EFFECTS OF SPRINT INTERVAL AND CONTINUOUS ENDURANCE TRAINING ON INFLAMMATORY

Chronic and inflammatory diseases are more factor of death; while there is reverse relationbetween cardiopulmonary fitness and disease. In the other hand; anti-inflammatory effects ofexercise training have been confirmed and it's effect have been showed on pro and antiinflammatory cytokines. The aim of this study was to compare the effects of two type of sprintinterval (SIT) and continuous endurance (CET) training on inflammatory factors. Researchmethod: Sixteen students who had recreational activities participated in the study and wererandomlyAssigned to two training groups (age 23.62±2.33 year; weight 65.26±9.38 kg Vo2max33.96±5.62 ml/kg/min). The SIT group completed a training protocol 3 days/wk for 2 weekswhich included four to six 30-s “all-out” Wingate tests separated by 4 min of recovery. The CETprotocol included 90-120 min cycling at 65% of their maximum oxygen uptake (Vo2max) whichwas performed 3 days/wk and for two weeks. In each group two blood samples were collectedbefore and 2 days after the training. Blood and serum samples were analyzed for IL-6; IL-10 andCRP; white blood cells (WBC); glucose and insulin. HOMA-IR was calculated by using theglucose and insulin concentrations. Data were statistically analyzed by using repeated measuresof ANOVA and Mann-Whitney U. Results: Results shown that there was no significantdifference between the two training effects on all measured parameters (p>0.05). However; CRP;IL-10 and WBC levels were decreased in response to both training protocols; though IL-6 and IRdecreased in SIT while in response to ECT protocol IL-6 increased and IR was not significantlychanged. Discussion and Conclusion: Based on the findings of the present study it wasconcluded that the sprint interval training and continuous endurance training would affect oninflammatory markers similarly.
