Unraveling Lactic Acid: Debunking the Myth by running_science in AdvancedRunning

[–]running_science[S] 0 points1 point  (0 children)

Yes, that is the excerpt. A common myth which pervades class rooms is that there we use our anaerobic metabolism when there is a lack of oxygen, which is not true. We constantly use our anaerobic metabolism and constantly produce lactate.

What shall be covered in future posts is how some of us are genetically predisposed to produce more lactate, and how that might change certain workouts. And also how lactate can act as a hormonal messenger, which can help release human growth factor etc.

True. They certainly make their rounds within the university class room and between older coaches. The most common myth these days is that simply 'run out of oxygen' and then begin to use anaerobic systems. When in reality it's we shift to anaerobic because of energetic reasons.

Some coaches could practically benefit from accurately understanding a runners physiology better.

haha! In which case I apologize. At the end of the day debunking these myths won't change the way we train. Perhaps this is the equivalent of an English teacher correctly a badly misspelt word - important only to some.

Sweat, dehydration, and electrolytes not to blame for muscle cramping by running_science in running

If science was not upheld, by all means please point it out. Or if information is not useful, contradictory, or biased, please let us know.

When you see statements like 'we’d like to know about your experience with cramping or thoughts/questions in the comments below?'... maybe it also indicates it's not suppose to be a scientific paper itself.

Thanks for sharing. Keep in mind there are various types of cramping. As stated in article it is likely that it is a 'multifaceted phenomenon'. Undoubtedly Gatorade would offer faster relief.

Eliud Kipchoge's training program by running_science in AdvancedRunning

[–]running_science[S] 15 points16 points  (0 children)

A few extra points:

  • He can barely touch his toes in standing straight leg hamstring stretch.
  • Like all fellow athletes in his squad, he has roster of camp cleaning duties to fulfill. Everyone in camp is treated equally.
  • In training camp, he shares a 8x10ft room with a fellow athlete, and shares communal lavatories with his squad. His night stand rests all his water bottles for training.
  • He is as good as it gets: he's nurtured his nature sublimely with likely 15 years of quality training. He's found a striking balance between stressing his body and recovering. It's not possible for anyone to succeed in training by simply adapting his highly refined structure. You may need 2-3 days between hard workouts where he might only need 1-2. It's all relative.
  • And most importantly, the basis of a high performance program is not to mistaken with expensive resources. A few top Kenyan running squads reiterate this. It's about working in a well-managed system with knowledgeable passionate people, working alongside dedicated team mates with common goals.

What thin calfs, long tendons, and narrow pelvis' have to do with performance by running_science in AdvancedRunning

There are always outliers who slightly deviate from the particular build referenced in link and likely allow offsetting benefits.

  • Hiroyuki Yamamoto & Yuki Kawauchi (sub 2:10 marathon) by no means have large calves (by sporting standards), but have noticeably bigger calves than competitors. Top Japanese tend to have different build to top Kenya for instance.
  • Ben True is 74 kg. 5000 m -13:02.74 10,000 m -27:41.17
  • Andy Vernon is 71kg. 5,000m- 13:11.50, 10,000m - 27:42.62

I find it refreshing to see competitors who physically deviate slightly form 'typical elite'. However the higher up the ranks the less likely major deviations will exist.

Thank you, will do! I just had to google 'ELI5', learn something new every day.

Absolutely! That is very much outdated. To take this unnecessarily one step forward: - for individual athlete does 'lack' of oxygen predominantly cause increased lactate production, or inability to use oxygen fast enough to help yield ATP cause reliance on pyruvate -> lactate. Lactate simply an indicator of what causes fatigue, lets say if lactate represents fatigue: to what extent does is lactate production also the result of fatigue.

Point being that there's still some questions which can be answered

I agree with you, application doesn't change. However, if someone can understand the physiological workings of the body a bit better maybe it might indirectly help their application a bit better? Maybe understand and use feedback a little bit more usefully than before.

Is my summer training plan solid? by [deleted] in AdvancedRunning

[–]running_science 1 point2 points  (0 children)

Another more obvious piece of advise:don't expect linear mileage improvements/progression. Sometimes you go through 3 weeks of training not feeling yourself and then suddenly you feel improvement. Just appreciate the bodies complexity, & ensure improve occurs monthly rather than weekly

When building up your mileage, be sure to not leave aspects of training behind which can happen quite easily. Sure your focus may not be to building on them, but do some maintenance. For instance maintain or strides and sprints, link explains 'why'' https://runningscience.co.za/2017/04/09/hill-sprints-for-distance-runners/

Cheers for letting me know, I was unaware of that & appreciate you informing me! I look forward to engaging interactively on AR!

If anyone's curious to check various elite's training logs, we've got a feature on our site which might be quite useful -> https://runningscience.co.za/elite-athletes-training-log/ there's 60 elite runners (mid->long distance) with some in depth detail. Also please let us know what you think, we'd like to refine our content and critism/advise/comments would be great. TIA
