Figure 1: Moderate treadmill exercise increased serum corticosterone but decreased lactate levels. The blood lactate and serum corticosterone levels of rats submitted to 4 weeks (20 min/day, 5 days/week during four weeks) of treadmill exercise. The blood lactate level was measured with a lactate analyzer (a), and serum corticosterone was measured by ELISA (b). Values are mean ± standard error of control/sedentary (SED) ( ) and exercise (EXE) group ( ). *means significantly different from other group (Student’s -test, ).
