Cardiorespiratory fitness (CRF) may be the single most important health metric for lowering mortality risk — yet it remains underappreciated in clinical practice. A study of 120,000 people who underwent exercise treadmill testing found striking results. When comparing the lowest CRF group to those just slightly more fit, the lowest fitness group had a 95% greater risk of death.
For context, having diabetes or a history of smoking was associated with about a 40% greater risk. The flip side? Those in the highest CRF group had an 85% lower risk of death compared to the lowest group. The data from this and many other studies support the same conclusion: the higher the CRF, the lower the risk of death.
"Not enough doctors or patients understand how important CRF is for their overall health," researchers note. "No other topic in healthcare has a greater potential to improve health at both the population and the individual level." Read more by tapping the link:
