Acute Effects of Isometric Conditioning Activity with Different Set Volumes on Countermovement Jump Performance in Highly Trained Male Volleyball Players

Original language description

Background: This study aimed to evaluate the impact of different set volumes and durations of isometric conditioning activity (ICA) (a single 9 s set vs. three 9 s sets, totaling 27 s) on countermovement jump (CMJ) performance in highly trained male volleyball players. Understanding these effects is essential for optimizing warm-up protocols, particularly before competitions or high-intensity training sessions, to maximize performance outcomes. Methods: The 14 participants completed three conditions: one set of ICA (9 s) and three sets of ICA (27 s), each involving maximal isometric contractions in the half-back squat position, as well as a control condition without ICA. Approximately 3 min pre-ICA and at 3, 6, and 9 min post-ICA, the CMJ performance was assessed. Results: The results showed a significant interaction between CMJ height (p = 0.002) and relative peak power (p = 0.004) with the three-set condition. Post hoc comparisons indicated a significant increase in CMJ height at 3 min (p = 0.018; effect size [ES]: 0.868) and 6 min (p = 0.044; ES: 0.808), and a relative peak power output at 3 min (p = 0.005; ES: 0.874) and 6 min (p = 0.034; ES: 0.745) post-ICA compared to pre-ICA. No significant interactions or main effects were found for the modified reactive strength index or CMJ contraction time. Conclusions: The findings suggest that a three-set ICA with a total duration of 27 s may acutely improve CMJ height and relative peak power output in highly trained volleyball players.
