Acute Effects of a Conditioning Activity on Countermovement Jump Performance in Mixed Martial Arts Athletes

Abstract

Objective: The aim of the present study was to verify the acute effect of a conditioning activity on countermovement jump performance in Mixed Martial Arts (MMA) athletes after different recovery intervals. Methods: The sample consisted of 12 male MMA athletes (age 24 ± 3 years; height 175.0 ± 7 cm, body weight 78.5 ± 13 kg). back squat performed in smith machine consisting 2 sets of 5 seconds of maximal voluntary isometric contraction (MVIC) resting 3 minutes between sets. After executed the squat, the volunteers performed five CMJ with rests of 4, 8 or 12 minutes after the conditioning activity. Results: The ANOVA one-way of repeated measures showed a statistically significant difference to jump height in the different intervals tested [F=12.97; p=0.001; ŋp²=0.56]. These differences were identified by Bonferroni's post-hoc in intervals of 8 and 12 minutes concerning Pre moment and in comparison between 4 and 8 minutes. No significant differences were found in compare between 4 minutes and the Pre moment between 4 and 12 minutes (p=0.239) and 8 and 12 minutes (p=1.000). Conclusion: It report that pauses between 8 and 12 minutes were ideas to promote the increase in CMJ performance.
