Glycogen phosphorylase a and phosphofructokinase activity in rats during STHA (6, 12, 24 and 48 h) and LTHA (7, 14, 21 and 28 days) heat acclimation at 35 ± 1°C. *p < 0.05 in comparison with control (C) animals. Coefficient of correlation (r) between GPa/PFK during whole experimental period (r G6P/HK = 0.807), STHA (r G6P/HK = 0.988) and LTHA (r G6P/HK = 0.706)
