Design outcomes
Primary
| Measure | Time frame |
|---|---|
| An increase in the peak power output obtained during the sprints performed in the intermittent exercise protocol on the cycle ergometer is expected;There was a significant increase in maximum power in sprints number 2, 3, and 4 in the caffeine (CAF) condition compared to the placebo (PLA), with p<0.05 | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected that in the group supplemented with caffeine, there will be an increase in average power during sprints; a reduction in the Rate of Perceived Exertion (RPE), assessed by the Borg Scale;There was no significant difference between the studied groups (caffeine and placebo) regarding average power in sprints and Perceived Exertion (PE), assessed by the Borg Scale | — |
