Abstract：BACKGROUND:High-intensity resistance training effectively improves muscle strength,but with a high risk of arteriosclerosis;high-intensity resistance training combined with aerobic exercise effectively reduces the level of arteriosclerosis;low-intensity resistance combined with blood flow restriction training does not require high load strength to stimulate muscles,which may be a scientific training method to improve muscle strength and maintain arterial elasticity. OBJECTIVE:To explore the effects of 12 weeks of low-intensity resistance training combined with blood flow restriction training on body composition,muscle strength,and arterial elasticity in young people,thereby providing theoretical support for the development of personalized training programs. METHODS:Fifty-five college students were randomly recruited and divided by drawing lots into high-intensity resistance training group,high-intensity resistance training combined with aerobic exercise group,and low-intensity resistance training combined with blood flow restriction training group. All participants were subjected to 12 weeks of high-intensity resistance training,high-intensity resistance training combined with aerobic exercise,or low-intensity resistance training combined with blood flow restriction training,and their body composition,muscle strength,and arterial elasticity were tested after training. RESULTS AND CONCLUSION:After 12 weeks of training intervention,the lean body mass of the high-intensity resistance training group and the low-intensity resistance training combined with blood flow restriction training group significantly increased (P<0.05). The one-repetition maximum and knee isokinetic muscle strength significantly increased in all the three groups (P<0.05). The arterial elasticity of the high-intensity resistance training combined with aerobic exercise group and the low-intensity resistance training combined with blood flow restriction training group significantly improved (P<0.05). These findings indicate that 12 weeks of high-intensity resistance training and low-intensity resistance training combined with blood flow restriction training significantly improve body composition;all the three training programs can increase muscle strength;12 weeks of high-intensity resistance training combined with aerobic exercise and low-intensity resistance training combined with blood flow restriction training both improve arterial elasticity,and the effect of low-intensity resistance training combined with blood flow restriction training is superior to that of high-intensity resistance training combined with aerobic exercise. Therefore,it is recommended that low-intensity resistance training combined with blood flow restriction training be used as the preferred training method to improve arterial elasticity,thus reducing the risk of arteriosclerosis.
