Summary

The aim of this study is to investigate the effect of acute phenylcapsaicin intake during a cross-training session on perceived exertion, performance, and recovery in cross-training athletes.

Detailed description

Capsaicin appears to enhance athletic performance by reducing perceived effort, increasing mechanical performance (e.g., total volume load), and decreasing muscle damage. Given the close relationship between the metabolic and physiological responses of cross-training and supplementation with Phenylcapsaicin (PC), it could be expected that consuming capsaicin during cross-training would have a favorable impact on perceived effort, recovery, and performance. 25 women and 24 men trained in CrossFit consumed either Phenylcapsaicin (PC) or a placebo during a CrossFit class, which consisted of a 16-minute weightlifting segment and a 15-minute WOD. Both the Rating of Perceived Exertion (RPE) and the Perceived Recovery Status scale (RPS) were administered at the beginning of the session and at the end of each segment of the CrossFit session. DOMS was assessed using a visual analog scale at 24 and 48 hours after the CrossFit session.
