Implication

Muscle afferent stimulation may contribute to ventilatory control; hypothesis-generating for human exercise physiology and clinical translation.

Key Points

The study aims to investigate how certain sensory receptors in the gastrocnemius muscle affect ventilation in dogs.
Anesthetized dogs received stimulation of muscle receptors in the gastrocnemius muscle.
Group III fibers and nonmedullated fibers were stimulated through local muscle manipulations.
Effect on ventilation was measured when medullated fibers were blocked via cooling or repetitive stimulation.
Reflex increase in ventilation occurred with stimulation of nonmedullated fibers and group III fibers.
Blocking medullated fibers still allowed reflex hyperventilation through nonmedullated fiber stimulation.
Local muscle manipulation (stretching, pressing, squeezing) enhanced reflexive ventilation responses.

Structured PICO

Population

Dogs anesthetized with Na pentobarbital

Intervention

Natural stimulation of sensory receptors (stretching, pressing, or squeezing the muscle locally) targeting endings of group III and nonmedullated fibers (C fibers)

Outcome

Reflex increase in ventilation (Ve)surrogate

Sensory endings of nonmedullated fibers in muscles can produce reflex hyperventilation when stimulated by mechanical means.
