Abstract
BackgroundThe strategy of successful ageing is an important means to deal with the challenges of the current ageing society. This paper aims to explore the effects of different intensities of physical activity on the successful ageing of the elderly.MethodsOur data were from wave 4 of the China Health and Retirement Longitudinal Survey (CHARLS), involving 9026 residents aged 60 years and older. The intensity of physical activity was divided into three levels: vigorous, moderate and mild. The concept of successful ageing adopted a four-dimensional model of life satisfaction added to the theoretical model of Rowe and Kahn’s. Propensity score matching (PSM) with controlling nine confounding factors were used to analyse the effects of different intensities of physical activity.ResultsThe percentage of successful ageing was 1.88% among all subjects. Among them, 30.26, 29.57 and 29.40% of the elderly often participated in vigorous, moderate and mild physical activity, respectively. The results of PSM showed that participation in moderate activity increased the probability of successful ageing of the elderly by 0.76–0.78% (P < 0.001), while participation in vigorous and mild physical activity had no significant effect on successful ageing (P > 0.05). Moderate physical activity had statistically significant effects on four components of successful aging, including major disease, physical function, life satisfaction, and social participation (P < 0.05).ConclusionModerate-intensity physical activity was most beneficial to the successful ageing of the elderly and should be promoted in the elderly population.

Ageing has become a major global challenge
Data and sampling The data used in this study were collected from wave 4 of the China Health and Retirement Longitudinal Survey (CHARLS), which is available at http://charls.pku.edu.cn
Exercise and successful ageing status of the elderly First, a descriptive analysis was carried out on the physical activity and successful ageing of the elderly, and a one-way ANOVA was used to compare the differences in successful aging among the three groups performing high-intensity, moderate-intensity, and mild-intensity exercise
Summary
Ageing has become a major global challenge. By 2050, the population aged 60 and above will reach one-fifth of the total population [1]. To actively deal with the problem of population ageing and steadily improve a healthy life expectancy, the World Health Organization (WHO) strongly advocates the concept of healthy ageing and proposed the strategy of healthy ageing in 2015 with the aim of overcoming or minimizing the adverse consequences of population ageing through human intervention. As early as the 1980s, American scholars Rowe and Kahn [2] proposed the classic definition of successful ageing, that is, successful ageing should simultaneously meet the three-dimensional theoretical model of avoiding disease and the functional loss, maintaining physical and cognitive functions, and actively participating in social activities. The strategy of successful ageing is an important means to deal with the challenges of the current ageing society. This paper aims to explore the effects of different intensities of physical activity on the successful ageing of the elderly
