Oxygen Deficit and Excess Post Exercise Oxygen Consumption EPOC - VO2 Kinetics

This video shows Dr. Evan Matthews explaining oxygen deficit and excess post-exercise oxygen consumption (EPOC). These concepts are important for understanding the VO2 kinetics (oxygen consumption kinetics) when we transition from rest to cardiorespiratory exercise and back to rest and recovery. This video is part of a series of videos that will cover exercise metabolism. The playlist to that series is listed below.

These videos are unbelievable. Extremely clear visuals and delivery. Very helpful in my Nutrition classes. I'm also very impressed in your effort to respond to all the comments. Keep up the great work!

At what point will AE Threshold happens & at which point AN threshold by increasing intensity of exercise & oxygen deficit?

[weizhanghao]

Thank you for the wonderful explanation, really helped me understand the graph

[surtal]

thoroughly explained and thoroughly understood sir,
regards from India 🙏

[JoyBoy_]

Amazing explanation.. thank you for making this helpful video!

[bevinreynolds]

I’d be so curious to know how this would change for a sport such as freediving where the whole performance is done on a single breath.

[tonyrabone]

Thank you this is very interesting. Lactate to glucose - would that be through the cori cycle?

[Hghugf]

Do you mean Anaerobic energy is always produced first until aerobic energy is able to take over? (In low intensity exercise)

[Ordinary-Hendrik]

Thanks for the presentation! Can I conclude that the higher the Vo2max will cause lower epoc? Thanks !

[LM-rrns]

Where does the excess oxygen come from in EPOC? Metabolic processes? The term oxygen "consumption" has always confused me - I understand that the body needs more oxygen to return to homeostasis but WHERE does the oxygen needed for recovery after high intensity exercise come from? People certainly don't continue to breathe heavily after exercise. Thanks in advance.

how scientists know the pink area is oxygen deficit. & why the corner of the pink, stop at one point. is there any calculation . I am not good in maths. I'm a biology teacher. thanks a lot.

[dieglhix]

I fail to explain why HIIT & Tabaca is so good compared to normal cardio because EPOC is too complicated for me to explain, in fact I don't even know how it works, so I will study this video, thanks !!!

[omarmadkor]

Thanks alot. Can you add translation into arabic in the video, please?
