I am 66. A road cyclist and occasional racer. Peak VO2 Max last year was 68. My VO2 max has been 65- 68 for the last 10 years. My training plan is quite simple. Year round, each week I do at least one and as many as three base rides of three hours or longer (Zone 2 in the 5 Zone model). In addition, each week I do one VO2 max workout. For six weeks in the spring I do two VO2 max workouts per week. That 6 week block of 12 workouts really gives my power a boost heading into the outdoor riding season. During the riding season I add one very hard group ride each week. The race like intensity of the ride is what I train for. That's it.

Recently starting using Zwift as I'm enjoyed rode riding immensely. Would like to see my VO2 max in the high 40's. Can you share more details what a VO2 max workout looks like?

Once a week I do four 4-minute intervals on the stationary bike with three minutes' rest between intervals. I try to hold 300 watts for the intervals, but often fail to manage this. In your opinion, what would be better: One interval workout per week as I just described (four intervals with three minutes' rest in between), or two intervals workouts per week, but in those two workouts, do three intervals instead of four? .

2:10 "The device used to measure my VO2 max" - there's your error. Garmin watches don't MEASURE your VO2, they estimate it. More correctly, they over-estimate it. My Garmin watch estimated I reached 57. Great. A lab test showed 50. The lab technician before the test even said they expect it to be over-estimated based on their industry experience. I have very accurate power meters on my bicycle so I know my FTP, which lines up with my lab measured VO2 max (and estimation tables), not my Garmin over-estimated figure.

Nice to meet another "super senior"!!! I am almost 66 years of age and cycle 80 to 100 miles/week. I include HIT training in my weekly cycling plans. My VO2 max is around 50 - 51 at the moment. It seems to have peaked here for the past year.

Get a real Vo2 max test and just use your watch to look at your delta/changes. My Iwatch was totally unreliable on the low side which prompted me to get tested. So many confounds with an algorithm.

I have four separate Garmin 945xt watches (picked them up cheaply as people upgraded). Each one gives a different VO2 max, there is about a 10% difference between highest and lowest.

I am 58 and recently crossed into the HIGH category as defined by apple. When I got COVID, it went down to 28.5 and 2.5 years later it is 41. I alternate between doing a hard swim for 800 yds, swim intervals for 900yds and do a paced swim for 1500yds trying ot make every 100yds the same or speed up towards the end. I do this 4 days per week and I will walk the dogs for 3+ days per week. when I hike in mountainous areas, I can walk quickly with ease on trails with 1000' vertical gain and 8 miles long. While throwing walking into the training regime may seem kind of lame, I find it really helps with general joint strength and will serve into my 60's, 70's and beyond. My end goal is to be able to hike to base camp of Everest in my 60's. I consider a 41 V02max to be one of my biggest achievements. Now that I am here, I am ready to take it to the next stage!

I'll report my progress on May 6, the day after my marathon 😉. Be well.

[@takatsu5]

As a competitive runner, it is common knowledge that "VO2 Max" training means a track day with some combination of 400m or 800m repeats. The ironic thing is other psychologic adaptations such as lactate threshold or running economy are much more responsive to training. Elite marathoners are born with higher VO2 maxes, and we mere mortals can never train to their level. However this shouldn't discourage us as we should seek to maximize our own potential. I would argue too that the goal is the doing the hard workout and not worrying about the number.

[@mertonhirsch4734]

And marathon runners tend to have higher mortality than mid distance runners. VO2max above the 75th percentile has very low added effect size, about 3% of the effect of going from 25th to 75th. I worked at a major sports research university and we found no health benefits from running more than about 30 miles in a week on average, and a downslope after that, and at 60 miles per week the mortality rate had risen back to that of a sedentary individual. This was a meta analysis with over 300 elite runners.

[@takatsu5]

@@mertonhirsch4734 For elite runners, I'd believe the higher mortality, but a meta analysis of 300 elite runners being applied to all marathoners is a big stretch. Elite runners aren't too different than other elite athletes, who also have relatively high mortality rates, since they push themselves really hard, a lot harder than the vast majority of those who run and complete a marathon or two. Even among those I know who have qualified for the Boston or New York Marathons, they might peak at a few 60 mile weeks in their training buildup, but that is just a base week for the elite crowd who may run up to 90-110 miles per week for months.

[@mertonhirsch4734]

Like many seniors, I retired at age 65. During my first year of retirement, my goal was to improve my overall health, and maximize my fitness level. I never set specific markers to measure both my progress, and ultimate achievements. Like most of us, I considered both feeling better, doing more without fatiguing, to be adequate measurements. I also thought an improved overall appearance would be a good indicator. I just had my 66th birthday. Did I succeed? I do feel better. However, I started the year, in critical condition. And a few people have said I look better. However, I interact with only a handful of people. Luckily, I purchased a Fitbit to measure how much walking I was doing. I began walking a lot. Then incorporated resistance training into my routine. I averaged five gym workouts per week. Ultimately, now the most important question is.........can I perform physical activity, both better, and longer? Another question is....... will I live longer? It seems to me, that a slim waist, bulging muscles, explosive strength, and blazing sprinting speed, are not definitive indicators. Because, I have none of the above. Although, I have a bit of each. What I do have, is what I consider....... SCOREBOARD. Both my Resting Heart Rate, and VO2MAX, are .....52!! It's no surprise, hi I can complete an ultramarathon on a whim, and almost never get sick, or fatigued. I just don't understand why so many non athlete people, particularly seniors, get caught up in total weight lifted, speed, calories, steps, appearance, etc. It's logical those could be great motivators. And ultimately, it will improve their own scoreboard. Nevertheless, I just feel those things don't guarantee better health, and a longer life. Whereas, the scoreboard I mentioned, are probably the most relevant factors. In my 66th year, I plan to focus solely on the scoreboard. I will continue to target factors like focus, form, efficiency, consistency, and most importantly, maximum effort during every workout. All adjustments to my speed walking, and HIIT resistance training will be toward improving my scoreboard. Not winning races, competitions, or looking better in a mirror. I wish there were more YT videos, and podcasts focused on individual scoreboards. Unfortunately, our society seems to be caught up in appearances, rather than effectiveness. What's your goal? What are your tracking indicators for measuring progress? And what's your scoreboard? Here's a link to charts for both RHR, and Vo2max. Look up where you're at. Thereafter, I'd appreciate your thoughts on this topic. **Update edit. I just had my 67th birthday. My vo2max improved to 55 and my RHR improved to 50. This may be my lifetime peak. I hope not. www.tres.in/health-insight/resting-heart-rate-rhr-and-why-it-is-important/ runninforsweets.com/vo2-max-chart/

[@lollorosso4675]

Thanks for the links. The VO2max link was very interesting - though the calculation for VO2max (max heart rate / resting heart rate)x15,3 gives results that are completely at odds with what my Apple Watch tells me (which also is the source of my average resting heart rate). My watch tells me I am as good as dead (VO2max in the very poor category) while the above calculation puts me at average VO2max. I wonder how the difference arises. Luckily, my stamina when doing sports suggests the latter value to be closer to the truth.

[@IaintAI-m9d]

​@@lollorosso4675there are so many different devices and methods to measure vo2max, that it's difficult to get the true measurement.

The only way to accurately measure VO2 max is at a hospital or professional sports facility. Portable devices such as those being utilized are woefully inaccurate for a multiplicity of reasons. Some detailed research will elucidate my statement. The results achieved are very, very generous. I am sure most people take their health seriously and do not wish to be deluded. As such, I would suggest doing the testing correctly. The numbers I see cited here are quite out of the usual range for most people, when factoring age. Don't trust an anonymous KZbin commenter, however. I encourage you to take the initiative. The more accurate result may be quite sobering.

[@JustBrowsing777]

Actually Garmin watches have been shown to be very accurate in their estimated VO2MAX scores providing you have been using it for a while and with a cheststrap. Say what you will. Most of us don't need anything else anyway.

[@bilgyno1]

It seems to me there are two factors determining VO2max: metabolic efficiency, but also weight (given the fact that it is measured per kg of body mass). So, logically decreasing bodyweight will impact VO2max quickly for certain people without necessarily improving the aerobic fitness. Not saying it's not a good measure, but always need to look at the totality of metrics. And of course, losing weight is a good objective for many people.

[@jb_1971]

I think bodyweight has no bearing on the VO2Max, but it does influence indirect tests used to measure it, hence they are imperfect.

My watch says Vo2 Max. 34. Which seems low for my age. I cycle ALOT for years, mostly in zone 2(100-120bpm). But my watch only measures Vo2Max while running for a certain amount of time. I started running for the first time and it felt hard because it was new for me. I wonder how accurate these watches really are. I've also seen a youtube vid. of guy who had 61 on his Garmin, then went to lab with oxygen mask on a treadmill and he had exactly 50! That's 11 points difference. You should really do a Vo2Max test at a lab.

Hi Mark, thanks for sharing. I would be interested to do that, as a check on how accurate my current reading is and also for the experience. But so many other things to check, not sure when I will get the time!

[@lectrix8]

I worked in a human performance lab at my university during undergrad and own a Garmin Forerunner 935. So I've compared both. My watch usually underestimates my VO2max an average of 5pts from my actual VO2max. I'd say the higher end sport watches ( don't use apple and Samsungs) do an adequate job. The quality of the estimate can be improved if you use a heart rate monitor chest strap and perform workouts specifically to test you VO2max instead of just going by what your training volume and performance tells that watch. Also, there are behavioral factors that reduce the reliability of a VO2max on a watch. If a person pauses their run on the watch to artificially maintain a avg pace, that likely introduces errors into your results over time. If your bmi changes and you aren't diligent about updating that parameter in the app, then you'll introduce error because the calculations factors your mass in kg.

So I conclude that age should not be as big a factor for VO2 max as the charts say for the active senior who has exercised all his life. My heart has not aged as much as my knees have, requiring that I use a trampoline instead of running.

This may help those who, for what ever reason such as lower limb disability or arthritis, cannot just go out for a run. I'm 63, and am now paying for a miss-spent youth on motorcycles, Karate, HM Forces, then Farming, that all involved heavy physical work and a lot of lower limb and other damage. So, I can just about hobble around, but running is simply not on the menu. To get around that, I use a Static Rowing Machine, and row well for around 15 minutes a day, broken down into 5 minute sessions, with a 30 second HIT at the start. When younger, I used to do intense 30 minute sessions, so am aiming to pick things up again to manage that time. Last year I needed major Colon Cancer surgery, so had to get as fit as possible ahead of that. The Rowing did the trick, and when I went in, or should I say, hobbled in, for the NHS Pre-Surgery Fitness Test, I surprised the anaesthetist who conducted the test by producing a surprisingly good result on all fronts. The NHS Test is effectively a super VO2max Test, so uses a variable load Static Bicycle, as well as an ECG, Finger Tip oximeter and also an Oxygen/CO2 Measuring Mask & Pipe, all linked back to the controlling PC. You have to cycle for around 15 minutes, keeping up as steady a pace as you can, as the equipment gradually increases the load. At the end, you get to see a variety of graphs, and they can see things like the Aerobic to Anaerobic conversion point, and also how heart rate coped as the load increased. Anyway, my point here is, even if quite disabled, look for any equipment you can manage, that will allow you to do around 15 minutes a day, without extreme pain. Then add a HIT push at the start of every 5 minutes, and keep that up for 30 seconds. If you can, wear a chest strap and monitor your heart, and stick to set heart rates based upon age and start fitness. Such as a maximum during a HIT session above which you must not go, and then a good coasting rate for the other 4.5 minutes. At the start of each 5 minutes, push hard and keep that up for 30 seconds, but if your heart rate goes above the maximum, then back off until it comes down, and then next time, try to keep below the maximum. Then in the 4.5 minutes, back right off until your heart rate drops to your target rate, then row steadily trying to keep your heart at the rate. By working to your own heart, this is self-regulating and safe. Over time, if you can also monitor your average heart beat for the whole 15 minute session, and if the Rowing Machine can also count Calories burnt, you should see a gradual improvement. After a few week, I was burning more Calories, at a lower average Heart Rate. That is fitness in effect, and should be reflected in your VO2max, if that can be measured. Thankfully, I survived the surgery!

Congratulations! You are the first comment I’ve read that admits GENETICS are the primary determinate of VO2 Max. I’ve been an elite endurance coach for over 30 years. Research has shown that some athletes do not increase their VO2 Max number at all regardless of training. But they do increase their work capacity and endurance at VO2 Max (actually much more important). Generally, VO2 Max is hard to move at all, whereas for example you can greatly increase sub-max (threshold or endurance) quite a bit with training. And even lab testing isn’t necessarily accurate as real VO2 lab people will tell you. Some people are bad test takers. So again, thanks for stating the elephant in this room. Magnesium? Doubt there’s any study showing how it affects VO2 and I seriously doubt it does. Training at VO2 Max is important, but there’s no reliable way to measure its effect. For instance, this person claims a VO2 over 50. I’d like to see his TIMES. Running times. For example, his mile time. That is, output at VO2 Max. That would help us understand a bit better where he is in terms of output or wattage at VO2. 😊

Magnesium Breakthrough - there are a lot of things wrong with it. First it doesn't have Magnesiul L-Threonate which is the only magnesium that crosses the brain barrier and this is excluded. The other 7 magnesium ingredients it's hard to tell exactly how much percentage wise one is getting and plus not all of the 7 magnesium are necessary. It's not about quantity but quality. They just needed at least 4 different types of magnesium and L-Threonate should always always be included. Magnesium Breakthrough is extremely expensive also £29 (for just a month!) and because of these points not addressed I'm no longer optimistic about the product and am not purchasing.

I'm 66, and got up to a Garmin V02max estimate of 61. This was based on doing EIM (Easy Interval Method) training 3 or 4 times a week with steady recovery runs on the other days. One is very similar to your 4x4 minutes - it's 6x1000m with 800m steady/easy run recovery (if on track) or 6x4 minutes with 4 minutes steady/easy (if on road). Other sessions are 3x2000m with 800m recovery (or 3x10 min with 5 min steady recovery), 12x400m with 400m easy/steady recovery and 16x200m with 200m steady/easy recovery. I also did the occasional session of hill sprints. Recovery days were 3 or 4 miles in the 7:50-8:15 per mile range. Overall it looks not too dissimilar to what you were doing.

VO2 MAX is a very good measurement but has one flaw: If you gain weight due to more muscle you will theoretically have a higher VO2 MAX than if you gain weight due to fat. Not part of the equation similarly to the BMI index. A slim person will thus have a correct high VO2 MAX as compared to a rower/martial artist etc where the VO2 max will erroneously indicate lower. Musclemass is good for longevity, so a more muscular older person could hence theoretically be healthier than a slimmer person with a slightly higher VO2 MAX. Minor detail to your excellent video😊

[@mertonhirsch4734]

Resting heart rate is a very close, age relative estimator of VO2max. In your early 50s and with a VO2max of around 50, your resting heart rate should be in the high 40s, about 48. Also, being in the top 25th percentile for VO2max is a good predictor of longevity but there isn't any additional predictive benefit of being above the 25th percentile that I have seen. That would be at about 40. At above 40, muscle strength make up all of the lifespan predicted margin which may be why there is not any benefit seen for people above about the 75th percentile in VO2 max, because they may be trading strength for higher VO2max. At above about a 40 VO2max, it is more important to be able to do a deep squat, for example with at least up to 1.5 times your bodyweight on your back than to further raise your VO2 max. Upper body strength is also helpful for longevity. On standard is to be able to perform 50 pushups in a minute and to be able to do 10 pullups with an overhand grip to get the chin over the bar. These have much more marginal predictive power once you reach the 75th percentile in VO2max. That harms of having a low VO2max is much more profound than the benefits of going from above average to high, and going from high to elite is significant, but has a tiny effect, like 6 weeks EASILY outweighed by factors like upper body strength and lower body strength.

[@ebarr9476]

I say just get tested and use the peripheral gear for delta. My IWatch was way off. I agree with your strength point above cuz body weight really changes the score and as sarcopenia sets in strength efficiency also goes down. I'm 190, 5 10' and wear a 34' pant and a huge MTN biker (300 moving hours in 2022) and I lift and do yoga too. Seems my performance in those 3 realms is not that great and maybe I should be happy with that at 58? Lab measured vo2 is 38, I can do 6 chin-ups and can maybe bench 190lbs. Record at 26 was 305lbs.

[@marcdaniels9079]

That’s a lot of claims right there… seems like you have swallowed all of Peter Attias patter. None of this is well enough researched or understood yet to make the claims you have with any level of confidence. The only actual predictor of longevity so far agreed by the scientific community is calorific restriction which modifies the DNA.

[@Redtopper02]

I am not a gym goer but from my experience what % of men over 60 can do 10 pullups with overhand grip straight? Less than 4% probably. 50 pushups in a min is easier to accomplish but over 60 less than 10%?

[@colinfitzgerald4332]

I am using an Apple Watch latest series for tracking VO2max. I’m in the reported average range with a slow but steady VO2max improvement over the month.

[@nicolasbauchet7166]

[@miketracy9256]

GOOD ADVICE AND AS ALWAYS DOING A VARIETY OF INTENSITY AND DURATION MAKES SENSE. ANOTHER WAY TO MEASURE IMPROVEMENT IS IF WE CAN RUN 800M FASTER TODAY THAN YESTERDAY FOR THOSE UNDER AT 35. IF WE CAN NOW RUN 800M AT AGE 75 AND ARE SLOWING DOWN BY ONLY 25% (FOR EXAMPLE A 2:30 AT AGE 35 TO A 3:20 AT 75) WE ARE DOING QUITE WELL. THAT USUALLY REQUIRES A BODY WEIGHT REDUCTION OF ABOUT 20% FOR MOST OF US.

[@SMarkGee]

vo2max is based on bodyweight. oxygen consumption is almost entirely through muscle. if you simply gain more muscle at the same weight your vo2 should rise. that aside, i agree with much of what you say. your 4x4 can be improved by reducing the recovery to a more dynamic one, you'll probably find that your muscle oxygen recovers in about 90 seconds and if you wait much longer your will stimulate hypertrophy which you might well not want

[@RayT314]

But when I gave up just the deep breathing exercises, my V02 nose dived back down lol.

Since you have determined your VO2 max in a lab, you would be a perfect person to test something. A U.S. Air Force doctor, Dr. Kenneth Cooper, used thousands of military men in the 1960s and discovered the following test which closely correlated with VO2 max. 1. Go on to a running track. 2. Warm up by jogging five to eight minutes. 3. Run as far as you can in 12 minutes. 4. Take note of the distance you ran, in meters, during those 12 minutes, then use this formula: VO2 Max = (Number of meters run - 504.9) / 44.73 Because your VO2 Max is a known 64.6, that would equate to running 3,394 meters in 12 minutes. So on a 400 meter track that would be eight laps plus 194 meters. It would be interesting to see if what is valid with young military men also is valid for members of the general population. Since the military men he tested weren’t dedicated runners, their fitness came from their required calisthenics and physical training. And in the 1960s they didn’t have running shoes like today’s. I suspect that trained runners have better running mechanics which improves running efficiency. So if you are a runner, it may be you will achieve more than 3,394 meters in 12 minutes. But it would be interesting to see how close your lab results correlate to Dr. Cooper’s research.

@@ModernHealthspan It does! I remember staying awake while the rest of the family slept so I could watch it. The Drive and Found My Fitness are my two favourite podcasts about longevity: I listen to your's sometimes, but it's in short pieces and I like long podcasts while I exercise so I usually just catch you on KZbin. Just reading about NAC yesterday. Have you considered taking it?
