Background: Physical exercise is essential for performance of the immune system. The integrity of immune response is dependent on the intensity and duration of the exercise performed. During exercise the metabolic and hormonal changes that occurred can induce lymphocyte apoptosis. Dehydroepiandrosteron sulphate (DHEAS) is one of the hormones that is affected by exercise, it is an androgen released from the adrenal cortex in response to adrenocortiocotropin releasing hormone (ACTH). DHEAS is regarded as an anti-aging hormone; it is primarily immune enhancing, providing some degree of counterbalance to the potentially detrimental effects of catecholamine and cortisol which are immunosuppressive if chronic
