Acute Capsaicin Supplementation Improved Resistance Exercise Performance Performed after a High-Intensity Intermittent Running in Resistance-Trained Men
We sought to investigate the acute effects of capsaicin supplementation on the rate of perceived exertion (RPE) and heart rate during high-intensity intermittent exercise (HIIE) and resistance exercise performance executed after HIIE in resistance-trained men. Eleven resistance-trained men completed...

| Sumario: | We sought to investigate the acute effects of capsaicin supplementation on the rate of perceived exertion (RPE) and heart rate during high-intensity intermittent exercise (HIIE) and resistance exercise performance executed after HIIE in resistance-trained men. Eleven resistance-trained men completed 2 randomized, double-blind trials: capsaicin condition or a placebo condition. The concurrent exercise session was composed of a 5-km intermittent run (1:1 effort and passive recovery ratio) and subsequent resistance exercise (4 × 70% of 1RM until muscle failure in the half-squat exercise). Heart rate was recorded during HIIE and after the protocol RPE (0–10 scale) was accessed. The resistance exercise performance was analyzed by the maximum number of repetitions performed for each set and the total volume (repetitions 3 weight lifted). During HIIE, the RPE (capsaicin = 7 ± 1 vs. placebo = 8 ± 1 points, t = -3.674, p = 0.005) and mean heart rate (capsaicin = 153 ± 13 vs. placebo = 158 ± 12 bpm, t = -2.292, p = 0.048) were significantly lower in the capsaicin compared with placebo condition. For subsequent resistance exercise, there was a significant decrease in volume across time (F = 19.889, p< 0.001, η2 = 0.69) with maximal number of repetitions performed in capsaicin than placebo condition (2,077.6 ± 465.2 kg vs. 1,838.9 ± 624.1 kg, p = 0.028, d = 0.43), but the condition vs. set was not significant (F = 0.582, p = 0.632, η2 = 0.06). Acute capsaicin supplementation induced a lower mean heart rate and RPE during HIIE and improved subsequent resistance exercise performance in resistance-trained men. |
