Abstract
Abstract
Background: Post-activation potentiation (PAP) is a physiological phenomenon that acutely improves voluntary muscular performance following a conditioning activity. PAP is usually demonstrated by increased explosive power performance. However, the possibility that acute caffeine consumption might enhance the impact of PAP on subsequent performance has received little consideration. This study assessed how male endurance runners' explosive power performance was affected acutely by caffeine consumption and plyometric conditioning activity.
Methods: In a randomized, counterbalanced, single-blinded design, ten male endurance runners (34.6±7 years) completed three distinct tests and one control condition. They were given either a placebo (PLAC) or 6 mg/kg of caffeine (CAF), and they were asked to complete a countermovement jump (CMJ), standing long jump (SLJ), sprint speed test. Every test was examined following a five-minute postconditioning activity.
Results: The results of the statistical analysis showed that there was a significant difference in the vertical jump height test of the CAF+PAP group compared to the control group (p = 0.006). In the 36.6-meter running speed test, the CAF+PAP group had a significant difference compared to the control group (p = 0.007). Also, there was a significant difference between the CAF group and the control group in the vertical jump test (p = 0.002). And in the 36.6-meter running speed test, the PAP group had a significant difference compared to the control group (p = 0.01). In addition, the standing long jump test was not significant in any of the groups.
Conclusions: The findings of this study imply that acute plyometric stimuli enhance subsequent explosive power performance in male endurance runners and that consuming caffeine amplifies this potentiation.
