked to perform a maximum vertical jump with their hands at their sides as soon as possible after touching the ground. They were also given 15 seconds to climb back onto the drop and perform another trial.
