Mechanical constraints appear to require that locomotion and breathing be synchronized in running mammals. Phase locking of limb and respiratory frequency has now been recorded during treadmill running in jackrabbits and during locomotion on solid ground in dogs, horses, and humans. Quadrupedal species normally synchronize the locomotor and respiratory cycles at a constant ratio of 1:1 (strides per breath) in both the trot and gallop. Human runners differ from quadrupeds in that while running… Expand
A model of locomotor-respiratory coupling in quadrupeds.
TLDR
The concept that locomotor-respiratory coupling provides a basis for the appropriate matching of lung ventilation to running speed and metabolic power is strengthened. Expand
Impact Loading and Locomotor-Respiratory Coordination Significantly Influence Breathing Dynamics in Running Humans
TLDR
It is hypothesized that humans coordinate breathing and locomotion to minimize antagonistic loading of respiratory muscles, reduce work of breathing and minimize rate of fatigue, and the potential consequences of locomotor-ventilatory interactions for elite endurance athletes and individuals who are overweight or obese.

TLDR
The current state of knowledge of influences of locomotion upon respiratory system function is reviewed, including evidence for an energetic advantage to coordination of locomotor and respiratory cycles for flying birds and running mammals. Expand
Energetic consequences of coordinating wingbeat and respiratory rhythms in birds
TLDR
The hypothesis that there is a significant net saving obtained from reducing the mechanical interference between locomotion and ventilation by locomotor­respiratory coupling is supported by measuring the external work required to ventilate birds mechanically during simulated flight. Expand
Axial-Appendicular Dynamics and the Integration of Breathing and Gait in Mammal
TLDR
A biomechanical model for locomotor-respiratory coupling (LRC) in galloping mammals in which gait and breathing cycles are phase-locked on a 1:1 basis is proposed and the prediction that large mammals will breathe relatively faster and with relatively smaller lung volumes when galloping than small species is predicted.

Independent respiratory and locomotor rhythms in running mice
TLDR
This work examines the specifications of respiratory changes during running in mice, the premier model for investigating, in a standardized manner, complex integrative tasks including adaptive breathing, and highlights a hardwired mechanism that sets respiratory frequency independently of limb movements but in relation with the engaged locomotor program. Expand
Absent phasing of respiratory and locomotor rhythms in running mice
TLDR
Exercise hyperpnoea can operate, at least in mice and in the presently examined running regimes, without phasic constraints from limb movements, according to a wide range of trotting speeds on a treadmill. Expand
The synchronization of ventilation and locomotion in horses (Equus caballus).
TLDR
Ciné film and synchronized records of respiratory flow were obtained from Thoroughbred racehorses cantering on a treadmill at speeds of 9 and 11 m s-1 and it would seem likely that back flexion is likely to contribute towards driving ventilation but loading of the thorax and the visceral piston mechanism do not.

TLDR
Mechanical interactions between running, breathing and liver oscillations in the domestic rabbit are recorded using synchronized videographic, cineradiographic and pneumotachographic techniques and are generally consistent with the theoretical vibration mechanics model for liver motion and with the pneumatic stabilization hypothesis that the lungs serve an important role in the stabilization of the thorax during locomotion.

Thoracic adaptations for ventilation during locomotion in humans and other mammals
TLDR
Experimental and comparative data show that humans and other animals selected for long-distance running convergently evolved adaptations to augment diaphragmatic breathing with thoracic movements. Expand

Gait and the energetics of locomotion in horses
It seems reasonable that quadrupeds should change gait from a walk to a trot to a gallop in such a way as to minimize their energy consumption, as human beings are known1 to change from a walk to aExpand
The energetic cost of bipedal hopping in small mammals
TLDR
The purpose of the present study was to extend the assessment of the metabolic expense of bipedal hopping to a broader range of body sizes and mammalian taxa and found that when properly trained for sustained running, none of the three species deviated from the expected quadrupedal pattern relating cost of locomotion to running speed, even while running fully bipedally.

TLDR
At speeds up to 1.67 m/s, respiratory frequency is not tightly locked to stepping frequency in cats; however, the occurrence of entrainment in some instances clearly indicates the existence of neural circuitry linking these two pattern generators. Expand

Design of the mammalian respiratory system. II. Measuring maximum aerobic capacity.
TLDR
It is found that Vo2 increased linearly with tread-speed up to a maximal rate and then remained unchanged with further increases in speed in nine species and the treadmill procedure is valid for determining the allometric relationship between Vo2max and Mb. Expand
Ventilatory and gas exchange responses to cycling with sinusoidally varying pedal rate.
TLDR
The ventilatory responses to these forcings are inconsistent with an appreciable role for neurally mediated influences from the exercising limbs and provide further evidence that the exercise hyperpnea is linked to CO2 flow to the central circulation. Expand

TLDR
It is concluded that the lumbar spine contributes substantially to step length and limb speed during galloping and half‐bounding steps and the epaxial and abdominal musculature may also act as elastic bodies. Expand
