Immediate Effect of Mini-Trampoline Jumping On Balance Performance

Purpose: The purpose of this study was to investigate the immediate effect of mini trampoline jumping on dynamic balance. Methods: Twenty-one 40 5th Annual Student Research Symposium recreationally trained individuals volunteered to participate in two days of testing. On familiarization, day participants were randomly assigned a testing condition of either trampoline group (TG) or control group (CG). Anthropometrics were measured followed by a dynamic warm-up and participants were familiarized with the Biodex Balance System SD and mini-trampoline protocol, which consisted of counter movement vertical jumps (CMVJ). On day two, participants completed the dynamic warm-up and completed the balance protocol. Anterior-posterior (AP), medial-lateral (ML), and overall stability index was recorded and used for analysis. The TG completed six maximal CMVJ on the trampoline and the CG rested for 20 seconds. Immediately after either jumping or resting, participant’s balance was reassessed. A 2x2 mixed factor ANOVA was used to analyze group and time effects. Results: There were no significant interactions between time and group for overall (p=0.28), AP (p=0.63), and ML (p=0.097) dynamic balance. There was no significant time (p= \u3e0.05) or group (p= \u3e0.05) effect for overall, AP, and ML dynamic balance. Conclusion: The results show that there were no effects of trampoline jumping on balance performance. The amount of jumps performed on the trampoline was not sufficient to cause an increase or decrease in balance performance. Participants balance results in the TG may have shown a decrease in balance had they jumped on the trampoline longer than the six maximal CMVJ possibility due to fatigue
