Herbal products and supplements use by athletes has increased over the past decade. One such item being polyphenols. These are reported to reduce weight and modify body composition, which could aid athletes in many sports. Therefore, the purpose of the study was to determine the effect of 6 weeks supplementation with carob, a naturally occurring polyphenol, on body composition and aerobic capacity in youth taekwondo athletes. Twenty-three taekwondo athletes (21.9 ± 1.2 years; 1.64 ± 0.03 m; 67.4 ± 17.3 kg;BMI: 22.8 ± 5.5 kg/m) participated in a short-term (6-week) double-blind randomized design parallel fully controlled training study (pre-to-post measurements): Supplemented group (SG), n = 11;placebo group (PG), n = 12. Body composition, aerobic capacity, heart rate and RPE were analyzed before and after 6 weeks of carob rich polyphenol ingestion. Significantly greater decreases in weight were observed for SG and PG (-2.82% and - 0.51%respectively) with differences between groups (p < 0.001). No significant differences were reported in percentage body fat and muscular volume between groups. Our results revealed an improvement of aerobic performance score and RPE with differences between groups. A cute polyphenol supplementation seemed to be effective in reducing body weight and improving aerobic performance in athletes.
在过去的十年中，运动员对草药产品和补充剂的使用有所增加。多酚就是其中之一。据报道，多酚可以减轻体重和改变身体成分，这可以帮助许多运动员在运动中受益。因此，本研究的目的是确定 6 周补充角豆，一种天然存在的多酚，对青年跆拳道运动员的身体成分和有氧能力的影响。23 名跆拳道运动员（21.9±1.2 岁；1.64±0.03 米；67.4±17.3 公斤；BMI：22.8±5.5 公斤/米）参加了一项短期（6 周）双盲随机设计平行完全对照训练研究（前后测量）：补充组（SG），n=11；安慰剂组（PG），n=12。在 6 周富含多酚的角豆摄入前后分析身体成分、有氧能力、心率和 RPE。SG 和 PG 的体重分别显著下降（分别为-2.82%和-0.51%），组间差异有统计学意义（p<0.001）。两组间体脂肪百分比和肌肉量均无显著差异。我们的结果显示，有氧表现评分和 RPE 均有所改善，组间存在差异。急性多酚补充似乎能有效减轻体重，提高运动员的有氧表现。
