Acute Effects of Mini Trampoline Training Session on Leg Stiffness and Reactive Power

The purpose of this study was to evaluate the acute effects of a mini trampoline training session (SuperJump((R))) on leg stiffness and reactive power (RP) while examining its relation to participants ' sex. A total of 20 participants (11 females, age: 24.4 +/- 1.0 yrs; 9 males, age: 27.3 +/- 2.9 yrs) performed continuous jump repetitions (RJs), measured on a force plate, before (PRE) and after (POST) a 30 min Superjump((R)) session. Linear repeated measures mixed models were used to examine the effects of the Superjump((R)) session on the leg stiffness mean (K-MEAN), mean of the best RJs (K-BEST), and RP in relation to sex. Before and after the mini trampoline training session, females showed lower K-MEAN and KBEST values compared with males. Despite the significant (p < 0.002) decreases in RP after the Superjump((R)) session in both males (PRE: 23.1 +/- 6.5 W/kg; POST: 21.2 +/- 6.1 W/kg) and females (PRE: 23.6 +/- 5.5 W/kg; POST: 21.9 +/- 5.3 W/kg), leg stiffness remained unchanged, suggesting a potential protective effect of mini trampoline training on leg stiffness during acute adaptations. These findings suggest that Superjump((R)) training might exert a protective effect on leg stiffness, which prevents acute decreases that are commonly observed in other training modalities. The sex-related differences emerging from the present study emphasize the need for personalized approaches when integrating this innovative training tool into athletes ' regimens.

Automated summary

This study evaluated the acute effects of mini trampoline training on leg stiffness and reactive power, and found that it may have a protective effect on leg stiffness, preventing acute decreases. The sex-related differences emphasized the need for personalized approaches in athletes' training regimens.
