The phase relationship between the periods of the respiratory and limb cycles is demonstrated in the horse ridden in the field at the canter and gallop. Changes in intra-abdominal pressure, respiratory sounds, periods of ground contact of each foot and volume changes of the rib cage were measured in the normal horse exercised at the walk, trot, canter and gallop in the field. Correlation of these parameters identifies the major mechanical link establishing the coupling of lung ventilation and locomotion in the horse. The force and extent of contraction of the abdominal muscles couples the respiratory and limb cycles so that the mechanics of lung ventilation are synchronized with the mechanics of locomotion to achieve forced expiration.
