The purpose of this study was to compare the effects of two acute doses of Capsiate (CAP; 6 vs. 12 mg) on upper body resistance exercise performance in trained men.
Using a randomized, crossover and double-blind design, 20 resistance-trained males were supplemented with low-dose CAP (6 mg), high-dose CAP (12 mg) or placebo 45 minutes before exercise. Subjects performed 4 sets of bench press with repetitions to failure at 70% 1 repetition maximum (1RM) and 2 minutes of rest between each set. The ratings of perceived exertion (RPE) and blood lactate were analyzed at baseline and after exercise.
Total weight lifted was greater in the low CAP (2,454.6 ± 448.6 kg) compared to placebo (2,354.7 ± 458.6 kg, = 0.039) and high CAP (2,309.3 ± 428.1 kg, = 0.001). There was no significant difference between conditions for RPE ( = 0.155) and blood lactate ( = 0.434).
In summary, 6 mg CAP increased total weight lifted and repetitions to failure on bench press exercise in trained men, while 12 mg did not present any effect.
本研究旨在比较两种急性剂量的辣椒素（CAP；6毫克与12毫克）对训练有素的男性上身抗阻运动表现的影响。
采用随机、交叉和双盲设计，20名抗阻训练男性在运动前45分钟补充低剂量CAP（6毫克）、高剂量CAP（12毫克）或安慰剂。受试者进行4组卧推，每组以70%的1次最大重复量（1RM）进行至力竭，每组之间休息2分钟。在基线和运动后分析主观用力感觉（RPE）评分和血乳酸水平。
与安慰剂组（2354.7±458.6千克，P = 0.039）和高剂量CAP组（2309.3±428.1千克，P = 0.001）相比，低剂量CAP组的总举重量更大（2454.6±448.6千克）。RPE（P = 0.155）和血乳酸水平（P = 0.434）在各条件之间无显著差异。
总之，6毫克的CAP增加了训练有素的男性卧推运动中的总举重量和至力竭的重复次数，而12毫克则没有任何效果。
