I was helping my neighbor move some boxes around and the stuff was pretty heafty. So we finished and one thought led onto another and then I ended up here.

I mean one perticular muscle at 100%, not all the muscles in our bodies.

No, humans do not use 100% of a muscle all the time.
For instnace, while we are asleep, only a few muscles function and they do not function to their fullest capacity.
Therefore, depending on the action that is being performed, then that is how one can determine what porcentage of their muscle is being used.
Chickens hardly use the muscles on their wings because they hardly ever fly, instead they use the muscles on their legs on most ocassions.
Geese on the other hand use more of the muscles on their wings because they fly super long distances but as for the ones on their legs, they are a bit weaker because they do not use these all the time.
As I am typing this message, I am using the triceps and the biceps within my arms, but because I am only moving my hands and fingers, then I am not using these two muscles to their fullest capacity.
Therefore no, humans do not use 100% of a muscle's capacity all the time.

No. I think you were asking if all of the muscle group gets used, like biceps or triceps. For every direction a joint can move, there are muscles to pull it that way. So there are always some muscles just sitting there waiting to go to work. that's why you can 'find muscles you didn't know you had' when you get sore from some activity that used them a lot more than they were accustomed to.

If you mean 100% of your muscle when using your muscle, yes, it all works as one.
If you mean that we use all the muscles made in our body - lets say you're lifting a weight with your hand - no. You're not going to work every muscle at the same time (working out just 5 minutes a day would make everyone look amazing!) because your muscles relax and flex to make your body work.

No you don't use 100% of your muscles all of the time. More practically you can't use a 100% of a muscle. Your muscles are made up of muscle fibers. Depending on the load that you are working with, a certain number of muscle fibers are going to be activated in order to perform that activity.

Even if you are using a single muscle like say Biceps , groups of muscle fibers of the same muscle work in rotation. Isometric and Anaerobic exercise require whole muscle work and that`s why such exercises are not advised.

No, I don't think so. I am not a doctor.
