RUN SLOW, GET FAST | VO2 Max + Heart Rate Training Zone

[@Give_Me_Rent]

It's actually quite refreshing to see a lot of fitness youtubers slowly transition to more of a cardio based lifestyle. Heart health is very important

[@stargazerbird]

I am 70 and my VO2Max is 37 according to my Garmin, in the Superior range. Coming from Poor at 28 it feels amazing. It took me 3 years of running consistently two to three times a week. I still carry more weight than I need so I aim to improve further. Running becomes a big enhancer of life in all ways . Just keep going out and doing something. I lift just once a week. Keeps me strong enough.

[@mmholling87]

Great job! You're an inspiration to many!

[@billybarnett2846]

Got to learn how to pace yourself. That was biggest mistake when I was younger. I took advice from the movie Soldier. Run at a pace that I can maintain and be strong at the end.

[@XpVersusVista]

had a similar issue when i was younger. Was completely fit, all my muscles only from various sports like soccer, basketball, tennis, volleyball and sprinting. Body-fat of ~5% or below (i got blue lips even in heated pools after 30 minutes of moving). My issue was (or is) that i mostly have type 1 muscle-fibers. Massive explosive power but no endurance. It was for me as exhausting to run 8km/h as it was running 20km/h when trying to run longer distances. Everything I always did was quick explosive movements where fast acceleration and speed was important, but no continuous movement (Tennis is a good example of that)

As a bodybuilder who very recently started running and trying to be a Hybrid athlete it was again another confirmation as to why I get tired so fast when hearing that the muscle fibers that I trained for too long are prepared for short bursts of energy but when it comes to long distances etc I need to do a lot of Zone 2 running.

[@AlteredState1123]

Well done. Good topic. For distance runners, 80/20 might be where it is at: 80% steady state upper area of zone 2; and 20% zone 4 and 5 with various intervals. I am interested to see if alactic interval training (5 seconds explosive 30 seconds rest or something close to that) might be another route to condition athletes who require both speed and endurance (field sport athletes, wrestlers, boxers). Steady state zone 2 training can take a toll on performance in these sports, and lactic training can be very destructive when the dosage is not managed correctly.

[@gearsghoul4500]

Exercise Physiology is awesome. Thanks for the video Meg.

[@Shevock]

I'd love to do one of these tests to get my official numbers. According to my Garmin my resting heartrate is 56. My highest heartrate I've gotten on the chest strap was during a 10k, and that was 193. Here's the thing. I'm 47 years old and 195 lbs. I run mostly in zone 2, but not entirely and I lift weekly most of the year round.

[@Jotaris8436]

As an exercise physiologist thats administered these tests and taught it to college students, i have so much to say about this test, something of specific to note is (RPE) or rating of percieved exertion was not used during the test (or I did not see it being used) which is odd as it is a standard and if used more frequently by the person can be a better option than a monitor in most instances, the way the doc broke down the HR zones is no longer the scientific consensus- for instance aerobic vs. anaerobic metabolism and what works best for fat burning is a total reduction/loss in calories which could come from a higher intensity even if it is anaerobic and his anecdote for weight management is absolutely perfect but it works in the sense hes having them create a behavior of more total activity gradually over time instead of a focus on low intensity work which are different things. Another slight critique is he did not explain a "Peak" vs "True" VO2 ... that graph depicts a linear increase and then a drop at the end or a "Peak" however a "true" VO2 is achieved when the line plateus with an increase in work output or even better said the bodies entire mitochodria cannot work any harder to make ATP is what the plateu represents... a semi-recent change in testing methodology to go through this process includes a 5 minute low intensity walk/jog after that peak is achieved followed by an increase to that maximal achieved effort and ideally slightly more so that line would get closer to the "true" max.. while also stating an RPE between 18-20. I personally like to program set stages instead of a super fast protocol like this, a solid VO2 test can take between 8-12 minutes with stronger athletes doing a little more. I ask what the persons avg 5k time would look like as well their mile time and set the pace in Kgm/min to determine stages speed and grade (incline) and really only toward the final few stages do i change things on the fly as needed. However, theres another pending consensus change to set the speed and at a static value which has the person run and only increase incline in stages which has had great success in achieving a consistent "true" VO2 max.

[@Jotaris8436]

@@mossab8209 I highly suggest the NSCAs book for CPSS-Certified Performance and Sport Scientist certification that is the NSCA's Essentials for Sport Science. The book is meant for graduate students and it comprises much deeper information about the field as a whole. I would suggest learning as much as possible from many sources across all domains of biology, mechanics, and especially statistics. In particular, the more you understand about statistical analysis the better off you will be. However, with an exception to traditional stats folks, you MUST get as much field/lab experience as possible i.e. collecting data, interpreting and reiterating the hypothesis. The job markets still undervalue quality work in this domain unless you end up working for a professional sports team (which is far less than 1% of all sport scientists), to fight this, make your-self as knowledgeable as possible and set goals of topics that interest you specifically. Across domain books there are Advanced Exercise Endocrinology by Katarina T. Borer, Statistics for Sport and Exercise Studies by Peter O,Donoghue, Berne & Levy Physiology textbook (this one in particular is excellent compared to many other general anatomy books because it shows and describes mathematical formulas associated to physiological systems), Advanced Fitness Assessment and Exercise Prescription by Ann L. Gibson, Dale E. Wagner, and Vivian H. Heyword. Neuromechanics of Human Movement Roger M. Enoka, Ernsting's Aviation and Space Medicine (excellent book to understand acceleration physiology, hypoxia, spatial disorientation, thermal protection, vibration, and human factors). Biomechanics A Case-Based Approach by Sean P. Flanagan (probably the best book ive seen which integrates the physics of movement on a case basis, *note having a foundation in calculus is necessary to gain the most from this but there are concepts you can take away without the deeper maths knowledge). And of course lastly, become a member of multiple professional organizations as soon as possible learning from each while also using your time to participate in research studies until you gain the tools necessary to use in whatever setting you desire to be. I hope this help, and by no means is an exhaustive list 😅 I also absolutely recommend that you get as much time as possible with your schools testing equipment and learn everything you can about how it works and proctor tests + actually perform the test yourself to get a feel for what your participants go through.

[@iamsillycaitlin]

I’ve been following for a while although admittedly I’m more of a runner who uses strength to supplement running. If you get serious about running, having a tracker with a heart rate function (like a Garmin watch, or a chest strap that pairs with a watch) can be a game changer-you can set up pace, HR alerts etc., really helpful for targeted training. I’m sure there are other alternatives out there too. Congrats on your superiority!

[@mickthelick5788]

Totally agree with this. I have a Garmin Fenix 6 and pair it with a polar flow HR monitor for my treadmill runs. It is by far the best way I have found to monitor how hard I am really working when doing HIIT and LISS and ensure that I am being consisitant. Its really helped with my conditioning. To give you some context I'm 43 years old have a RHR of 45 bpm and a MHR of 191.

I've always wondered as a "trail runner" what my VO2 max is at 58 years old. I will run average HR at 155, and take it up to 178-194 for 15 minutes at a time on the steeper grades, then running down the hills at 165-175 hr. The problem with VO2 Max sports analytics is that on hills things are not always equal due to elevation gain/loss which is constant. So, I can never get a reasonable reading.

I'm one of those weight lifters but I'm an oddball weightlifter in that I have been doing zone training since 2012 ... lemme tell you something about v02max, I'm 52 years old and I test at 51 ..... one of the best ways to improve your v02max results is to train hard and train hard often (I mean really push yourself .... I'm an all or nothing kind of guy, I either give 150% or 0% and there is no in-between). If your watch says your max heart rate is (for 33 years old using the standard formula 220 - age)) 187 ... you need to push your heart rate into the low 190s and keep it there as long as you can and often. When you first start doing this, some people feel the urge to vomit .... thats a classic sign you are in the anaerobic level. Some people get that acid taste in their throats. The more and longer you train in that level, the longer you can go before those symptoms appear. The 220 - age formula is really not accurate though for people who work out often .... you should be able to go even higher. I test myself on a bowflex max, using my regular hiit resistance level of 10 and I push each heart rate zone recently 15 minutes per zone. There is actually a pic on my instagram account around 8/15 of this workout showing the zones and length of time I was there. But you can't just go 15 minutes per zone, you have to work up to that. I have only been training for 16 weeks after battling cancer for the last two years, my v02max level was in the low 60's and I am on my way back to that level of fitness....in another month or two. Also, increasing your v02max will make your resting heart rate much lower .... mine is currently 38.

[@sharpridgehomestead]

i forgot, polar is HUGE on heart rate zone training ... so if you are looking for a hrm, check out the polar h10 or get a polar watch with the h10 because they have programs specifically for runners (I'm on my 3rd polar watch since 2012 ... start with an ft60, then a v800, currently using a vantage v - I prefer the high end watches, they have more tests and things)

[@tilfliegel]

This fat burning at low intensity is irrelevant for weight/fat loss. Burn more fat during exercise and you'll burn more carbs later and vice versa. It does not matter what you burn during exercise and low intensity just burns less calories overall if you put in the same amount of time.

[@tonybowen455]

Not familiar with your channel, but looks like it's more gym work instead of running. Great vo2max for not being a runner. Not sure how much running you can fit in, but you might be able to improve it by quite a bit if you get into running. Prob cycling or rowing too, but yeah I'm biased.

[@listrahtes]

Its a nice game but not needed to specify your vo2max in terms of how to plan training. if you are a seasoned runner or cyclist. You go by RPE scale and mimik vo2max Intensity which you get a feeling about by intensity , breathing Rhythm and muscle activation. after several months. It is very accurate and can beat this setup. For cycling there is the 4 minute test with a powermeter...etc. And do a much longer warm up. The docs whole theory about fat burning is outdated by at least 10 years. Not someone I would choose.
