马的呼吸周期和四肢周期之间的相位关系在马的跑中和跑动中得到了证明。测量了正常马在野外走、跑、跑、跑时的腹内压、呼吸音、每次动作的触地时间和胸腔容积的变化。这些参数的相关性确定了建立马肺通气和运动耦合的主要机械环节。腹肌收缩的力度和程度与呼吸和肢体循环耦合，使肺通气的机制与运动的机制同步，从而实现强制呼气。
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 feat 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.
