Muscle
When your muscles use energy to power muscle contraction 3 quarters turns into heat.
Doubtful. One would think that any glycogen stored in muscle cells would be producing mitochondrial ATP for use in the sarcomere, the muscle contraction unit.
It helps runners store extra energy for later use for muscle contraction and movement
The levator palpebrae muscle is primarily responsible for opening the eyelids, it is innervated by cranial nerve 3 (occulomotor nerve). Raising the eyebrows, which will also open the eyes wider and may be what you are asking about, is done by occipitofrontalis. This muscle is innervated by cranial nerve 7 (facial nerve).
Muscle
Isotonic contraction results in shortening of the muscle, leading to movement. In Isometric contraction, as the name implies, there is no change in length of the muscle. Thus, it can't lead to any movement. However, Isometric contraction adds or removes power from a movement, thus facilitating or retarding it. This, facilitation and retardation itself gives us a feeling of movement, for example walking, even in the total absence of actual movement i.e. walking. This feeling of movement induced by isometric contraction is known as Isometric movement. We use isometric movements in thinking and dreaming.
The state of partial skeletal muscle contraction is known as tonus. Muscles of the body do not have a real state of total relaxation.
The brain stem controls muscle movements. Even involuntary movements are controlled by the tiny brain stem. Without the use of your brain stem, you will not "remember" how to do the simplest task.

Diffusion of cytoplasmic oxygen.
The function of the Orbicularis Oculi is that it closes the eyelids.
Energy to muscles is supplied through mitochondria making ATP using oxygen. Muscle cells use a tremendous amount of energy so they have large numbers of mitochondria.

It depends a lot on what position you play. But just about every muscle is used. everyone will be using their legs, so quads, hamstring, calfs. Anyone who blocks will use triceps and shoulders a lot.
It's is the contraction for it is....so if you are using the contraction, use the apostrophe. If you are not, then do NOT use it.
