Hydration Status of Elite Youth Soccer Players: Training Versus FIFA Competition
Differences in body weight were observed in two of the training sessions, with greater variation in the competition (3.5% of BW, <i>p</i> < 0.001). Significant differences were found between weight losses in training sessions vs. matches. An increase in initial weight was associated with lower urine density. Regression coefficients showed that differences in body weight can predict urine density during training and competition (<i>p</i> < 0.05). A decrease in final body weight could be a valid indicator as a predictor of higher urinary density.
