Are Body Muscle Forces Conservative?

[revolutionx89]

Homework Statement

Our body muscles exert forces when we lift, push, run, jump, and so forth. Are these forces conservative?

It's a yes or no question.

Homework Equations

Not really sure what to put here, as it's not an equation kind of problem.

The Attempt at a Solution

I'm pretty sure they're not conservative, as I can't think of any potential I'd be able to associate with a force I apply, nor can I imagine them as a field. I only have one submission (it's an online homework), so I'd just like some confirmation on that.
Thank you so much!

Well, how do you define a conservative vs. non-conservative force? If I lift a ball off the ground, surely chemical energy has been transferred to the ball to give it a potential energy, but does that tell the whole story?
