Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome 1: The primary expected outcome of the study is peak anaerobic power during the first 4 jumps, assessed through the repeated jump test. This parameter was used to calculate the sample size and is considered the most relevant for determining the effects of guaraná supplementation (5 mg/kg of caffeine) | — |
Secondary
| Measure | Time frame |
|---|---|
| Outcome found: As secondary outcomes, additional improvements in anaerobic fitness parameters were observed, including maximum jump height and average jump height, which showed significant increases compared to the placebo group, as well as peak power during the first 4 jumps, further supporting the positive effects of guaraná supplementation (5 mg/kg of caffeine) on anaerobic performance. | — |
