Or are they the same thing? Does your heart use both during the metabolic process? Or! If lactic acid is what you feel in the muscle due to lactate build up? How does this help with endurance during short and long high intensity workouts?
Thanks in advance

Are you sure you don’t mean lac*tose*? *Lactate* means to produce milk, such as a mother mammal producing milk for her offspring.
In physiology they are the same thing. Lactic acid becomes lactate ion in solution by losing one proton.
In the body, lactic acid is produced during anaerobic cellular respiration, when it enters solution it is lactate. Muscle tissue uses up glucose to produce pyruvate which in turn is used to power the cells, and in the absence of enough oxygen, the byproduct is lactate. It is ten times more acidic than acetic acid (the acid compound in vinegar). Lactate can be metabolized back to pyruvate when oxygen is present and then used again for energy production.
I can’t really eli5 it any better.
Same thing, pretty much.
When your muscles have hit their limit in the amount of power they can generate aerobically – with oxygen – they can generate more energy but that results in the accumulation of lactate.
To keep the reaction going, the lactate is shipped out to the bloodstream so that other tissues that have enough oxygen can burn the lactate. As power increases, eventually the athlete hits their limit in processing lactate, and that’s the lactate threshold.
So generating more power in that range is mostly about improving lactate clearance – the ability to get lactate out of the muscles and processed by the body. That’s what high intensity training does.
