Hemoglobin: The Forgotten Limiter to Cycling Training & Performance

[@pjetrs]

You’re really on a roll with your channel lately, absolute gold Thank you

[@EJGilb]

The Hb to watts correlation is huge. I can literally use my power meter to tell me when I'm getting Anaemic. For context, I have UC (Ulcerative Collitis). I tend to slowly leak blood, and I can't get enough dietary iron (Iron tablets make symptoms worse). So when I detect my threshold starting to drop even by 10-20w I will get a blood test and often have low ferritin. Then they give me an iron infusion and my Hb shoots back up to ~140 within a few weeks. This happens once or twice a year.

[@vr4966]

I leave this up to my soigneur.

[@ricf9592]

I was diagnosed with low iron levels. I was given iron tablets and noticed a difference in about two days. VO2 Max currently 80.0

[@peecee1984]

My hemo is 120. Have coeliacs. Iron is mid range. Any tips?

[@EJGilb]

@@peecee1984 I'm not a doctor, but it could potentially be that you're losing blood a touch quicker than your body is able to replenish up to full red blood cell count. Being really strict with the diet and fully eliminating gluten may be your best bet if your iron levels are showing ok. If you have already, it could be something else.

[@peecee1984]

@EJGilb thanks for that. Yes, I do find being extremely strict on diet is best for me. Great point. I will look into possible blood loss reasons. 👌

Great advice Jesse! I’m a GP in the Gold Coast and some of my patients are athletes that we test regularly for these sorts of things along with monitoring for underlying disease that might impact performance.

[@philadams9254]

Good video. Water and carbs are the most crucial here and why people often say they lose power when losing fat - they're cutting carbs and tanking everything, especially if huge calorie deficits are involved, destroying recovery. The heat training protocols work because they push your plasma (water) to the limit and make the body increase the volume to compensate. You really need to stay hydrated for that to work though. That volume dilutes the red blood cells but after about a month more EPO is generated to balance it out.

[@kerolah]

I recently had my blood work done and I couldn’t believe my hemoglobin and RBC were both on the low end of the spectrum. I ride so much I thought it would be at least normal ! Great video.

[@wisskier]

I had this problem too. Nutrition I do believe was the thing that fixed my blood quality. That nutrition problem also led to illness and crashed training. Once I started nourishing appropriately and all of those problems went away.

[@RB-xv4si]

He kind of went over this in the video, but not super clearly. What you experienced is normal. Hemoglobin is measured as a concentration (mg/dl where I get my blood tests). So one thing to understand is that total blood volume and hemoglobin often do not increase linearly. Even though you likely have increased your total hemoglobin mass in your circulating blood, your blood plasma volume has increased even more than your hemoglobin. So on a test that measures its concentration, it’s showing as a lower concentration in the normal range. But if you were to get measured on one of those fancy machines this guy mentioned, it would likely show a total hemoglobin mass on the higher end, assuming your body is responding to your exercise as it should.

[@heikkisanelma6625]

Due to my medical condition i take ~4 times a year basic blood screen, Hb is unchanged in long term trend between 135-145 for 20 years. in the last 3 years of these i have a 580-620hr annual years of training of which 90-92% is aerobic training for half and full ironmans. 4 years prior to that the training volume was 450-550hr with little more bias to strength and conditioning, but still majority of full spectrum of aerobic triathlon training.... the 13 years prior to hat is more or less 350-400hr annual hoiurs with some interval running and mostly anaearobic and astrength bias cross training in the gym... body seems to refrain in the selected homeostasis in the biochemical status, but for sure the plasma volume is way up now, thus larger mass of Hb... and this is why heat training can help aerobic adaptations...

[@heikkisanelma6625]

just my empiric observations for over two decades

[@durianriders]

Using sufficient anabolics got me same 20min watts riding 50km a week than when I was doing 1000km a week. The boost you get from extra hemoglobin is NIGHT AND DAY and the more trained you are the bigger you will feel it. That is why we see such crazy spikes in performance in running, swimming and cycling at certain times of the year - BOOSTED BLOOD vs NATTY BLOOD. IYKYK. Guys like JC if they did my protocols fully and got on the same stuff the big names are on would be right up there with them or beating them. There isnt much difference inside but it is what you add extra or leave out that makes the difference at the top when everyone has pretty much the same engine genetics.

For many years doctors always asked me if I was taking something. Never understood why until they called me up twice after blood tests when I got covid. The doctor asked the same questions. But this time the female doctor told me why, because my blood values are so high. Hematocrit: 0.52 Hemoglobin: 180 g/mL This more or less backs up why I've always had it easy for endurance training.. Combined with a lungvolume between 6,5-7 liter. But sadly got asthma so avoid max sprints and focus on endurance.

Do you happen to know how accurate your finger prick hemoglobin tester is? Bought one after watching this but my results are all over the place. Super inconsistent even with as little as 5mins between tests. Not sure if it’s my machine in particular or if these style of tests are just not very accurate. Ps I don’t squeeze the finger and I make sure my skin is clean and dry.

[@nerocoaching]

The meter itself is accurate, the inconsistency comes from the blood sample. Needs to be a strong finger prick with plenty of blood flow to get reliable results. With a good sample I can get it consistent. It's useful in testing athletes if they haven't had a blood test to make sure Hb is in the normal range. I've found my Hb is stable so personally am not regularly using my meter

Great content and interesting approach! What's your thoughts on regular blood/plasma donation? I've been giving plasma every 2 weeks and constantly riding around 400km/week. Feel like the 'fresh' blood plasma the body produces after each donations, helps maintaining the stamina. Plus Redcross gives a free Hb check every 2 weeks. :)

[@nerocoaching]

That is a fantastic service you are doing by donating blood. But a big stress on the body to regenerate that blood and not good for performance unfortunately. In the study I was quoting they stopped doing the blood analysis within 4 months of the world record attempt because they didn't want it to impact training

[@tomghc]

I personally switched to donating platelets/plasma because donating blood was having a noticeably impact on perf for more than just the day of/day after.

[@trunx168]

@@nerocoaching sorry it's plasma, not whole blood. And I agree on giving whole blood can put a big stress to our body, but not so much with the plasma/platelets because the replace the same amount of fluid we give. Depending on our blood types, some are more suitable to giving the whole blood (O type), some for plasma (AB, A and B) and some for platelets (A and B). I'm on the plasma and platelets category, so I get to check the Hb level every 2 weeks. One of of the benefit visiting Redcross regularly. :)

Is hematocrit a proxy for measuring haemoglobin? You did a good job of explaining the science behind how over-training degrades performance. Dylan Johnson will be jealous!

[@nerocoaching]

Yes for most people, in most scenarios, testing Hb or Hct will have the same outcome

[@rodgrierson9621]

Is there any credible research on increasing hemoglobin through breath work?

[@Timo-qb1gf]

Doesn't everyone do that even if not knowingly. The base phase / Z2 training impact largely is considered complete when your HR has dropped and stabilised on a given effort which usually takes 6-8 weeks. That's mainly the plasma volume component as your study said. And when losing fitness you loose the excess plasma volume when not training.

[@nerocoaching]

Increases in hemoglobin mass can occur for months and months, not something that is maximised in 6-8 weeks. I think many riders who hit plateaus in training after 3,4,5 months are doing so because they've hit a limit in how much their hemoglobin can increase, because they aren't optimising the things discussed in the video. There may be many other reasons for plateauing, this one I think is not discussed very often. Also the idea that once you reduce your HR drift your foundation is built and only then should you increase the intensity of training doesn't really make sense. And even if it did, HR will always drift when exercising, even at low intensity, there's no way to quantify what is a "good" amount of drift, and the drift can be impacted by many things like acute fatigue which are unrelated to fitness increases so that becomes a wild goose chase

[@suadmahmutovic6542]

So hance you should always be working on Zone 2 which really is not just base but huge recovery method especially lower end Zone 2 is my understanding. Getting out of the middle so we can go hard when need to and not always be under recovering.

[@jenorite80]

Yes you are correct Timo, blood volume is quite responsive to training and not training. This is why it feels so tough the first few rides after time off the bike. And yes HR drift is a good practical measure, all other things equal, for the internal physiological response to external effort. Though there's plenty of benefits gained from Z2 aerobic stimulus beyond reducing HR drift for given power. Which I'm sure you still do beyond the base period. As any decent coach with a sports science degree will tell you and also help with increases to blood volume and haemoglobin mass/haematocrit to support high oxidative capacity if that is relevant to your race/event goals. As of course very important for a road racer, or pursuit rider like in this video, but not so much for ultra rider as they aren't going to max out oxygen consumption!

I'll mention one more interesting thing that sort of brings peripheral and central together...most cyclists, in a TTE trial at ~75% VO2max, will reach exhaustion when cerebral oxygenation has decreased by about 5%. That's some good info you won't find in the literature. There's no easy/safe way to increase cerebral O2 in isolation but my bet is if you could time to exhaustion would increase materially.

[@gongalab]

the point is that MTB riders have higher hemoglobing levels generally becaouse we train most of time at high intesity where Hr IS ALLWAYS IN ZONE 4,5,6 OR RATHER SAY WE RECOVER IN hR zone 4 . The point is we do produce less power in terms of force x cadence but we have lower pedal force but higher cadences due to terrain changes and interestingly we out run road cyclist at most of climbs becaouse their cardio system is not well adapted to severe tempo changes and constant sprints their cardion just can t cope and they have less effective lactate buffer so thats what makes us faster at most of terrains. There is no secrecy to it its just MTB is high intensity training in general and roaD CYCLING SEEMS TO BE MORE LONG HOURS STEADY STATE trainings to kind of get more muscular adaptation but hey what wins the race is being good at zone 5,6,7 . So im surrprised you mentioned this in 2023 what is well known since decades ago. As well hill runners are very good in MTB and road climbing races despite they never trained each of disciplines but rather theeir nature of training is as well high intesity where Hr is constant at zone 4,5,6 they rarely see Hr at level zone 2 or 3 unless they walk on straight or recovery run. From my personal experiances and training 3 months prior to race my Hemoglobin was raised till 183 and Hematocrit 54- and believe it or not i was warned i might be suspended becaouse my number of hematocrit was out of 49.99 limit for UCI. But i can say the feel on up hill with this values seems like riding a flat road not uphill due to insaneVo2 max-power increase. :) at age 40.But trainings include much ov high velocity -cadence and high force on pedals but short bursts which are repeated at very short recovery periods. And body response as it does.

Did you miss the 90s and the 00s? It was all about what they could do with their blood to improve performance back then. 😆😆😆😆

[@durianriders]

Still the same today bro. The times are even faster. Just look at marathon, 5k etc. The drugs are way better and we understand how to pass the tests better, pharmacokinetics etc.

Only person I watch that even talks about blood is durianrider. He talks a lot about vegan because it's gonna help you a lot when there's minimal fat flowing and blocking your blood. He talks about about hydration so that you have better blood volume. And he talks about sugar so that it can flow into your muscles so you can perform better. I think fitness is all about in the blood. And also when talking about recovery, you missed sleep, sleep is very important because not getting enough sleep and sleeping late at night effect our hormones as well.

I agree Durianrider is one of the few people I've seen that bring it up regularly

@@nerocoaching There is another KZbinr called Ash Beech who used to be very active but stopped. He did loads of videos on it too. Anyway, DR and Veganism have their haters but you can't say it's not optimal for blood quality!

@@philadams9254 why aren't most pro riders vegans then? Red meat is the absolute best source of iron. Vegan alternative iron suplemets are hard to digest and not much of it gets absorbed.

[@nerocoaching]

You can perform well on a vegan diet (I have), but I wouldn’t say it’s preferred for blood health over any other healthy omnivorous diet. There’s nothing special about it, if anything it makes it harder because you’ve got less foods to choose from to hit your nutritional targets

Its amazing to me how many people spend so much on bikes and gear and ride all the time. Then they don't even take a multivitamin. Frickin crazy.

"Riders will dope... to increase their hemoglobin... It's worth sorta sayin" :)

[@HarryTzianakisTheGodOfSpeed]

To increase hemoglobin jogging is good. People who hate the jog the best way for cyclists to improve hemoglobin is heat training.

[@HarryTzianakisTheGodOfSpeed]

For cyclists elite cyclists heat training is how they increase hemoglobin. Can altitude do it? Yes it can. But heat training is more effective when it comes to the density Altitude training teaches your body to use less oxygen, therefore the restriction of the oxygen is what pushes hemoglobin increase. But a more effective way is heat training

[@savagepro9060]

@@HarryTzianakisTheGodOfSpeed Indeed, Ijust googled the notion that jogging increases hemoglobin. But, by that token of physiological reasoning, shouldn't triathletes be the fittest freaks on Earth? 'Jus askin, DUDE!

[@HarryTzianakisTheGodOfSpeed]

They are!

[@DeTaPix]

Another way to increase blood volume and in turn red blood cell count is to take cold showers. They are proven to stimulate capillary growth which then demands more blood to be present in the system.

[@douglasbooth6836]

I have 58% red blood cells. We don’t know why. I get a half litre taken from me every month. When coming to my yearly etspe I don’t give blood.😂 This why the professionals train and live at altitude. Add blood doping you are miles higher than anyone else.

[@douglasbooth6836]

@@nerocoaching the problem is your legs are always behind your cardio. At my age anyway. It’s why riders need time to get race fit after being at altitude. Can you imagine how the guys felt after getting an extra 1/2 litre added to themselves before a race back in the 90s. They must have felt like superman.

[@HarryTzianakisTheGodOfSpeed]

Go look at my Strava today I was flushing out. The jogging soreness. My cadence was at 130 + for minutes at a time. That's how you keep your hemoglobin and recover at the same time. I'm not your enemy. Jesse, I just know better than you
