At Horizon Longevity, we’re passionate about helping our clients live longer, healthier lives—not just adding years to life, but adding life to those years. And one of the most powerful tools we use to assess and support long-term health is VO₂ max testing.

But what exactly is VO₂ max—and why should you care about it if you’re focused on longevity?

What is VO₂ Max and why does it matter for longevity?

VO₂ max (short for maximal oxygen uptake) measures the max amount of oxygen your body can use during intense exercise. Think of it as a gauge of your cardiorespiratory fitness—how well your heart, lungs, and muscles work together when you’re pushing your limits. The more efficient your heart, lungs, muscles and blood vessels are, the higher the VO2 max, which is a key marker of both overall health and performance.

But VO₂ max isn’t just a fitness metric—it’s a strong predictor of lifespan. Studies have consistently shown that people with higher VO₂ max levels tend to live longer and have lower risk of chronic disease.

In fact, one landmark study published in JAMA Network Open found that cardiorespiratory fitness had a stronger association with reduced mortality than even smoking, diabetes, or heart disease.

Simply put: the higher your cardiovascular fitness, the longer and healthier you’re likely to live.

The VO₂ Max–Longevity Connection

Here’s what improved VO₂ max can mean for your long-term health:

• Better cardiovascular health
  A strong VO₂ max reflects a heart and vascular system that works efficiently, reducing your risk for heart attacks, stroke, and hypertension.
• Improved mitochondrial function
  Oxygen fuels our cells. Better mitochondrial function, as reflected by greater capacity for oxygen use, is optimized in those who maintain a high level of physical fitness.
• Lower inflammation and metabolic risk
  Individuals with higher VO₂ max tend to have lower levels of inflammation, better insulin sensitivity, and reduced risk for conditions like type 2 diabetes.
• Increased resilience with age
  VO₂ max typically declines with age—but the rate of decline can be slowed (and partially reversed) with the right training. Maintaining a higher VO₂ max as you age translates to greater physical capacity, independence, and protection against frailty.

Personalized Baselines and Measurable Progress

One of the most powerful aspects of VO₂ max testing is that it gives you a personalized baseline. From there, you can design targeted interventions—often including Zone 2 cardiovascular training, nutritional support, and optimization of hormone levels—to help improve your number over time. There is an expression: Your best VO₂ max is your second one!

VO₂ max is also measurable and modifiable, making it an ideal marker to track as part of a broader longevity-focused health plan.

How We Use VO₂ Max at Horizon Longevity

At Horizon Longevity, VO₂ max testing is a cornerstone of our comprehensive health assessments. We use state-of-the-art equipment to precisely measure your cardiorespiratory fitness, then you can integrate those findings into a data-driven, personalized longevity strategy.

Whether you’re an athlete looking to optimize performance or someone just starting a fitness journey, understanding your VO₂ max can unlock new levels of vitality and supported a prolonged healthspan.
