Introduction & Objective: Both exercise and unnatural environments causes alter in immune system function. The aim of this study was to compare the effect of exercise on the total numbers of blood Leukocytes, and platelets of the athletes in temperature conditions cold, warm and normal.
Materials & Methods: This clinical trial study was conducted at Tehran University in 2011. Ten young male endurance athletes, conducted the same exercise(treadmill running) for an hour at the intensity of %60VO2max in three temperature conditions of normal (22±1˚c, 50±5RH), cold (3±1˚c, 50±2) and warm (35±1˚c, 50±5). Blood samples were collected before, immediately after exercise and two hours later(during recovery)
Inclusion criteria included; having a history of at least 3 years of continuous and 8 hours per week of exercise endurance; maximal oxygen consumption 50 ml kg min; the absence of any disease of the immune system; vascular Kvrnr and infection in the past month; such as influenza; to colds; respiratory infections Hungarian; or symptoms such as fever; sore throat; runny nose; cough and other infectious diseases.
The use of doping substances such as vitamins; dietary supplements; herbs or medications that affect the immune system are effective; Smoking and alcohol 48 hours before the test; Participate in heavy exercise; exposure to adverse environmental conditions; temperature; disease and viral infection during the plan period; were exclusion criteria.
