Exercise Is a Better Predictor of Longevity Than Your AgeA study published in the European Journal of Preventive Cardiology10 sought to estimate a patient’s age based on performance during an exercise stress test. Over 125,000 patients referred for exercise stress testing were included. Estimated age was based on exercise capacity. After nearly nine years of follow-up, researchers discovered the patient’s estimated age based on their exercise stress test was a better predictor of mortality as compared to chronological age. The results held true for both men and women. Researchers believe the key take-home messages were that exercise variables are powerful predictors of survival, and health care providers could consider using their physiological age as a way to motivate their patients to exercise more.11 A similar study12 evaluated 8,000 middle-aged and older adults and found adding the physical activity of any intensity or duration cut their risk of early death. The researchers believe the findings highlight the importance of movement, regardless of intensity. Participants wore activity monitors over a four-day period to record the intensity of physical activity. The death rate was tabulated through 2017 and this data was used to estimate how substituting exercise for time spent sitting would affect the risk of early death.
