Establishing sex- and age-specific normative values for the Senior Fitness Test among community-dwelling elderly aged 70 and older in Eastern China: a community-based study

Abstract

Background The preservation of physical health is of crucial importance for the overall well-being of the ageing population, a concern that is particularly relevant in the context of rapidly ageing societies such as China. The Senior Fitness Test has emerged as an instrument for evaluating and monitoring the physical fitness of elderly individuals. However, there is a lack of data regarding the normative values of physical fitness among community-dwelling elderly people aged 70 years and older in China. Objective This study aims to propose sex- and age-specific normative values for the components of the Senior Fitness Test in a large-based sample of Chinese aged over 70, thus contributing to the development of more tailored interventions addressing the aging trends. Methods A total of 21,305 community-dwelling elderly individuals aged over 70 (53.02% female) were evaluated using the Senior Fitness Test in Hangzhou, China. Sex- and age-specific normative values for each component were computed, ranging from the 5th to the 95th percentile, with increments of the 5th percentile. Results The results showed that the normative values vary by gender and age, declining with age in both males and females. Males exhibit superior strength, endurance, and dynamic balance, while females tend to have greater flexibility. Conclusion This study established sex- and age-specific normative values for selected components of the Senior Fitness Test among elderly individuals in China. The study’s findings provided performance standards for clinically assessing the physical fitness of Chinese seniors and could serve as valuable insights for future research endeavors.
