The acute effects of a 10-minute mobility training intervention on countermovement jump and hop test performance

This study investigated the acute effects of a 10-minute mobility training intervention on countermovement jump (CMJ) and hop test (HT) performance, alongside body composition analysis. Twelve healthy, recreationally active females completed pre- and post-intervention tests. Body composition and anthropometric measurements were obtained using a Fit3D ProScanner, while CMJ and HT data were collected via VALD Force Decks. Results indicated statistically significant improvements in CMJ jump height (p=0.008), peak landing force (p=0.040), peak power normalized to body mass (p=0.001), and modified Reactive Strength Index (RSI) (p<0.001) following mobility training. In contrast, the hop test showed a significant increase only in mean peak force (p=0.025), with no significant improvements in mean jump height (p=0.106) or mean RSI (p=0.125). These findings suggest that mobility training acutely enhances performance in long stretch-shortening cycle (SSC) activities like the CMJ by optimizing joint range of motion and muscle preloading. However, its benefits may not extend to short SSC tasks such as the HT, which rely more on tendon stiffness and rapid reactivity. The study highlights the importance of tailoring mobility interventions to the specific demands of performance tasks.
