Ventilatory pattern during handgrip on normal man

E Bosisio, F Panzuti, M Sergi

    Respiration; International Review of Thoracic Diseases
    |January 1, 1981

    Summary

    Isometric handgrip exercise significantly increases pulmonary ventilation in healthy individuals. This response is primarily driven by enhanced neural inspiratory drive, leading to greater mean inspiratory flow.

    Area of Science:

    • Physiology
    • Respiratory Medicine
    • Exercise Science

    Background:

    • Isometric handgrip exercise is a common task that elicits physiological responses.
    • Understanding the neural control of breathing during exertion is crucial for respiratory health.

    Purpose of the Study:

    • To investigate the ventilatory response to isometric handgrip exercise.
    • To determine the primary mechanisms driving changes in pulmonary ventilation during this task.

    Main Methods:

    • Studied 7 healthy young subjects performing isometric handgrip at 50% maximum voluntary contraction.
    • Measured ventilatory parameters including tidal volume over inspiratory time (Vt/Ti) and inspiratory time over total breath time (Ti/Ttot).

    Main Results:

    • Significant increase in pulmonary ventilation (VE) observed during isometric handgrip.
    • Both mean inspiratory flow (Vt/Ti) and the timing component of ventilation (Ti/Ttot) increased.
    • The rise in mean inspiratory flow was more pronounced than the change in ventilatory timing.

    Conclusions:

    • Isometric handgrip exercise stimulates a significant increase in pulmonary ventilation.
    • The predominant mechanism is an enhanced neural inspiratory drive, leading to increased mean inspiratory flow.
