I dont think there are such things as oxygen cells. However, there are red blood cells (erythrocytes) that have hemoglobin, a molecule that oxygen can bind to. Throughout literally every cell in your body, there are capillaries. These capillaries deliver red blood cells to all of your cells, including your muscle cells.
The Circulatory System. Blood carries these throughout the body.
In order for the muscle fatigue to end the muscle cells must be provided with oxygen to 'burn' the lactic acid.
During exercise muscle cells use oxygen.
All cells need Oxygen.
If the demand for oxygen is not met for a long period of time, the cells within the muscle tissue will die.
The circulatory system, specifically the cardiovascular system, is responsible for delivering nutrients to cells throughout the body. This system uses blood vessels, such as arteries and capillaries, to transport oxygen and nutrients to cells and remove waste products.
The iron-containing protein in muscle cells that controls oxygen uptake from red blood cells is called myoglobin. Myoglobin helps muscles store and release oxygen as needed during muscle contraction.

The process in muscles which uses oxygen is called respiration. Muscles, like all aerobic living cells, require oxygen for aerobic respiration, which is the process by which cells convert food into energy. So when muscles contract, they are using oxygen. When muscles do not get sufficient oxygen for contraction, problems arise. The muscle cells must use anaerobic repiration which is respiration without oxygen. They cannot do this for very long though as the byproduct of anaerobic respiration is lactic acid which causes a fall in pH.
During vigorous activity, muscle cells require more oxygen to produce energy through aerobic metabolism. However, the rate of oxygen consumption may exceed the rate at which oxygen is delivered to the muscle cells, leading to a low oxygen concentration. This can result in the switch to anaerobic metabolism, producing lactic acid and leading to muscle fatigue.
