Background This study aimed to assess the complementary effect of short-term caffeine supplementation along with post-activation potentiation on the fatigue index and anaerobic power of professional Wushu athletes.
Methods For this study, 16 professional athletes from Qom province were randomly selected and divided into five groups: PAP (placebo with PAP), placebo, caffeine with PAP, and caffeine. The consumption of caffeine and placebo was in the form of capsules, so that each person was given (6 mg per kg of weight) 60 minutes before the anaerobic running-based test. The PAP groups consisted of four repetitions of the squat movement with an intensity of 70% of 1RM. All groups performed the anaerobic RAST test in every session with an interval of one week. Analysis of variance with repeated measurements was used to assess the differences between groups.
Results The results of this study showed that the fatigue index was not significantly different among all groups (p = 0.45). The average power in all three post-activation groups showed a significant increase compared to the placebo group (p = 0.001). In the comparison between the intervention groups, it was found that this increase in the caffeine group with post-activation was more than in the other groups (p = 0.001). It was also observed that the peak power was higher only in the caffeine group with post-activation than in the other groups, and the other groups had no significant difference. In relation to the total time of the RAST test, all intervention groups showed a significant decrease compared to the placebo without post-activation (p = 0.001). In the comparison between the peak power, it was found that the increase in the caffeine group with post-activation was more than in the other groups.
Conclusion In general, the combination of PAP and caffeine can improve the performance of Wushu athletes.
