Introduction and aim: The aim of present study was to assess the effect of six weeks Badminton training

on changes of stress and cortisol levels in non-athletic female students. Materials and Methods: In this

study estimated stress of 120 non-athlete students by stress questionnaire (HAD scale). Were measured

Among subjects who had suffered highest stress, 30 subjects with a mean age of 86/2 ± 22 years, height

56/5 ± 163 cm and weight 95/4 ± 57 kg were selected. Cortisol were measured by the bloodletting. The

subjects were divided into two experimental and control groups as homogeneous. But the control group did

not perform any activity. After training protocol variables were measured again in the same conditions. To

estimate the effect of independent variables on the dependent variable of the t-test and the independent ttest

to compare groups with a significance level (p <0/05) was used. Data were analyzed using spss and

Excel software.

Results: The results of this study showed that doing a six-week badminton practice reduces cortisol levels

(p =0.005), and decreasing stress (p =0.03) in the experimental group.

Conclusion: There was significant change in levels of cortisol and stress in experimental group.
