All values are presented as mean (SD).
aA general linear model was used to determine differences in baseline measures adjusting for sex, age, BMI, alcohol intake, and physical activity.
bA linear mixed effect model for ROMs or BAP was used to determine the interaction between exercise and water intake while adjusting for sex, age, BMI, alcohol intake, and physical activity, with subject as a random effect.
Within-group comparisons between baseline and post-exercise measures were analyzed using a paired t-test. *p < 0.05, **p < 0.01, ***p < 0.001.
HIGH, high-water drinkers; LOW, low-water drinkers; ROMs, reactive oxygen metabolites; U.CARR, Carratelli Units; BAP, biological antioxidant potential.
