Urinary (a) and (b) concentrations, systolic (c) and diastolic (d) blood pressures, blood glucose (e), lactate (f), serum cortisol (g), and (h) urinary urea taken at the baseline (T0), 60 min after gel ingestion (T60), before exercise (BE), after exercise (AE), and 20 min after the end of the exercise (+20). The symbol indicates significant difference compared to the PLA treatment. The symbol indicates significant difference compared to the PLA treatment. Different letters denote statistical significance within the same treatment in different time intervals at . Values are presented as mean ± SD for urinary , , blood glucose, lactate, cortisol, urea, and mean ± SEM for hemodynamic parameters.
