Studies correlating physical activity and successful aging

Study	Type of study	Number of subjects examined	Results
MacArthur study; Berkman et al. [11]	Observational population study	4030	High functioning older people were much more likely to engage in strenuous physical exercise, compared to medium and low functioning groups
Australian Longitudinal Study of Aging (ALSA); Andrews et al. [12]	Observational population study	1403	Lower levels of functioning were associated with lower levels of activity and physical performance
Prognostic Indicator of Cardiovascular and Cerebrovascular Events (PROOF) study; Achour et al. [18]	Observational population study	686	Higher physical activity levels were associated with higher satisfaction with individual health and well-being
POLSENIOR study; Rafał Rowiński [26]	Observational population study	213	Six months of physical activity classes for older people improved their physical function and self-reported quality of life
Almeida et al. [16]	Observational population study	12,201	Participating in at least 150 min of vigorous physical activity per week was associated with improved survival and healthy aging in older men
Part of The 10/66 Dementia Research Group; Daskalopoulou et al. [13]	Observational population study	5000	Older people engaging in physical activity had increased odds of healthy aging
The Blue Mountains Eye Study (BMES); Gopinath et al. [19]	Observational population study	1584	Older adults who engaged in high levels of total physical activity had higher chances of aging successfully 10 years later
English Longitudinal Study of Aging (ELSA); Rogers et al. [21]	Observational population study	8649	Mild physical activity was not associated with better trajectories of frailty progression. Moderate and high levels of physical activity were beneficial on frailty trajectories
WHO SAGE Wave 1 (China); Feng et al. [20]	Observational population study	13,367	150 min/week of vigorous to moderate physical activity was associated with better physical function, better cognitive function, higher quality of life and fewer depressive symptoms
PoliFIT pilot trial; Bernardelli et al. [22]	Observational population study	186	Four months of physical activity classes did not have an effect on the function of older people measured by the time needed to walk 400 m
Tromsø Study; Opdal et al. [14]	Observational population study	12,241	Lack of physical activity was associated with an increased risk of mortality and worse self-reported health compared to physically active subjects
Ageing Trajectories of Health: Longitudinal Opportunities and Synergies (ATHLOS) project; Moreno-Agostino et al. [15]	Observational population study	130,521	Physical activity has a positive impact on the trajectory of aging, supporting healthy aging
Lin et al. [17]	Observational population study (meta-analysis of cohort studies)	189,192	Physical activity was associated with higher chances of successful aging in middle-aged and older people
