Design outcomes
Primary
| Measure | Time frame |
|---|---|
| An increase in oxygen consumption during treadmill exercise is expected after supplementation with betalain, caffeine, arginine, or ginger, compared to the placebo condition. This was verified through spirometric analysis using the Cortex Metalyser 3B gas analyzer. A statistically significant difference (p < 0.05) in mean VO2 between the supplementation and placebo conditions will be considered. | — |
Secondary
| Measure | Time frame |
|---|---|
| A reduction in maximum heart rate during submaximal exercise is expected after supplementation. This will be verified using a heart rate monitor. A statistically significant difference (p < 0.05) in mean maximum heart rate between the supplementation and placebo conditions will be considered.;A reduction in perceived exertion during exercise is expected, as assessed using the Borg scale. A statistically significant difference (p < 0.05) in the mean Borg scale score between the supplementation and placebo conditions will be considered. | — |
