Effects of eight weeks of regular exercise in the morning serum factors of immune systems and cortisol levels in women

The purpose of this study was to determine changes in serum immunoglobulin A concentrations & cortisol levels in women's after eight weeks exercise in the morning.
Material and This study was experimental study and 32, healthy, adult inactive women's (aged 30-40 years, main weight 60.5± 3.5 kg and main height 165± 4.5 cm) were randomly selected and assigned to either the control and the exercise group their exercise program consisted of three sessions a week, for eight weeks. Each subject performed exercise at 06:00 a.m during the study, while controls continued their normal life style. Changes in fasting IgA concentrations and cortisol serum levels were monitored at the beginning and end of exercise at every session. Data Analysis was performed based on descriptive and analytical methods.
There were not any significant differences between the mean levels of serum IgA in the exercise group than control group (P>0.05), while, the levels of serum cortisol (17.7±6.2 μg/dl ) significantly greater in the exercise group than control group (P The results of this study showed that participation in training the control and the exercise group has no effect on serum levels of IgA, but change levels of serum cortisol that may be due to hormonal response and physiological stress.
