Physiological basis of brief, intense interval training to enhance maximal oxygen uptake: a mini-review

Brief, intense interval training describes a style of exercise characterized by short bouts of strenuous effort interspersed with recovery periods. The method increases whole body maximal oxygen uptake (V̇o_2max), but the underlying physiological basis is unclear. V̇o_2max represents the functional limit of the integrative oxygen cascade, which refers to the physiological steps involved in oxygen transport and utilization from atmospheric air to …
