Associations between Starting to Exercise in Later Life and Survival among Older Adults: a Nationwide, Community-based, Prospective Cohort Study in China

Starting to exercise in later life can provide survival benefits for older adults, but only if they maintain exercise for over 20 years. This long latency period may suggest suboptimal exercise efficiency among older adults in real-world contexts; therefore, it is essential not only to emphasize the importance of long-term exercise but also to promote structured exercise within this population.
