Summary

This study investigates the acute effects of different aerobic exercise intensities on lower-limb muscle strength and power in elite male youth gymnasts. Aerobic exercise is commonly included in gymnastics training to improve fitness and recovery, but performing aerobic exercise immediately before strength- and power-demanding activities may temporarily influence neuromuscular performance. Eighteen nationally certified male youth gymnasts aged 15 to 18 years participated in a randomized crossover trial. Each participant completed three treadmill-based aerobic exercise conditions on separate days: high-intensity interval training (HIIT), moderate-intensity continuous training (MICT), and low-intensity steady-state exercise (LSD). Muscle strength and power were assessed before and 15 minutes after each exercise condition using validated force-platform tests, including vertical jumps and isometric strength assessment. The results of this study will help clarify how aerobic exercise intensity influences short-term strength and power performance in youth gymnasts and may inform evidence-based decisions on training sequencing and warm-up strategies in gymnastics practice.

What counts as success

Primary outcome measures

Change in countermovement jump height measured by force platform (cm)
Measured over Immediately before and 15 minutes after completion of each intervention session
Change in isometric mid-thigh pull peak force measured by force plate (N)
Measured over Immediately before and 15 minutes after completion of each intervention session
Change in squat jump height measured by force platform (cm)
Measured over Immediately before and 15 minutes after completion of each intervention session
Change in drop jump height measured by force platform (cm)
Measured over Immediately before and 15 minutes after completion of each intervention session

A trial succeeds or fails on its primary outcome, declared in advance. Everything else it reports is secondary by definition.
