Theresult of study showed that there was significant difference (P<0.05) in the cortisol levels before exercise 13.49 ± 0.90ug/dl Compared with after exercise 15.10±1.08ug/dl. It was also observed that there was no significant difference in the cortisol level (P>0.05) obtained from the female subjects before and after exercise between the ages of 21-23, 24-26 and 27-29 years.
