ABSTRACT
This study aims to determine the effect of red ginger-infused water immersion time variations on increasing aerobic capacity as measured by VO2max in sports students. The research method used was an experiment with a pre-test-post-test control group design. In this study, a sample of 24 people was obtained, which was divided into 3 groups, each consisting of 8 sports students. A single blind technique was used, and the groups were divided into three treatment groups with different red ginger-infused water immersion times, namely 6 hours, 9 hours, and 12 hours. VO2max measurements were taken before and after the intervention using the beep test with a validity of 0.77. The results showed a significant increase in VO2max (p < 0.05) in all treatment groups after consumption of red ginger-infused water. The average increase in VO2max in the 6-hour group was 2.55 卤 0.84 ml/kg/min, in the 9-hour group it was 5.52 卤 1.44 ml/kg/min, and in the 12-hour group it was 6.56 卤 1.25 ml/kg/min. However, the One-way ANOVA test results showed no significant difference (p = 0.073 > 0.05) in the increase in VO2max between immersion time groups. It can be concluded that consuming red ginger-infused water with an immersion time of 6 hours, 9 hours, and 12 hours effectively increases the VO2max of sports students. However, the difference in effectiveness between immersion times is statistically insignificant. For this reason, infused water can be recommended as a natural ergogenic and increase aerobic capacity in sports students.
