Anaerobic respiration (without oxygen) would caused muscle cells to produce lactic acid. This causes the muscles to ache and in the long term, damages them. Also anaerobic respiration releases far less energy (ATP) than aerobic respiration. So it is best for muscle cells to respire aerobically as they need more energy.
