Grip strength is a well-known indicator of muscle strength. The trajectories of grip strength with increasing age refer to the aging and development process of muscle strength over one’s life span. The levels of muscle strength needed to perform activities of daily living or to prevent older people from developing disabilities are serious geriatric issues. Grip strength has been shown to decline with aging and to be a predictor of the development of geriatric problems, which suggests the lifelong management of grip strength has great potential for the promotion of healthy aging. The focus of this short review was to examine grip strength as an indicator of geriatric issues and to clarify the role of grip strength in relation to healthy aging.

To prevent a decline in gait with age, it is necessary to investigate age-related changes in gait performance and detect related factors. The purpose of this study was to assess the association between gait ability and leg extension power among middle-aged and elderly people. Height, weight, maximum gait velocity (MGV) and leg extension power (LEP) were measured in 752 males and females who participated in the National Institute for Longevity Sciences, Longitudinal Study of Aging (NILS-LSA). Age-related changes in MGV and LEP and the association between MGV and LEP were assessed. There were significant decline trends in height, weight, MGV and LEP with advancing age (p<0.001). MGV showed a significantly positive correlation with LEP (in males: r=0.48 p<0.001, in females: r=0.47; p<0.001). Subjects aged 60yrs and over showed a significantly higher correlation than those under 60yrs in males, but not in females, after adjustment for height and weight. Although the relationships between MGV and LEP were different by age and gender, LEP may be one of the important factors in maintaining gait ability. J Epidemiol, 2000 ; 10 : S77-S81.
