This study examined the association of gait variability and physical fitness with frailty status in older women. In a cross-sectional design, 168 elderly women, aged 65 years and older (75.07±5.40 years), measured body composition, gait parameters gait variability, physical fitness variables, MMSE-DS and CES-D. Subjects were classified as robust, pre-frail, and frailty based on the Fried et al.(2001) criteria for frailty weight loss, exhaustion, low hand-grip strength, low gait speed, and physical inactivity. Logistic regression analyses were used to determine the odds ratio (ORs) and 95% confidence interval (CI) of frailty status for having gait variability and physical fitness levels. Compared to the robust group (OR=1), the frailty group had significantly higher ORs of having terminal double limb stance (OR=1.48, 95% CI=0.10-2.21, p=.049), step cadence (OR=2.06, 95%CI=1.20-3.43, p=.009) variability, and significantly lower ORs of having upper-strength (OR=0.49, 95%CI=0.31-0.77, p=.002) even after adjusting for age, education, comorbidity, K-IADL, MMSE-KC and CES-D score. The finding of this study suggested that terminal double limb stance, step cadence and upper body muscular strength were independent predictors of frailty.

노화가 시작되면 체력이 저하되어 면역기능이 떨어져 쉽게 병에 걸리고 환경에 대한 적응력이 떨어진다. 특히 60세 이상이 되면 근육 양과 근력이 급격히 가속화되어 신체적으로 약화되기 시작한다. 노화는 자연스럽게 진행되지만 꾸준한 운동을 통해 근력 저하 속도를 늦출 수 있다. 근력 증강을 위한 다양한 기기 개발에도 불구하고 노인들이 사용하는데 어려움이 있다. 특히 노인 신체적 특성에 맞는 운동기기 개발이 절실하며, 노인의 흥미를 유발시켜 자발적 참여를 유도하는 환경이 제공되어야 한다. 가상현실 기술은 실재하지 않거나 먼 거리에 있는 환경을 가상세계로 생성시켜서, 인간의 오감을 각종 인터페이스 장치를 통해 신호를 전달하여 가상의 현실 환경에 실재하고 있다고 느끼도록 만들어 주고, 가상세계와 상호작용을 통해 의료 진단, 치료, 재활 등에 유용한 도구 및 환경을 제공한다. 이러한 가상현실 기술의 특성 때문에 노인의 운동 참여와 운동 효과를 극대화 할 수 있다. 본 논문에서는 근력의 특성을 분석하고 노화와 근력과의 관계를 조사하고, 상지근력 증강 운동기와 해당 가상현실 컨텐츠 그리고 관련 컨텐츠 개발 동향에 대해 제시하고자 한다.
