Reduced Body Flexibility Is Associated With Poor Survival in Middle-Aged Men and Women: A Prospective Cohort Study.

Objectives: Flexibility is recognized as one of the components of physical fitness and commonly included as part of exercise prescriptions for all ages. However, limited data exist regarding the relationship between flexibility and survival. We evaluated the sex-specific nature and magnitude of the associations between body flexibility and natural and non-COVID-19 mortality in a middle-aged cohort of men and women.
