Hi Mike, These videos have been absolutely fantastic! I was given lectures at university which have been very confusing however you explain everything brilliantly! Thanks so much
That's really encouraging to hear, Joseph. I very much appreciate the positive feedback, and of course you're very welcome. Hope your Uni studies are going well in spite of all the crazy circumstances this year.
Hi thank you for the video. finally a way i can understand this. I have a question. If the lactate system can only last 2 mins how do people do fasted cardio? does the lactate system carry on or does it literally only last 2 mins?
I think he meant one GLUCOSE molecule gives 3 ATP, not a glycogen (at 6:09) molecule, as the latter is a much biger polymer of a glucose 'beads", and has a variable size.
Recovery 1-2 hours from which point? If you do multiple sets or sprint in a football match that obviously use the lactate system what does it mean in that context...? Thanks
Hi Zebra. Thanks for the question. In a football match (or after multiple sprints) the lactate system is able to *partially* recover while the body's aerobic system is dominant, and this allows repeated anaerobic bursts of exercise (take a look at this video for my explainer of how the systems all work together: th-cam.com/video/aYzxC5Gy8SQ/w-d-xo.html). However, if we did a lab test in which we get someone to do 30-120 seconds of 'all out' exercise then after exercise it would take 60 minutes or longer for blood lactate to return to pre-exercise levels. Take a look at Figure 6 from this paper for clarification: www.ncbi.nlm.nih.gov/pmc/articles/PMC2769631/ So the figure of 1-2 hours means the time taken to return blood lactate levels to resting levels after 'all out' exercise that depletes (or nearly depletes) the system. Hope that helps.
Mike Tyler Yes thank you very much... and thanks for all the great videos👌. By the way, not that it matters so much (I just need info for general knowledge - not studies...😜) but I always thought the glycolysis produced two atps per glucose molecule... you mention it produces three? Is it more an approximation or is it dependent in it being aerobic vs anaerobic...? 🙏🏼
Thanks for the video Mike - I'm just a little confused by the recovery time of 1-2 hours? The literature that I have read around this topic, as I am about to teach this, all state approx. 8 minutes...? I did think that 1-2 hours sounded like a long time for recovery of a bout of exercise lasting less than 3 minutes?
Great question. The 1 to 2 hours figure is the amount of time needed to complete the slow recovery stage in excess post-exercise oxygen consumption. That is, how long it takes to clear *all excess* lactate after a prolonged bout of exercise over the lactate threshold. I'm not sure where the 8 minutes figure comes from but this paper (www.ncbi.nlm.nih.gov/pmc/articles/PMC2769631/) says that an 'all out' effort up to 3 minutes may elevate blood lactate to a peak that can last up to 8 minutes post exercise. Hope that helps!
Very interesting. May I ask what your source of this system is? So hard to find good sources! And does this mean that what brings lactate to a level that will be difficult for the liver to break down (and lead to high lactate levels in the blood) can come from not enough glucose? and not from lacking oxygen, at the anaerobe threshold, as often depicted in other explainations of this?
I like so much the quantifications; timing at which energy system kicks, magnitude of acidity couming out of the chimney.
Wow you have great teaching skills.thanks sir.
Very informative ❤
Got an exam on monday and these videos are a really helping with my revision. Thanks keep them up
You're very welcome. More to follow...
The manuals are doing my head in. I appreciate being able to watch these video tutorials instead.
Thanks. Glad you find them useful.
Thank you for the azaming breakdown. Thanks to your energy system series, the whole chapter seems so simple now

very helpful and clear video. Thank you!
Glad it was helpful!

Lactate system will stop working after 2 minutes where Aerobic system will take over the rest of the workout.
It has really helped me, I have an exam tomorrow
Glad to be able to help. All the best for your exam.

Indeed I do! Well spotted, and thanks for commenting.
