Volleyball Players' jump power may get a delayed boost from isometric exercise
NCT ID NCT07483931
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a brief, intense isometric exercise could improve jump performance in highly trained male volleyball players several hours later. Fourteen players did either the isometric exercise or a standard warm-up, and their jump height was measured before, 6 hours after, and 30 hours after. The goal was to see if the isometric activity caused a delayed performance boost, which could help athletes plan training and competition warm-ups.
