Sir, I honestly tried for a long time to understand this concept and the difference between the different pathways. You explained it simply and very intelligibly.

[@mikefitfreak5323]

I have an essay for issa and this info has helped me alot

[@TheMovementSystem]

Great!

[@vigneshr2685]

Thnx for this videos

[@TheMovementSystem]

Thanks for watching Vignesh!

[@mohamedaboelfotoh7692]

What if I haven't eaten carb for a long time, and i am going to do a long endurance exercise?

[@TheMovementSystem]

You likely won’t be able to train as hard due to less glycogen storage and ability to generate ATP from carbohydrate

[@lopez316a]

Joel jamieson talks about it being a myth that the body starts at the anaerobic end and then works its way ‘down’ based on its conditioning levels. He states that it’s people’s cardio conditioning that dictates the speed at which the body goes ‘up’ the energy systems. Thoughts ?

[@DanielELnabbout]

Exercise physiology is gonna be a vibe this semester with these videos thanks man

[@TheMovementSystem]

Way to get a head start

[@whithill7353]

So if we are primarily using carbohydrates for energy up to about 3-4 hours of exercise, how does fat get burnt? In other words, what energy system is responsible for fat burning/losing excess weight? Thanks for all your videos, Matt. You helped me get my CPT and you're currently helping me get my Nutrition Coach cert :)

[@TheMovementSystem]

There are quite a few systems involved. Triglycerides are first split with lipolysis then broken down further with beta oxidation. Then they become acetyl coA and enter the Krebs cycle.

[@soccerisdabest5371]

Is oxidative phosphorylation another name for the ETP? Electron Transport Chain

[@TheMovementSystem]

Yes

[@Jone_BoneJones.]

Please add chapters in the videos

[@brunospasta]

If I do a low intensity ride for 2h and then do a 10 second sprint vs doing a 10 second sprint right at the start, I can push about the same Watts. So I assume its not only the length, but also the intensity of the excercise that determines which system is used? Also I assume that the ATP-PC system can "recover". Otherwise I could only sprint once per training. Are these assumptions correct?

[@TheMovementSystem]

Yes exactly. Aerobic work doesn’t deplete the ATP Pc system

[@theiriscen]

Thanks for this. Other videos dont actually make the distinction between fast and slow glycolysis and how the long term aerobic pathway instead used fats to make energy.

[@joshthomas_1696]

Thanks Matt! I graduated with an exercise science degree just like you. This video took me back to those sports nutrition days haha. Great video 🙏🏽

[@mallasensei]

You’re doing a really good job brother :)

[@38kunalsharma85]

Love this chapter wise distribution, hope you can continue this. Much love❤️

[@tazzmanncharles]

I have the understanding of the energy systems. But my question is lets say John Doe is 300lbs do we mix oxidation with fast glycolysis? Am also thinking about thermoenergetic

[@TheMovementSystem]

There's always some mixture of energy system usage. So fast glycolysis and oxidative systems will both contribute to some extent maybe 50/50, maybe 60/40, maybe 70/30. Thermic effect of food is kind of a different topic

[@GunnedDownAtrocity]

so how is slow glycolysis and oxidation of carbohydrates being distinguished in this chart? is slow glocylysis up to and including the krebs for 2 atp and oxidation of carbs the oxidative phosphorylation step that gets another 34 atp? am i missing something?

[@Kinslayers0]

I’m confused with slow Glycolysis, fast one doesn’t use O2, then does the slow one use O2? If yes, would not that be Aerobic?

[@TheMovementSystem]

Neither use oxygen actually. Check out this video: kzbin.info/www/bejne/aZ_WZmiplNSfg9U

[@satyammishra9685]

I have a doubt. Let's say i go for marathon is it possible all the energy system work in my marathon i mean first phosphagen for 10-12 secs then anaerobic for 30-40 secs then aerobic energy system for rest of my remaining kilometers

[@TheMovementSystem]

Sort of. It's always a mixture. There's a primary and secondary energy system. So rather than one working then turning off it just goes from primary to secondary

[@mattdelgreco5827]

@@TheMovementSystem I'm having the same thought. My initial interpretation is that you will use the available ATP from PCr, then anaerobic because your body can produce it more quickly, then a transition to aerobic because you've depleted anerobic capabilities, but are working at a low enough intensity where you can clear the lactate and use it as energy. But now I'm thinking your body would prioritize the aerobic system and kind of "skip" the anaerobic system before eventually transitioning back to anaerobic if you hit your lactate threshold?

[@MereMortalsBookReviews]

Really enjoyed the way you put together this video mate, much appreciated

[@TheMovementSystem]

Thank you!

[@kOt985]

So in terms of diet, would you say a ketogenic diet would be more effective for losing body fat in conjunction with aerobic type training?

[@Afatp]

How can we employ energy currency during workouts?

[@anishjoshi2777]

Master I am doing climbing rope exercise, if I want to increase endurance on climbing rope doing up and down for many times, which training methods should I use in training to increase my endurance I m ectomorph by body type. Also any supplement u want me to take. Plz guide

[@fiolioco1523]

awesome thanks! this was very useful and succinct :))

[@anishjoshi2777]

Coz lot of lactic acid gets buid I want to increase threshold.

[@jacobfeldman1994]

May the fitness gods bless you brother!

[@TheMovementSystem]

Thank you

[@joaopires426]

Thank you! Great job explain each stage.

[@dipubolke7647]

Very well explained. Thanks a ton 🙏🏻

[@carlinconnell7715]

Hey, thanks for the video, can I get a citation

[@matthewmcloughlin7155]

saved me on a hpe exam Thanks dude

[@TheMovementSystem]

Nice

[@michelleb3198]

Hi Matt, thankyou so much for breaking this down. Great explanation of the different systems. I wanted to ask whether I could get this in text format?

[@michelleb3198]

It's all good, I found the transcript which is perfect!

[@ma1375]

Amazing channel

[@sawayp4031]

All vids are helpful
