Abstract
Introduction: Exercise with Blood Flow Restriction (BFR) is a new method of exercise that coaches used it. This study aim was investigating the effect of 4 weeks' interval cycling exercise with blood flow restriction on beginner cyclists’ hematologic factors and 4000 m cycling performance.
Methodology: Twenty students of Shiraz Education Cycling Team with an age average of 16.43 ± 1.36 years, weight of 60.07 ± 11.74 kg, height of 175.46 ± 6.14 cm and BMI 19.43 ± 3.11 participated voluntarily in this experimental study. The participants were divided randomly into two equal groups of interval cycling along with BFR (n=10) and interval cycling without BFR (n=10). Both groups trained 3 sessions per week in 4 weeks' interval cycling exercise. and interval cycling exercise consisted of 10 repetitions for one minute and one-minute rest between repetitions. BFR was applied by cuff with a width of 15 cm and pressure of 160 mmHg.
Results: After 4 weeks training no significant changes observed on hematologic factors P<0.05 in BFR group but MCH P=0.007 and MCHC P=0.001, decreased in control group. 4000 m time trial cycling performance improved in BFR group P=0.001 and control group P=0.005. No significant difference was observed between the effects of the two exercise methods on hematologic factors and 4000 m cycling performance (P<0.05)
Discussion: also no significant difference was observed between the effects of the two exercise methods on research variables, but cycling with BFR had more effective %14.32 than without BFR %9.22 on 4000 m time trial cycling performance. So interval cycling training with BFR suggested as a new method for improving cycling performance.
