Chronic Grape Extract in Crosstraining Athletes: A Randomized Crossover Trial

Overview

The aim of this study is to investigate the effect of cronic GSE intake in crosstraining may have a favorable impact on biochemical markers, recovery, and performance.

Supplementation with certain antioxidant nutrients is a feasible strategy to accelerate recovery from fatigue and prevent exercise-induced oxidative damage. Grape seed extract (GSE) contains flavonoids such as proanthocyanidins, which are potent antioxidants with numerous health benefits. Therefore, optimizing the recovery process after training is essential for athletes engaged in strength and power sports who aim to enhance performance. Thirty trained CrossFit athletes consumed grape seed extract or a placebo for one week. The training session consisted of a 12-minute strength block, a 13-minute metabolic conditioning (MetCon), and a final 15-minute MetCon. The Rating of Perceived Exertion (RPE), Gastrointestinal Distress Score (GDS), blood pressure 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.
