The Acute Effects of Mini-Trampoline Jumping On Jump Performance in Recreationally Trained Individuals

SMSU Event Center BC

The purpose of our investigation was to determine the acute effects of jumping on a minitrampoline to improve vertical jump performance. Methods: Twenty-one recreationally trained college students volunteered for two testing days. Day one, participants signed the IRB approved informed consent and were randomized into one of two groups, control group (CG) or trampoline group (TG). Participants completed a dynamic warm up and were familiarized with all countermovement vertical jumps (CMVJ) procedures. On day two, participants completed dynamic warm-up followed by three pre CMVJ’s. The TG then completed six CMVJ on the trampoline as high as possible whereas the CG rested for 20s before having to immediately complete post CMVJ’s and were reassessed every minute up to 5mins. A group by time mixed factor ANOVA was used to compare group and times differences for each dependent variable. Results: There was no significance (p>0.05) interaction of time and groups for all dependent variable. There was no significant (p>0.05) effect of time for peak force, peak velocity, rate of fore development, and no significant (p>0.05) group effect for all the variables. However, there was a significant (p<0.001) time effect for vertical jump height, where baseline condition was significantly (p<0.05) less than all other time points. Conclusion: These results suggest that although no group differences were found, there was an increased VJH from baseline measures, indicating a learning effect over time. Incorporating the mini-trampoline into an individual’s daily routine will not hinder performance and may have similar effects as another form of warmup
