Adenosine Triphosphate (ATP)?
Glycolysis
When muscle cells undergo anaerobic respiration they become fatigued and painful due to the buildup of pyruvate in cells. The pyruvate is converted to lactic acid.
Anaerobic respiration takes place when you demand your muscles to do vigorous work. Normally, aerobic respiration takes place but when energy is needed immediately, anaerobic respiration takes place. During anaerobic respiration, the body produces lactic acid, which leads to the burning sensation. Your lungs deliver oxygen to the muscles much slower than the rate you need, since you're putting your muscles through an extensive exercise, and this leads to muscle fatigue.
combustion and cellular respiration
During high intensity exercises your cells become unable to perform aerobic respiration causing them to perform anaerobic respiration. This causes a build up of lactic acid in the muscles.

muscle cells produce ATP by cellular respiration through fermentation
During exercise your muscles need more energy from respiration in order to contract. So your heart beats faster and the arteries supplying the muscles dilate (widen)

Lactic Acid I know only one, there might be more.
The accessory muscles of respiration are the sternocleidomastoid, scalenes, serratus anterior, pectoralis major and minor, upper trapezius, latissimus dorsi, erector spinae (thoracic), iliocostalis lumborum, quadratus lumborum, serratus posterior superior and inferior, levatores costarum, transversus thoracis, and subclavius. The diaphragm is the main muscle of respiration (normal/relaxed breathing), assisted by the intercostals. No accessory muscles should be recruited during normal respiration unless there is a respiratory disorder. During quiet inspiration, the diaphragm and intercostals are activated. During quiet expiration, the inspiratory muscles relax and the elastic recoil of the lung tissue combined with intrathoracic pressure causes air to be pushed out of the lungs. There is little or no respiratory activity of the abdominals. When increased oxygen is required during physical activity e.g. when running, accessory muscles will activate to assist forced respiration.
There are number of muscles which work together during respiration. The major muscles to look at: 1.diaphragm and transversus abdominus, which will enable you to inhale and exhale 2.intercostal Muscles and transversus thoracic, which are responsible for both inhalation and exhalation, but are also maintaining the structure of your lung and your thorax and preventing it from collapsing on itself.
Oxygen and a source of Fuel/Energy, and a Cell. "Lactic Acid Burn", that occurs to overworked muscles, occurs during Respiration that takes place without enough oxygen at the time.
