# The relationship between physical fitness and drop vertical jump biomechanics in male college basketball players

## TL;DR

This study explores how physical fitness relates to vertical jump biomechanics in male college basketball players.

## Contribution

It identifies specific physical fitness measures that correlate with drop vertical jump biomechanics.

## Key findings

- Health-related fitness tests like sit-ups and core endurance correlate with DVJ biomechanics.
- Ankle and trunk flexibility influence specific joint movements during the jump.
- Fitness assessments may serve as alternatives to traditional biomechanical evaluations.

## Abstract

Studies have shown that vertical jump biomechanics or patterns may be related to physical fitness. This study investigated the relationship between physical fitness and drop vertical jump (DVJ) biomechanics in male college basketball players.

Health-related physical fitness was measured by 20s sit-up, core endurance and flexibility test; whilst athletic-related physical fitness by Y-balance test and dominant extremity single-leg hop distance test. Kinetics and kinematics during DVJ were evaluated by VICON.

Five-level side bridge correlated negatively with angle displacement of hip adduction (p = 0.014) and positively with moment of knee flexion (p = 0.033); 8-level abdominal bridge correlated positively with moment of knee flexion (p = 0.01); ankle dorsiflexion range of motion correlated negatively with mediolateral ground reaction force (p = 0.025), angle displacement of knee flexion (p = 0.004), moment of ankle plantarflexion (p = 0.009), and positively with angle displacement of ankle plantarflexion (p = 0.015); ankle plantarflexion ROM correlated negatively with angle of knee flexion (p = 0.012); trunk flexion ROM correlated negatively with moment of ankle plantarflexion (p = 0.014).

Health-related physical fitness could be the alternatives for DVJ biomechanics assessment.
