Capsaicin, known for its antioxidant and antibacterial properties, may mitigate oxidative stress and inflammation associated with exercise-induced muscle damage (EIMD). This study evaluates the efficacy of capsaicin supplementation in reducing delayed-onset muscle soreness (DOMS) and enhancing strength and power in collegiate male futsal players. A randomized, double-blind, placebo-controlled crossover design was used. Twelve male futsal players participated in three testing sessions: baseline (BL), followed by capsaicin (12 mg) or placebo (PLA), with a 7-day washout period. Participants consumed the supplement 45 min before completing an EIMD protocol of 200 plyometric jumps with a 10% body-weight vest. Metrics including vertical jump height (VJH), pressure pain threshold (PPT), thigh circumference (TCM), and isokinetic and isometric strengths were assessed 48 h post-EIMD. DOMS was measured using a visual analog scale (VAS) at baseline and 12, 24, and 48 h post-EIMD. Capsaicin supplementation significantly improved VJH ( = 0.009), PPT ( = 0.004), and reduced TCM ( = 0.015) compared to baseline, with superior performance in PPT and TCM reduction ( < 0.05). Capsaicin also significantly decreased VAS scores for DOMS immediately, 12, 24, and 48 h post-EIMD ( < 0.001) compared to PLA and BL. No significant differences were found in isokinetic and isometric strength metrics ( > 0.05). Acute capsaicin supplementation can mitigate DOMS and enhance performance markers such as VJH and PPT in collegiate futsal players. Its benefits suggest a viable nutritional strategy for recovery and performance optimization in high-intensity sports.
辣椒素以其抗氧化和抗菌特性而闻名，可能减轻与运动诱导的肌肉损伤（EIMD）相关的氧化应激和炎症。本研究评估补充辣椒素对减轻大学生男子五人制足球运动员延迟性肌肉酸痛（DOMS）以及增强力量和爆发力的效果。采用随机、双盲、安慰剂对照的交叉设计。12名男子五人制足球运动员参加了三个测试阶段：基线期（BL），随后是辣椒素组（12毫克）或安慰剂组（PLA），中间有7天的洗脱期。参与者在完成一项穿着相当于体重10%的背心进行200次增强式跳跃的EIMD方案前45分钟服用补充剂。在EIMD后48小时评估包括垂直跳跃高度（VJH）、压力疼痛阈值（PPT）、大腿围度（TCM）以及等速和等长力量等指标。使用视觉模拟量表（VAS）在基线期以及EIMD后12、24和48小时测量DOMS。与基线相比，补充辣椒素显著提高了VJH（ = 0.009）、PPT（ = 0.004），并减小了TCM（ = 0.015），在PPT降低和TCM减小方面表现更优（ < 0.05）。与安慰剂组和基线期相比，辣椒素在EIMD后即刻、12、24和48小时也显著降低了DOMS的VAS评分（ < 0.001）。在等速和等长力量指标方面未发现显著差异（ > 0.05）。急性补充辣椒素可以减轻大学生五人制足球运动员的DOMS，并增强诸如VJH和PPT等表现指标。其益处表明在高强度运动中是一种可行的营养恢复和表现优化策略。
