Sponsor's own description
The objective of this study was to evaluate the variability of the heart rate of exercise physicists with and without caffeine intake. Practitioners of resisted physical exercise, specifically bodybuilding, who are young adults between the ages of 18 and 30 will participate in the study. To define the sample size, a sample calculation was performed based considering as variable the RMSSD index (square root of the square mean of the differences between the adjacent normal iRRs). The significant difference magnitude assumed was 12 ms, considering a standard deviation of 16.2 ms, with alpha risk of 5% and beta of 80%. A minimum of 14 subjects per group were required in the survey. A total of 32 subjects will participate in the research, being these divided and allocated in different groups. Sampling will be of the intentional kind.
