VO2 Max and Lactate Testing with Marathoner Reed Fischer

[@ParLy11]

Reed studied for this test and it showed

[@jhiaaa]

this guy explained to me threshold lactace and VO2max in 30 secs, great teacher

[@thomasphilyaw8593]

Love the science of running and how it can pinpoint what you need to do to get better. As they say science doesn't lie. Let's go Reed!!!

[@mikestevenson1334]

I love the videos with Reed. Such a beast - VO2 Max over 80 :O DAMN! Great job, Reed!

[@justjustjoo]

12:14 Him allowing the runner to walk around or sit by preference is a mistake, when taking the recovery lactates. You see, lactate is being eliminated much quicker from the blood if you're doing very easy running and walking. You can't compare these numbers for the next test. Instead, the recovery speed should be the same every test.

A 2:10 marathon PB is so absurd lol. Big Reed Fischer fan here.

[@jordans1712]

That was an amazing effort! So hard to do that with the gear on. And Reed has the best personality

[@rinotz7]

How can you not love Reed?

[@certifiedgoofball.]

FYI the exercise physiologist Ka’eo is one of the best American triathletes and a 3:40 1500 meter runner

[@BollywoodMediaOnline]

4:02 omg it is crazy how marathon runner's easy pace is 6:26 🤯

[@dr.mohamedaitnouh4501]

You can train for it ... his VO2 mas is 80

[@chessplayer-ms3pn]

@@dr.mohamedaitnouh4501 you canttrain to that point unless you have exceptional talent or start very young

[@jimblack8104]

Amazing video. Thank you!

A 1.3 mmol lactate threshold is absurd. Makes sense he's a marathoner, they typically have very low lactate levels. Still, I think the usual is like 2.5-3

[@2MuchNoiseRs]

He would need to improve his Vlamax (anaerobic capacity) with short sprint intervals so that he makes more lactate at lower level of intensity. Since his lactate clearance ability is so high yet (seen in his extremely low lactate values at LT1/LT2), he will be able to use the extra lactate from an increased Vlamax for extra 'fuel' for his aerobic energy system. Base line, his VO2max (aerobic capacity) is now too high versus his anaerobic capacity. Which is good for the marathon racing day, but not in preparation. You want to bring Vlamax up first and then bring it down again in the specific training block in the weeks before the marathon.

[@Haitham___ww]

interesting! I never feel a lactate burn during my workouts. I think my body is not producing much lactic or it's clearing it fast. Do you think I would also benefit from some anaerobic intervals?

[@2MuchNoiseRs]

@@Haitham___ww If you combine it with easy running yes. Simple intervals like 5x100m sprint with 2 to 3 minutes passive rest can increase your Vlamax. If you go for a 20-30 minute easy run afterwards, this will also boost your Vo2max.

[@Haitham___ww]

@@2MuchNoiseRs thank you! I will start doing that. I rarely have done any sprint intervals during my workouts! Only been doing 200/400m intervals but i suppose most of the power is still aerobic since i run them at mile pace

[@2MuchNoiseRs]

@@Haitham___ww That is indeed aerobic power intervals. Anaerobic capacity requires (almost) all-out intervals of 10 to 30 seconds with at least 2 to 3 minutes passive rest.

[@markbarbour6395]

Lactate is simply the first metabolite in the breakdown of glucose. Actually, pyruvate is the first metabolite, and it is further broken down in the Krebs Cycle if oxygen is available for cellular respiration. Lactate is only produced in the absence of sufficient oxygen when the pyruvate is converted to lactic acid during anaerobic cellular respiration (lactate fermentation). The energy gain from that step is 2 ATP per glucose, whereas the energy gain from breaking down the pyruvate with oxygen is 30-36 ATP per glucose. Looking at lactate as "extra fuel" because you can get 1/15th of the amount of ATP by creating it as opposed to fully metabolizing the glucose down to water and CO2 seems penny wise but dollar foolish. I don't see how lowering his lactate threshold (resulting in raising his anaerobic capacity) during training and then raising it again (resulting in the lowering of his anaerobic capacity) immediately before a marathon will benefit him on race day. Can you please expound on your logic?

[@fivesolae5894]

This video is great! Thank you. A lot of fun getting to ride along with the experience. It’s very interesting to watch Reed progress through the paces. I’ve always struggled to understand the ‘feel’ of perceived effort. Video idea suggestion…what does Reed feel he has to change as he moves through different phases or perceived efforts to know “this just moved from a 5 to a 7”. Congrats on Chicago for Reed!

[@DanielFine-c5r]

Great video! Would you mind explaining the reasoning for performing intervals for the VO2max test instead of steady state? Do you think that can influence mmol Bla ?

[@Trailcat2024]

Great stuff!!!

[@gregorykarimian3813]

Reed: Just relaxing coach. Coach: I should hope so with that pace. Ahhh cmon, why did you have to do me like that haha

[@ListlessSpectre]

You da man, Reed! 👍

[@8gomerpyle22]

How long before the pharmaceutical companies offer a continuous lactate monitor for sale? As for me, I’m lactate intolerant.

[@thetrackclubcoaching]

Love to see it

[@lukepaulson3428]

Awesome!

[@owenwhite748]

So if a person's "gas tank" is full, is there any way to get a bigger gas tank? Or is it really just the one your parents gave you?

[@bcty11]

You can improve everything

[@devakasw]

Both VO2max and VO2max trainability are influenced by genetics (interestingly almost 2 different sets of genes), however you can improve it with (not only!) VO2max intervals. But VO2max is 'capped' by genetics. Unless you were born with 'extraordinary' genetics you probably cannot reach 80ml/kg/min.

[@tommywadelton6305]

The edit at 6:41 😂 Enormous p....

[@gcp21]

what’s the wheel used for behind the tread?

[@sandrocrocelli1709]

To check the speed, I suppose

[@Zoominguy007]

What phase of his training is he getting this testing done?

[@AZ-hm2or]

Why not be checking lactate on his threshold runs. Seems like could have easily known he wasn’t spending enough time just under lt2.

[@xctryhard4736]

6:40😂

[@gcklo]

The lactate meter is probably broken

typical science says you are doing good and bad at the same time jajajajajaja
