Athletes have more mitochondria’s and more efficient ones?

No they burn more energy and require faster repletion for high-intensity activities.

And they burn more energy cause they have more mitochondria in their cells due to training

Low intensity builds more mitochondria per cell and high intensity trains them to work better

For strength training more muscle mass means more mitochondria to burn fat

“Low intensity” he’s specifically referring to zone two cardio, which every type of athlete has to do a lot of to maximize performance

Just look up “aerobic exercise and mitochondria” https://www.trainingpeaks.com/blog/zone-2-training-for-endurance-athletes/

I just picked one of the first ones there but yeah, google scholar will take you to better ones if you add stuff like meta-analysis or review to it

Idk if what they said about high intensity was true though
