PC I think this a great idea.

What if when your stamina bar is empty you can still sprint and do normal attacks, no heavy attacks, but the catch is that it directly taps into your thirst and hunger. Maybe, if you did it too much you could get fatigued. Maybe it would only normally kick in, in combat, but a perk could unlock it for use anytime. It could be like an adrenaline system.

So you could spam power attacks until depleted and then simply run away. Makes melee combat a lot easier.

I literaly just said: 'no heavy attacks'.

And I siad: 'Maybe, if you did it too much you could get fatigued.'

You could spam power attacks at a group of zombies until your stamina was empty and then still be able to use sprint to escape the situation.  I could see it possibly being added to the last point of Cardio but it feels like it would be too overpowered of a perk.  Needing to weigh out whether you should press the attack and use the rest of your stamina so you can't escape vs choosing to escape and rebuild stamina before continuing to attack is a necessary thing to have in my opinion.
