Effect of a period high intensity interval training in two condition hypoxia and normoxia on leukocyte and CBC in response incremental exercise

The propose of present study examined the effects of intense interval training in hypoxic conditions (14%PO2) and normoxic conditions (21%PO2) on blood cells and leukocytes in response exhaustive test. 16 man active (ages 23/27±2/94 years، height 178/13±5/86 cm، weight 78/8 ± 06/74 kg، fat body، 19/33±3/07) were randomly divided into two groups: active hypoxic conditions (14%PO2) and normoxia (21%PO2) groups. Before beginning training، exhaustive testing to determine maximal workload (Wmax) were performed، blood samples were taken before and immediately after the test. After completing the training، exhaustive testing similar to the first day Performed. Exercise protocol consisted of 40 minutes of exercise، six days per week، was performed in two following weeks. Each session includes a five minute warm-up، 10 Step- three minutes pedal (one minute intensity of 50% Wmax and two minutes intensity of 85% -80% Wmax) and had a five minute cool down. The first group training in hypoxic conditions (14% pO2) and the second group training in normoxic (21% pO2) Performed. In this study، repeated measure was used to analyze the hypothesis. Training inHypoxia led to a significant increase in the amount of RBC، hemoglobin and a significant reduction in the accumulation eosinophil- platelets in response to exhaustive testing than normoxic conditions in response to exhaustive testing. As a result of training، significant changes in the levels of neutrophils، monocytes، lymphocytes in response to exhaustive testing was not observed in both groups. It can be concluded that the intense interval training in addition to hypoxic conditions can increase red blood cells in response to exhaustive test and can reduce the risk trombosis be exhaustive.
