VO2 max – your physique’s capacity to move and use oxygen throughout intense train – is greater than only a measure of athletic efficiency. Lengthy considered the gold customary for cardiovascular health, this key metric, measured in millilitres of oxygen per kilogram of physique weight per minute (ml/kg/min), is now linked to one thing much more essential: longevity. New analysis reveals that these with the next VO2 max not solely carry out higher in endurance sports activities but in addition have a signifi cantly decrease danger of heart problems, hypertension, type-2 diabetes, and even untimely loss of life. In brief, boosting your VO2 max could possibly be probably the most highly effective methods to increase your life.
Well being and human efficiency specialist Dr David Lipman explains why VO2 max is such a dependable indicator of cardiovascular health: “It encompasses many physique methods. It reveals how a lot you possibly can breathe in and get out of your lungs to your blood and out of your blood to the muscle mass.” The upper an athlete’s VO2 max, the extra gasoline they will burn at their prime finish. “There’s a massive genetic part,” provides Lipman, “however it’s also trainable.”

Bettering your VO2 max in a bid to extend longevity is attracting increasingly mainstream curiosity. The query of whether or not the next VO2 max equates to an extended life is, in fact, compelling. Nonetheless, Lipman cautions that, on this occasion, correlation will not be causation. “I feel VO2 max is only a measure of the kind of way of life that can permit you to reside longer,” he says. “You probably have a superb, nutritious diet, good physique composition, a steadiness of quantity and depth, and a few energy coaching, it’s probably that you’ll have a excessive VO2 max.”
One research investigating midlife cardiorespiratory health and the longterm danger of mortality, printed within the Journal of the American Faculty of Cardiology in 2018, explored the function performed by bodily health in longevity. The research tracked the connection between VO2 max and mortality amongst 5,000 middle-aged males over 46 years. The outcomes confirmed that every unit improve in VO2 max was related to a 45-day improve in lifespan. These with the best health ranges lived nearly 5 years longer on common than their much less match counterparts. The research’s lengthy length and huge pattern dimension make it a persuasive piece of proof that VO2 max isn’t only a measure of efficiency however a strong predictor of longevity too.
Even so, establishing a causative hyperlink is difficult. Excessive VO2 max is usually associated to constant bodily exercise and a typically more healthy way of life. A way more current research, printed final 12 months within the Journal of Scientific Endocrinology and Metabolism, sought to unravel the advanced relationships between VO2 max and elements together with physique composition, bodily exercise and longevity. The research highlighted the significance of different way of life and genetic elements reminiscent of lean muscle mass and bodily exercise, and concluded that, regardless of being a powerful predictor of mortality, VO2 max will not be causally related to longevity.
“VO2 max is measurable and quantifiable,” explains Lipman. “It’s an output measure, making it a superb indicator that the entire system is in good order.” Maximal oxygen replace is an interesting determine to trace for anybody specializing in bettering their cardiovascular well being, however longevity is set by a posh interaction of many elements. “There are different stunning predictors of longevity reminiscent of grip energy and leg energy,” provides Lipman. Identical to VO2 max, these benchmarks probably correlate to longer life as a result of energy is one a part of the longevity jigsaw puzzle.

Decline or disuse?
VO2 max naturally declines with age, sometimes at a price of about 1% per 12 months after age 30. This decline is basically as a consequence of physiological adjustments that happen as a part of the ageing course of, reminiscent of decreased cardiac output (the quantity of blood pumped per beat), lowered muscle mass and decrease pulmonary operate. Nonetheless, it may be onerous to differentiate between the consequences of organic ageing and the consequences of lowered bodily exercise. “It’s a case of use it or lose it,” says Lipman, explaining that VO2 max declines extra slowly in those that proceed to coach.
Length versus depth

A research printed within the Journal of the American Society for Preventative Cardiology in 2007 revealed how managed endurance train impacts cardio health amongst older adults. This meta-analysis of 41 medical trials involving 2,102 individuals aged 60 and above explored the consequences of cardio train on VO2 max. The outcomes indicated a average however significant improve in VO2 max, translating to a web enchancment of 16.3%. The most important features accrued to these whose train programme prolonged past 20 weeks and who educated at an depth of 60- 70% of VO2 max.
Lipman urges warning: “A lot of the analysis on older folks makes use of sedentary people. Coaching standing is tremendous related in such research.” In different phrases, untrained folks discover it simpler to make vital enhancements. “Most individuals can improve their VO2 max from the decrease finish of the vary if they’re untrained. Nonetheless, in case you are already extremely educated, there may be much less room for enchancment.” The excellent news is that, whether or not you’re new to train or an skilled athlete, you possibly can enhance or keep your VO2 max via coaching.
“There are two kinds of coaching you should use to spice up your VO2 max,” explains Paul Vousden, proprietor of endurance sports activities gymnasium Strength2Speed. “Within the absolute easiest phrases, you want low-intensity exercise the place you’re a little bit out of breath for a very long time, or quick however very onerous efforts.” In Vousden’s view, whereas youthful riders may give attention to boosting their cardio health with lengthy Zone 2 rides, a greater route for veterans is shorter, sharper intervals. “Older riders who’ve been coaching for a few years have already got an endurance base, so the give attention to quick, onerous VO2 intervals permits them extra time for restoration than in the event that they had been doing lengthy, regular base mileage.”
It is a vital level, because the physique’s capacity to get better decreases with age. However does decreasing quantity and rising depth actually work? “We now have shoppers right here who focus purely on VO2 max and energy,” says Vousden. “One member is a GB duathlete and has very efficiently continued to race properly into his sixties.”
Holistic method
Does Lipman agree with this shorter, extra intense method? “From a efficiency standpoint, you want excessive and low depth,” he says. He factors out that, at a inhabitants degree, most of us should be shifting round extra – be it strolling, biking or jogging – at a low depth. “It could possibly be that quick doses of excessive depth are extra essential for sure folks – if you happen to solely have very restricted time, excessive depth is the best way to go.”
Whereas sustaining a excessive VO2 max can contribute considerably to more healthy, extra resilient ageing, longevity doesn’t revolve round this one issue. It’s true that having the next VO2 max is related to higher well being outcomes, however genetic elements, way of life decisions, environmental influences and entry to healthcare all play a component in life expectancy. To reside as healthily as doable for so long as doable, we have to take a holistic method that encompasses energy coaching, consuming properly, sustaining good physique composition and taking care of our psychological well being. Nonetheless, it’s good to know as we’re smashing out these onerous reps on the turbo that sustaining a excessive VO2 max can undoubtedly contribute to a more healthy, longer life.
Can your V02 max be too excessive?

A excessive VO2 max signifies that you just’re in a sturdy state of cardiovascular well being. Protecting it excessive requires numerous coaching: both plentiful miles or frequent high-intensity periods, ideally each. However in specializing in sustaining VO2 max, are you able to go too far and compromise well being and doubtlessly longevity – by overdoing it?
The analysis means that, sure, that is certainly a danger. Whereas common cardio is strongly linked to longer life, the next incidence of coronary heart issues reminiscent of atrial fibrillation and scarring has been recorded amongst athletes who’ve undertaken very high-volume, high-intensity train over a few years. Some specialists even have issues regarding the oxidative stress which will end result from extended excessive depth work. Whereas average train is anti-inflammatory, extreme endurance coaching could suppress immune operate and improve irritation.
A 2015 research printed within the Journal of the American Faculty of Cardiology supported the speculation of a ‘U-shaped curve’ whereby the bottom mortality danger corresponds to average ranges of train however will increase in the direction of the very excessive finish of the amount axis. Gentle to average joggers had been discovered to have the bottom mortality danger, whereas excessive runners had comparable mortality charges to sedentary folks.
Broadly talking, 75-150 minutes of vigorous train per week is taken into account optimum for most individuals. Repeatedly exceeding 10 hours per week pushing above average depth places you into the zone of probably undoing the well being advantages via extra.
TESTING YOUR VO2 MAX

Modifications to VO2 max take time, so there may be little level in testing ceaselessly. “Understanding your VO2 max will not be related by way of setting your coaching zones,” says coach Paul Vousden. If you’re following a power-based coaching schedule, it makes extra sense to do a easy FTP check [a test of your Functional Threshold Power, the power you can produce over an hour] each few weeks. Even so, VO2 max is a nice-to-know determine to have measured sometimes.
Probably the most correct methodology of testing your VO2 max is with a graded train check in a lab setting, with a educated technician capturing and measuring expired respiratory gases. Many health trackers and smartwatches provide VO2 max estimates primarily based on coronary heart price information and exercise ranges, however the accuracy is low. Wearable gadgets could be helpful for monitoring developments in health over time however deal with their VO2 max estimates with warning.
Aware that it had been not less than a decade since I final had my VO2 max check, this characteristic offered the proper incentive for a re-test. Having not adopted a severe coaching for the same size of time, I used to be curious to learn the way a lot harm had been executed. I visited Mapdec Cycle Works in Kendal, the place proprietor Vousden put me via my paces with 18 minutes of masked-up torture. “There isn’t any level ready till you’re match to get examined,” he reassured me. “You should know the place you’re ranging from.”
my numbers, I cringed at my peak energy, a wattage I used to heat up at, however I used to be delighted to seek out that my VO2 max had remained good, at 53ml/kg/min – a determine classed as glorious for my age. My temporary second of smugness was quickly brushed away as Vousden jogged my memory that VO2 max alone doesn’t equate to race-winning efficiency. “Utilizing VO2 max as a measure of normal well-being is extra essential than your lactate threshold or your energy output,” he started diplomatically, “however if you wish to be aggressive, we have to see some enchancment in energy output.”
