Loading strategies for countermovement jump: an exploratory comparison of modality and load.

ABSTRACT:

Background

Vertical jump ability is an important indicator for assessing lower-limb explosive power. Loaded jump training, using either peripheral (barbell) or centralized (weighted vest) loading, enhances jump performance through neuromuscular adaptation. However, it's unclear how these modalities (barbell vs. weighted vest), particularly across different external load magnitudes (30%, 40%, 50% of body mass (BM)), affect jump mechanics, postural stability, and motor control. This pilot study aimed to examine how load type and magnitude influence performance, posture control, and kinetics during countermovement jumps (CMJ).

Methods

Seventeen trained males (age 20.2 ± 3.2 yrs; body mass 72.3 ± 7.3 kg) performed CMJ under two loading strategies (weighted vest, barbell; randomi
