## Описание

This clip is from episode #379 - AMA #79: A guide to cardiorespiratory training at any fitness level to improve healthspan, lifespan, and long-term independence

In this clip, they discuss:


- Cardiorespiratory Fitness as a Modifiable Predictor – Identifies CRF as one of the most important modifiable predictors of longevity and quality of life
- Outperforming All Other Mortality Predictors – Notes that CRF outperforms blood pressure, cholesterol, BMI, smoking, and even age as a predictor of all-cause mortality—the “holy grail” longevity metric
- What CRF Actually Measures – Describes CRF as the combined efficiency of the heart, lungs, blood vessels, and muscles in delivering and utilizing oxygen
- Physiologic Reserve and Stress Tolerance – Highlights that higher CRF provides greater physiologic reserve, improving resilience to infections, surgeries, and daily stressors
- VO₂ Max as the Standard Measurement – Notes that VO₂ max is the most established and repeatedly used measure of CRF

Cardiorespiratory fitness is one of the most important and modifiable. It's very important that we're talking about modifiable predictors of both how long you're going to live and how well you're going to live. So if you look at all the predictors of all cause mortality, which remember that's the holy grail metric of longevity, cardiorespiratory fitness outperforms every other variable we can measure. This includes blood pressure. This includes cholesterol. This includes BMI, smoking. It even includes age, which just blows my mind. Cardiorespiratory fitness, CRF, represents how efficiently your heart and lungs and blood vessels and muscles can work together to deliver and utilize oxygen. The more efficient that system is, the more physiologic reserve your body has. And it's this reserve that allows you to tolerate stress. This stress can come in the form of an infection, surgery, or just, you know, frankly, the day-to-day demands of living. Now, this has been most typically and most repeatedly measured using a test called V2 max. You've heard me talk about this, of course, um, and it's become a very popular thing that people talk about. It's the maximum rate at which the body can utilize oxygen. Tested, of course, during maximal efforts, which require exercise. to put some context around the importance of V2 max and mortality again because it's been studied um if you're in the bottom quartile or um quintile so bottom 20 to 25% of the population with respect to your V2 max you've got a four to fivefold higher risk of mortality all cause mortality in any given year than those in the top 3% 2 to 3% so that's a that's a pretty big jump but keep in mind Even tiny little jumps, you know, say moving from uh the uh second quartile to the third quartile will still have uh easily a 50 to 75% um uh improvement in all-c cause mortality. — And then beyond mortality, can you also talk about the health span benefits? So what you refer to is not only how long it can help you live, but how well
