Aim. The purpose of this study was to examine the influence of carrying various loads on gait properties. Methods. Fifteen young male adults (age: 22.1±1.3 yr) conducted gait movement with six relative loads (0, 10, 20, 30, 40 and 50% of body mass: BM) based on each subject’s body mass, which attached on clothes equally.
Results. Stance and double support times extended and single support time and step length shortened in proportion to increasing loads. Namely, subjects became difficult to support their body with one leg long during walking, and gait became unstable and slowdown with increasing loads imposed on lower limbs.
Conclusion. It is highly possible that similar gait changes may be observed by a muscle function decrease of lower limbs with aging in a senile stage.
