Randomized trial evaluates neuromuscular performance in military personnel under loading, suggesting implications for physical readiness.

This study aims to quantify how tactical equipment affects jump performance and assess the reliability of related metrics in military personnel.
Eighteen male soldiers performed countermovement jump (CMJ) and countermovement rebound jump (CMRJ) assessments on dual force plates.
Assessments were conducted under unloaded and loaded conditions with standardized tactical equipment weighing 10.6 ± 1.18 kg.
Force–time variables were categorized into strategy, driver, and outcome metrics.
CMJ outcome and driver metrics showed good to excellent reliability under load (ICC ≥ 0.87; CV ≤ 8.4%).
Jump height and modified reactive strength index (mRSI) significantly decreased under loaded conditions (p < 0.05).
Loaded conditions resulted in longer braking and propulsive phase durations during CMJ, indicating a strategy change under load.

Ceniza-Villacastín et al. (2026) studied this question.
