Abstract

This study aimed to investigate the relationship between physical characteristics and walking ability in the elderly population. Subjects were 77 elderly (38 men and 39 women) who are capable of walking independently with and without walking aids. Correlation and stepwise multiple linear regression analyses were used to analyze the relationship between physical characteristics (age, gender, height, weight, body mass index, muscle mass, waist/hip ratio, heart rate, vital capacity, flexibility, maximum oxygen consumption, one-leg standing time, and strength of knee flexor and extensor) and walking velocity of subjects. Age, height, vital capacity, one-leg standing time, and strength of knee flexor and extensor showed significant correlations with walking velocity of subjects (p<.05). Further, the strength of knee flexor explained 27% of the variance, and up to 32% of the walking velocity could be explained when the strength of knee extensor were added to the model. The findings suggest that walking velocity of elderly depends on the strength of lower limb's strength and a variety of physical characteristics.

본 연구는 노인들의 신체적 특성이 보행 속도에 어떠한 영향을 미치는지 알아보기 위하여 시행되었다. 연구대상자는 보조도구의 사용에 관계없이 독립보행이 가능한 노인 77명(남 38명, 여자 39명)을 대상으로 하였다. 상관분석과 단계적 다중 선형 회귀분석을 사용하여 신체적 특성(연령, 성별, 신장, 체중, 신체질량지수, 근육량, 허리/엉덩이둘레비, 심박수, 폐활량, 유연성, 최대산소섭취량, 눈감고 한발 서기)과 하지 근력(슬관절 신전근, 슬관절 굴곡근)이 보행 속도와 어떠한 관련성이 있는지 분석하였다. 보행 속도는 연령, 신장, 폐활량, 눈감고 한발 서기 시간, 슬관절 굴곡근 및 신전근의 근력과 상관관계가 있었다. 또한 슬관절 굴곡근에 의해 보행 속도는 27%로 설명력을 가지고 있었으며, 슬관절 신전근 변수가 추가되었을 때 설명력은 32%로 높아졌다. 이러한 결과는 노인의 보행 속도가 하지의 근력과 다양한 신체적 특성에 영향을 받는다는 것을 의미한다.
