Abstract

Background and Aim: Occlusion training is a new training method that has a favorable effect on blood cells and also simulates the effect of training under hypoxia. The present study was aimed to investigate the effects of short-term sub-maximal cycling along with Blood flow restriction on serum level of red blood cell (RBC), Hemoglobin (HGB) and Hematocrit (Hct ) in active males. Materials and Methods: In this way, 24 physical education and sport sciences students from Kharazmi university were selected. They were assigned into three groups based on maximum power cycling including Blood flow restriction group (n=8), cycling with unrestricted group (n=8) and control group (n=8). The Occlusion training and non-occlusion training groups have been trained for 3 weeks, 3 sessions per week. Each session included 3 stages of cycling with maximum power of 50 percent with a rest interval of 30-45 seconds for every session which lasted 3 minutes. The amount of pressure on the thigh of participants in the restriction group was 140-170 mmHg and the dependent variables were measured by using the cellular cell device containing anticoagulant. For statistical analyzing dependent samples t-test, one-way analysis of variance, and Tukey tests were used at the significant level of p≤ 0. 05. Results: The results showed that 3 weeks of sub-maximal cycling with Blood flow restriction induced significant changes in RBC, HGB and Hct (p≤ 0. 05) as compared to pre-test. But these changes were not significant in the non-occlusion training and control groups. On the other hand, the inter-group analyses showed that after 3 weeks of submaximal cycling, there are significantly differences between restriction and no-restriction group regarding HGB (p=0. 02), RBC (p=0. 02) and Hct (p=0. 03) indices Conclusion: The results revealed that the local blood restriction during sub-maximal cycling have a positive effect on the blood levels of HGB, RBC, and Hct. Therefore Oclussion training can simulates some degree of exercise effect in hypoxia conditions.
