The ground reaction force during walk on different condition was measured including level walk and stairway condition. The subjects were healthy students. The foot pressure was measured by using a foot scanning system (Nitta Co. Ltd). The distribution of the foot pressure and the peak value of it during contact with the ground during walk continuously by using the foot scanning systemThe foot pressure was compared with each result of the three different conditions. The value of foot pressure during walk was reported as less than 150% of body weight which will not be able to cover the enough strength or value for keep a the human bone as a healthy condition.In case of the level walking, the speed was needed more than 6Km/h for getting the 150 % of body weight pressure during free walk. Even a case of 4Km/h of free walking, 150% of value was produced carrying with the weight of more than 10% of body weight.Incase of stairway condition, the enough pressure was obtained for cover the more than 150% of stress. More than 200% of stress was obtained in case of carrying 10% of weight of the body weight. It will be recommended that, the stairway condition should be considered for a better walking of getting an enough bone stress.

测量了不同行走条件下的地面反作用力，包括水平行走和楼梯行走。研究对象为健康学生。使用足部扫描系统（Nitta Co. Ltd）测量足部压力。利用足部扫描系统对连续行走过程中足部压力的分布及足部压力与地面接触时的峰值进行比较，并与三种不同情况下的各结果进行比较。据报道，步行时足部压力的值小于体重的150%，这将无法覆盖足够的强度或值来保持人体骨骼的健康状态。在水平行走的情况下，在自由行走时，速度需要超过6Km/h才能获得150%的体重压力。即使在4公里/小时的自由行走情况下，携带超过体重10%的重量也产生了150%的价值。在楼梯工况下，获得的压力足以覆盖150%以上的应力。当承载重量的10%时，可获得200%以上的应力。建议在楼梯条件下进行更好的步行，以获得足够的骨应力。
