Explosive jump-based exercise using the stretch-shortening cycle to build power.
PJT refers to structured training programs built around jumping, hopping, or bounding exercises that load and rapidly reverse the stretch-shortening cycle (eccentric-to-concentric transition) to improve explosive force production. It is commonly used to enhance vertical jump height, sprint performance, and change-of-direction ability, and is also studied for tendon stiffness and injury-risk-reduction effects. Programming details (volume, intensity, surface, contact time) vary widely across studies, so effect sizes and 'dose' comparisons should be interpreted with attention to how PJT was operationalised in each trial.
