Summary: Crossfit is characterized as a high-intensity and interval exercise that
includes a variety of activities aimed at improving aerobic and anaerobic
endurance, speed, flexibility, agility and motor coordination. The
improvement of these physical capacities is characterized by an increase in
performance, which in turn can also occur with the help of ergogenic
resources. Capsaicin, a natural substance present in red peppers, has been
shown to improve performance in high-intensity activities. The aim of this
study is to evaluate the effect of capsaicin supplementation on Crossfit
performance. It was a double-blind, crossover design, in which participants
received a 12mg dose of capsaicin and placebo in capsules. For performance
evaluation, the Fight Gone Bad benchmark, already known by Crossfit
practitioners, was applied. Variables such as subjective perception of effort
and the scale of physical and mental readiness to invest in effort were used
to relate to the performance data found. Sixteen individuals (7M and 8H)
participated in the study. No significant differences (p=0.2085) were
observed in the total number of repetitions between PLA (226.2+36.32) and CAP (221.8+39.84) conditions. Analyzed by rounds, there was a progressive and significant increase in PSE (p<0.0001) in both supplementation conditions,
however, the individual values of final PSE did not show significant
differences between the supplementation conditions (PLA 8,15+1,13; CAP
8,28+0,79; p=0,483). In general, the scale of readiness to invest in effort
showed no improvement with CAP compared to PLA (Mental p=0,38; Physical
p=0,52), but for men there was (Physical p=0,047; Mental p=0,028 ). Acute
capsaicin supplementation did not increase performance and did not reduce
perceived exertion in a Crossfit® exercise, only improving physical
readiness to invest in men`s effort.
