Changes in plasma f-Trp (A), serum IGF-1 (B), and BDNF (C) levels from rest to 60MPE by fluid intake of water or a sports drink during treadmill running in a thermoneutral environment and in an environment with a high ambient temperature.

Values are mean ± standard error. * Significantly different from Rest in group 18 (p < 0.05); ^# Significantly different from Rest in all groups (p < 0.05); ⁺ Significantly different from IAE in group 18 (p < 0.05); and^a Significantly higher in group 18 compared to group 32 (p < 0.05).
