Analysis
The amount of fluid intake was measured by weighing each bottle to the nearest 0.1 g before and after individual sessions using an electric balance (BJ1500, Sartorius, Germany). The data were expressed as the mean ± standard error. In this article,all statistical decisions concerning the analysis of variance (ANOVAs) and any post hoc comparisons were based on an alpha level of .05. For simplicity, F values from ANOVA are reported only when they are statistically significant.
