Design outcomes
Primary
| Measure | Time frame |
|---|---|
| We will seek to assess anxiety, mood and cognition levels, using questionnaire application methods to assess anxiety, mood and cognition levels through scores (number) generated by each questionnaire applied. We expect that caffeine intake at different doses can reduce anxiety scores, perceived exertion and perceived muscle discomfort, increase mood scores and improve cognitive ability in individuals after a strength training session compared to questionnaire scores assessed before strength training | — |
Secondary
| Measure | Time frame |
|---|---|
| We expect to find an improvement in the scores of the affective parameters of tolerance, satisfaction and preference for exercise, with the intake of caffeine in the minimum and maximum doses after a single training session, through the method of applying questionnaires. These measurements will be evaluated at the end of each exercise series (monitoring during) and after exercise;We hope that with the minimum dose of caffeine or placebo we can observe a smaller change in blood pressure and heart rate after a strength training session when compared to the assessment before exercise with smaller doses of caffeine or placebo through the use of a pneumatic cuff with a digital screen to evaluate hemodynamic parameters and a chest strap with an attached heart monitor (AVANUTRI®) to evaluate heart rate variability. Real-time heart rate data will be monitored via the HRV Elite app, cell phone or computer. Heart rate measurements will be taken with participants lying down for 10 minutes, before and after exercise | — |
