The impact shock occurred at heel during running is transmitted to head through body. It acts one of body loads and is important factor which cause injuries on joint, tendon and ligament by recurring stance. This study is conducted characteristics of body that impact shock is transmitted by measuring and comparing acceleration of shank and head with 5 running speeds and whether wearing footwear or not. The magnitude of acceleration on shank during wearing footwear is less than non-wearing, but it on head is not significant between wearing and non-wearing in rapid speed. Also, the magnitude of acceleration on each segments is shown rapidly increasing with running speed increased. When wearing and non-wearing, the values of shank on 6.Om/s are respectively 3.4, 2.7 times than their of 3.Om/s, on head are 5.5, 3.3 times.
