Lactic acid system

A-level PE

What a video! Extremely easy to understand and very useful!

Hi James, I just wanted to thank you for such a clear video on this system. I am a personal trainer who specialises in plyometrics and this energy system is used in every session I create. By getting my clients to understand what's happening inside their bodies I have seen them able to raise their pain thresholds and work with the acidic environment for longer. You're a gifted teacher.

Love your videos and find them really helpful. However, lactate does not cause muscle fatigue and pain, it is the extra protons in the body (usually hydrogen ions) that makes the pH balance more acidic causing that burning feeling. Known as muscle acidosis. In fact, because the lactate lacks a proton, it actually takes on some of those extra protons to try and reduce that acidity in the muscles. Lactate is just trying to help. Famous quote, correlational does not equal causational. Meaning just because two things happen at the same time, it does not mean that one causes the other.

really helped me with my GCSE PE work, thanks

You mentioned lactic acid causes pain, soreness and fatigue. What about the hydrogen ions, isn't that the cause of reduced performance?

[rolabode]

I'm so grateful for this thanks a lot!!!

Wow. I'm loving these videos!Thank you so much!

Brill video!, but he needs better handwriting, but 10 out of 10 for explaining.👍👍

Hi, How can i be at maximal intensity using this system if it "don't produce a lot of energy" ? 🤔
Thanks for the video 👌👌

[carlinconnell]

Im pretty sure pain and soreness does not come from lactate

Hi James Thankyou so much for your videos they have been really helpful with lockdown and everything going on at the moment, been really useful for helping me complete my assignments.

didn't know tyson fury was a chem teacher too

It's not the acid that causes this. It's the build of H+ ions that cause the pH balance to occur and cause fatigue.

Hi Izabella, no problem. Essentially lactic acid and lactate are the same thing. Same applies to Pyruvic acid and Pyruvate. It's just different terminology for the same substance. Hope that helps.

[joellesassine]

All is great, instead of the maximal intensity thing it is not very accurate sometimes you use the lactic acid energy system when you use intermediate intensity

[markjones]

I would propose that another advantage of using this system is the ability to redline the anaerobic/lactate threshold, thereby creating the possibility of hyperplasia. It's not easy, of course, and your ability to endure the pain thereof for an extended period of time would be the main limiting factor(assuming proper rest, nutrition, etc. are established). The only way to do this is with dropsets, otherwise you are risking injury by putting to much stress on the joints and connective tissues. Would you concur with that assessment?

It’s all very well to give an over view but generally people already know this they want to know more about the actual system and not abbreviate ie ATP etc etc best say Adrenalin Tri Phosphate which is what it is...!! Please be accurate and accountable...
