F1 and VO2 Max Training

(x)(x)(x)(x)(x)

What is VO2 Max Training and why do drivers do it?

VO2 Max is the maximum amount of oxygen the body absorbs during exercise and can measure aerobic fitness levels. VO2 = Volume of oxygen consumed by the body per minute - it is one of the strongest predicters of heart disease and death. It is the best measure of cardiac and respiratory fitness available.

VO2 is measured in ml (of oxygen) / kg (body mass) / minute

How much oxygen the body consumes - the amount of blood the heart pumps per minute and how much oxygen was taken from it.

Now...why do F1 drivers need this?

Drivers put extreme demand on their cardiovascular, respiratory and overall physical health during races. Their bodies are subjected to enormous amounts of g-force and experience extreme heat and stress. They need a lot of energy to do this and as a result can burn a lot of calories per race.

VO2 max training is a useful measurement to assess a drivers endurance at their maximum during exercise which they are subject to during a race. The strain they're under during a race would require their bodies to be pushed to the max, requiring optimal oxygen intake and energy production.

It can ensure drivers are fit enough to endure the stress they subject their bodies to despite the environment within the car - maximum speeds/ heat. It gives drivers and their teams a greater understanding of how hard they can push their bodies and also how they can further maximise their performance during races.

Want to know a bit more about the science? Read below.

Now the (more) science-y bit - oxygen is used in respiration and as you breathe in oxygen the lungs turn it into energy called ATP (adenosine triphosphate). This powers the cells and helps release the CO2 in the body that's created during respiration when you breathe out.

The greater a persons VO2 max, the more oxygen a body can consume and the more effectively the body can use this to create the maximum amount of ATP energy and the better the body can handle aerobic/ cardio exercise.

During the test the goal is to get to maximum exercise to determine max heart rate, vo2 max and an estimated lactate threshold. The test measures oxygen consumption and CO2 production using a mask to determine values. The goal is to run at a comfortable speed but not too comfortable for around 10 minutes to max out oxygen consumption and heart rate. During the test heart rate is measured using the ECG dots you can see on the chest.

The Fick Equation is used to calculate VO2.

VO2 (mls O2/ minute) = cardiac output (stroke volume x cardiac output) x arteriovenous oxygen difference (difference in O2 content between arterial and venous blood - how much O2 is used by tissues in systemic circulation).

So in short, VO2 is how much oxygen the body consumes - how much blood the heart pumps per minute and how much oxygen was taken from it.

My first stress test ecg video is out now on OnlyFans! https://onlyfans.com/nathansheartbeat

Nathan had his first ever stress test today. He was kinda nervous about it at first but he loved how the suction electrodes felt on his skin...the mask for VO2 max recording made breathing harder but Nathan is a fit and sporty boy so he took on the challenge and gave it all he got...

So I got to do something I've always wanted to...

I finally got to get a vo2max test. Properly, in lab, mask and everything. No more estimating. And it turns out my vo2max is...

... still undetermined. I went for so long they had to stop the test because they didn't have a protocol for "finishing" their program haha. I'll admit I'm annoyed. I had just hit my anaerobic threshold when they stopped me at 25 minutes. At that point my vo2 hit 60 - which is already a standard deviation over average for most pro athletes. Extrapolating from various data points that puts the real number likely 75-80, but I kinda knew that and really wanted the lab established real thing.

The experience was pretty awesome though. Three people watched me take the test. The tech (exercise specialist) kept asking if I had symptoms and whispered to the nurse asking if I have a cardiac history, I realized after it was because my numbers were rising so slowly they thought maybe something was wrong. Turns out almost no one makes it to 15 minutes and no one in the room had ever seen someone finish. They did have someone get to 62 but he didn't finish the test, so a fun new weird bragging right is apparently my body is so efficient I don't just take in massive oxygen, I also use it better.

They brought in a fourth guy, another exercise specialist, to check the machine and they all spent the recovery asking questions about my athletic background and training protocol. They were all floored haha. I might be annoyed I didn't get the data I wanted but having a room of cardiac and fitness specialists grilling me cause my cardio blew their minds is pretty incredible, I'll take it.

Couldn't get pics during or with the ekg on but when they took it off my dumb ass said there wasn't any glue from the stickers. Woke up covered in rings and it took me like half an hour to scrub them off haha. I don't think they're very visible in the pic but I'm an attention whore so I'm obviously going to post pics of myself in my underwear after bragging about my heart.

1/13/24 Treadmill

Working on experimenting with different low impact ways to increase VO2 by increasing HR up into zone 5. Today was on treadmill, working up to a 5 incline and speed of 3.2 mph over about 10 minutes, then walking that for about 5 minutes. Treadmill is sooo boring, 15 minutes is about all I can handle. I'm a little more comfortable on the Treadmill today than last week. I did get HR up, but probably need it a bit higher and for longer.

[feverdreamsandlucidnightmares]

I had work and class today as usual, but I was very tired bc I got like 2 1/2 hours of sleep bc of poor decision making. And maybe that triggered a flare up, I have no idea. My blood oxygen level dropped to 91% this morning and my heart rate was, once again, dropping into the 40s every time I rested, but jumped up as high as the 160s when I was like taking stairs and shit.

So uhhh,,,I was tired as hell. I still am. Idk how accurate my phone is, but it says my VO2 max didn’t get above 24.6 today, which - if that’s correct - means my body was really struggling to use what oxygen I was getting. And the METs measurements indicates that I’m using as much energy to walk around and do normal tasks that a healthy person might use to run an 8-10 minute mile.

I still went to class. Which maybe counts for something, idk. But I apparently looked as shitty as I felt, bc multiple people asked me if I was doing okay. And one of my class friends checked in because I was apparently wheezing, which I didn’t notice, and it worried her.

It wasn’t a great day. And it’s far from the only bad day I’ve had recently. But, with the exception of some readings for my class tomorrow, I guess I’ve gotten through it. And I’ll definitely wear my leg braces and everything tomorrow so that I, at the least, don’t have to actively manage both issues.

But if anyone has any advice? Or like a hypothesis about what’s causing this? I’m not picky. And I’d be really grateful.

And I’m sorry for bitching about it on the internet again.

Late present I guess

Took all of 3 days off for the holidays and went for my first run back. I have ZERO idea why but my heart rate was WAY higher than it should have been. Dehydration, too much caffeine? Idk. I noticed on my warm up i was going like 140s where I should have been 110s. So naturally I started ramping on hills to see how fast my heart was willing to go. Kept up just under 180 several times, which is over normal max. I love how frantic my heart felt and sounded. What a little treat.

Milestone?

The Garmin minions have granted me an improvement in my V02 Max. As I finished my ride last night it announced, "Congratulations you are now 43 ml/min/kg."

My spreadsheet shows me at 46 to 47. The Fitbit thing says 45 to 49.

Two of these are based on a statistical method that uses resting and maximum heart rates. The Gramin does not know my resting heart rate so there must be some magic going on. Any of those numbers are very good for a walking fossil such as I.

VO2 max is a measure of either how much Oxygen you can push to the muscles, or how much you can pull from the air. Your blood is the commuter bus line for the O2 so if you have an efficient heart and lungs that is the pulling from the air part. If you have great capillaries in the muscles that is the other.

I have heard conflicting opinions on if it is possible to improve by training. One side claims you are born with it high or low. The other says you can train it. I think there is truth in both sides. If I were still a potato my VO2 max would be 30 ish? But real athletes have stupid high numbers like 80 ish and more. The current Tour d France champ has an estimated value of 97!

Greg Lemond had a rating of low 90s by actual test in his prime years. It varies with weight of course. If you get 10% lighter your VO2 Max is 10% better. Of course those guys are the definition of pointy end of the curve.

You can improve it by losing weight. You can improve it by cardio training. It is literally a cardio fitness measure. But reliable people say that it is mostly genetic. Heart capacity, lung capacity and muscle types all contribute. No Way I could ever have been over 60 even when young.

I just like the part where I can say I am as fit as a person decades younger than my true age. Of course what is true age? How many trips you have around the sun or how fit your body is?

It is a good number to have. Far more accurate than how many hours in a Gym per week, or even how hard the Earth pulls you down.

Thanks Garmin for the award. Now can you fix you stupid altimeter thing. It is never correct.

1/10/24 1.5 Mile walk with incline and stairs

Tried another tactic to get HR up more by climbing the stairs that lead up to the walk trail overpass. It worked to a degree, but it's only about 2 flights, so not long enough to get into PEAK zone. I also tried walking up the ramp, which took longer but still didn't do the job.

Trying to get into "zone 5" to work on increasing VO2 max. You can see the spikes in HR from each climb, which is good, but it's just not spiking high enough.
