The use of footscan balance test system of national high-level pistol, rifle shooters had a balance of stability tests, by analyzing the following major conclusions: First, all the athletes in men's pistol shooting athletes body posture and adjusting the balance of stability the capacity of the worst; the second, firing only state body sway eyes open area and before and after the shaking smaller decrease; and thirdly, the general balance of the stability of indicators (both before and after the body center of gravity, around shaking rate, trajectory length, shaking the area) can not accurately reflect the high level of shooting athletes balance the characteristics of stability, and derived indicators - per unit area of the track length (the total length of track and shaking the area ratio), both show the balance of stability, but also reflect the attitude adjustment ability, in the sway area certain circumstances, the greater its value, indicating that ability to regulate the more intense the frequency of shaking sooner, the better the stability of physical balance, in the actual shooting of firearms at the time of the impact of the smaller, can be used as shooting athletes evaluation and selection of indicators.

运用footscan balance测试系统对国家高水平手枪、步枪射击运动员进行了平衡稳定性的测试，通过分析得出以下主要结论：第一，所有射击运动员中男子手枪运动员身体姿态的平衡稳定性及调节能力最差；第二，射击训练只能使睁眼状态下身体晃动面积和前后晃动幅度减小；第三，一般平衡稳定性指标(身体重心前后、左右晃动幅度、轨迹长度、晃动面积)不能准确地反映高水平射击运动员平衡稳定性的特点，而派生指标——单位面积的轨迹长度(轨迹总长度与晃动面积的比值)，既显示平衡稳定性，又能体现姿态调节能力，在晃动面积一定的情况下，其值越大，表明调节能力越强，晃动的频率越快，身体平衡稳定性越好，在实射时对枪支的影响越小，可作为射击运动员的评价和选材指标。
