This study examined the association between cardiorespiratory fitness, adiposity, and mortality in older adults. It found that higher fitness levels were associated with lower mortality rates regardless of body composition. Specifically, even obese individuals had lower mortality if they were fit compared to unfit normal-weight or lean individuals. The study also found a J-shaped relationship between BMI and mortality both before and after adjusting for fitness levels.
