本研究的目的是澄清负载和步态变化之间的关系，步态参数之间的步行时，不同的负载。15名健康青年男性（平均年龄：22.1 ± 1.6岁），分别以0、20、40和60%体重（BM）为负荷，以步行速度、步频、站立时间、摆动时间、双支撑时间、步长、步宽、行走角度和足趾角度为步态参数。步行速度、步频、站立时间和双支撑时间随负荷变化显著。步行速度与0%BM摆动时间（r = -0.64）和60%BM步行角度（r = -0.52）呈显著相关。0、20、40%BM时摆动时间与双支撑时间呈显著正相关（r=0.53-0.63），40、60%BM时步行速度与步长呈显著正相关（r =-0.61、-0.67）。摆动时间、双支撑时间与步行速度之间的关系，以及步行角度、步长与步行速度之间的关系随负荷变化很大。这些变化可能是为了保持稳定的姿势。J Physiol Anthropol 29（1）：29-34，2010 http://www.jstage.jst.go.jp/browse/jpa2 [DOI：10.2114/jpa2.29.29]
This study aimed to clarify the relationships between loads and gait changes and among gait parameters while walking with various loads. Fifteen healthy young male adults (mean age: 22.1 +/- 1.6 years) walked with four kinds of loads based on each subject's body mass (0, 20, 40, and 60% of body mass: BM) on his back.Walking speed, cadence, stance time, swing time, double support time, step length, step width, walking angle, and toe angle were selected as gait parameters. Walking speed, cadence, stance time, and double support time changed significantly with loads. The walking speed showed significant correlations with the swing time at 0% BM (r = -0.64) and the walking angle at 60% BM (r = -0.52). Significant correlations were found between swing time and double support time at 0, 20, and 40% BM (r=0.53-0.63) and between walking speed and step length at 40 and 60% BM (r = -0.61, -0.67).In conclusion, walking with loads produces large gait changes. The relationship between swing time, double support time, and walking speed, as well as between walking angle, step length, and walking speed changes greatly with loads. These changes may occur in order to maintain a stable posture. J Physiol Anthropol 29(1): 29-34, 2010 http://www.jstage.jst.go.jp/browse/jpa2 [DOI: 10.2114/jpa2.29.29]
