Abstract: Purpose Fitness Qigong competition requires athletes to control the body posture and to stabilize the body center of gravity, which poses very high demand on the core area muscle group. The core strength training helps to develop muscle strength in the core area, which has been confirmed in some competitive sports events. Coaches and athletes are thinking about introducing the training into the Qigong exercises. This research is an attempt to explore the role of the core strength training in the fitness Qigong competition. Method 6 male Qigong athletes are picked out as the experimental targets to heir core strength training for three months. 4 tests are conducted during the period, and the testing items include the core isometric strength, the equilibrium ability in the core area, the body balancing ability, and the body flexibility. The test data are statistically processed and compared in order to learn the change patterns. Conclusion(1)The intervention can effectively train the flexion strength in the core area, and the promotion margin can reach from 10% to 30%。Moderate introduction of the core area strength training into the fitness Qigong competition helps to promote the specific fitness quality for the athletes (2) The core strength training program design should coincide with the difficulty characteristics of the Qigong action in order to improve the stability ability in the core area and to improve the flexibility quality in the same pace. Both strength and flexibility should be taken into consideration in the core strength training. (3) The intervention significantly improves the balancing ability in the weak leg of the testers over 50%, showing that the core strength training can effectively overcome the unevenness in the balancing ability.
