Observation On The Effect Of Low-load Running Combined With Blood Flow Restriction Training

Research purpose:To compare the effects of low-load running training combined with blood flow restriction training(BFRT)with running training alone in improving the cardiopulmonary function,knee flexion and extension strength,and improving body composition of exercisers difference.Research method:This study recruited 14 healthy young men from Beijing Sport University as test subjects.They were randomly divided into a control group and an experimental group for a four-week intervention.The subjects in the control group received a 40%VO2MAX load twice a week.Running training lasting 15 minutes.In the experimental group,under the same other conditions,the blood flow restriction band was used for training.Before and after training,the subjects’ VO2MAX,body composition,knee joint flexion and extension data were collected,and conclusions were drawn through data statistics and analysis.Research results:The maximum peak torque(Nm)of the knee joint flexors and extensors of the experimental group and the control group after 4 weeks of intervention,there was a significant difference between the before and after differences(P<0.05).In terms of the relative maximum oxygen uptake VO2MAX(ml/kg·min),the VO2MAX of the control group and the experimental group showed an upward trend after the intervention,and there was a significant difference between the before and after the difference(P<0.05);The body fat rate(%)of the group and the control group did not change significantly after the intervention,and there was no significant difference between the before and after differences(P>0.05).Research conclusion:For healthy adult men,low-load running training combined with BFR can improve the muscle strength and relative maximum oxygen uptake of the knee flexors and extensors more effectively than conventional running training.Therefore,this study recommends The combination of BFR and low-load running training is used as a more efficient running training method for mass sports.
