Your muscle cell break down energy from food turning it into the process of respiration.
Respiration is when the body turn carbon dioxide into oxygen
Edit-
Oxygen is used to create ATP in the muscle cell site, however it is still possible to create ATP without oxygen. this is called Anaerobic glycolysis and is when energy from glucose (sugar) is broken down without the presence of oxygen. the byproduct of this reaction is lactic acid and causes the muscles to retard and tighten up.
The muscles continue to get enough energy during high levels of activity when there is not enough oxygen through the absorption of water. It is a good idea to drink water frequently when doing strenuous exercise.

Fermentation
Glucose
I think it's because of a process called fermentation
Yes. Fat is a good energy source for muscles during almost any exercise. It's easily converted into energy.
Kinetic energy is produced. The energy your muscles use is chemical energy, which is gotten by food. The muscles do an action, therefore giving off kinetic energy.

during a (n) activity
by eating good food and rest.
Muscles turn chemical energy into heat and work during contraction. Straight from the science book.
When you exercise you use your muscles and your muscles contain Glycogen which could be considered your "energy source". during exercise your muscles use glycogen depleting your energy levels making you feel tired.
protein....muscles.
