In human physiology, the muscles of respiration are those muscles that contribute to inhalation and exhalation, by aiding in the expansion and contraction of the thoracic cavity.The diaphragm and, to a lesser extent, the intercostal muscles drive respiration during quiet breathing.Additional 'accessory muscles of respiration' are typically only used under conditions of high metabolic demand (e.g. exercise) or respiratory dysfunction (e.g. an asthma attack).dditional 'accessory muscles of respiration' are typically only used under conditions of high metabolic demand (e.g. exercise) or respiratory dysfunction (e.g. an asthma attack).
With the extra energy from the anaerobic respiration, the muscle cells are able to contract during vigorous exercise. When anaerobic respiration occurs, lactic acid is produced and it will build up in our muscles and eventually cause muscular pain and fatigue. The body needs to rest to recover after doing exercise.
