Abstract: Objective: To observe the effects of core strength training on the body balance of middle-aged men, which could provide evidence for improving the body balance and reducing the risk of falls in the middle-aged men.Methods: Sixteen 50~60 years old men were randomly divided into experimental group (core strength training, n=8) and control group(n=8). Intermittent core strength trainings were used for dynamic and static training, push-pull training and unarmed lower limb strength training by suspension ropes and yoga mat. The time for training was 50~60 min/day, 4~5 times/week for a total of 10 weeks. The men in control group remained their original living habits. We measured the ability of body static balance and dynamic balance before and after the core strength training.Results: ① Compared with before exercise training, both closed single foot standing time and the body dynamic balance were increased significantly in the experimental group after exercise training(P<0.01)(10.63±1.69 s vs 9.00±2.27 s; 77.38±10.94 vs 89.50±5.53). ② Compared with before exercise training, star excursion balance test(SEBT) values were significantly increased in the left leg(the right leg support) in eight directions and the right leg(the left leg support)in six directions (P<0.01).Conclusion: Ten-week core strength training can significantly increase the body static and dynamic balance in the middle-aged men.
