Procedures
Forty-eight hours before testing, the subjects were not allowed to engage in RT or any other strenuous physical activity. The volunteers were also not allowed to drink alcohol or coffee before testing and had to appear in a fasted state. However, about 300-400ml of water had to be drunk in the morning to equalize the water balance. All measurements (T0–T2) were conducted single-blind in the morning (7.30–11.00 am) at the same time of the day by the same researcher.
