Anaerobic Respiration

During bursts of strenuous exercise, when muscles contract to maximum possible effect, blood vessels supplying oxygen to muscle fibers are squeezes, limiting the delivery of oxygen.  Under these circumstances muscle fibers switch to anaerobic respiration, which does not require oxygen, to meet their energy needs.  It frees far less energy than aerobic respiration, but happens much more rapidly.
