Figure 6: Moderate treadmill exercise decreased NO levels in hippocampus of rats. GSH (reduced form of gluthatione) and NO content in the hippocampus of rats submitted to treadmill exercise (20 min/day, 5 days/week during four weeks) were analyzed. Twenty-four hours after the last session of exercise, hippocampi were dissected out and homogenized for measurement of GSH (a) or NO (b). Values are mean ± standard error of control/sedentary (SED) ( ) and exercise (EXE) ( ) group. *means significantly different from respective control/sedentary group (Student’s -test, ).
