Improvement in ventilatory muscle function with running

E P Robinson, J M Kjeldgaard

    Journal of Applied Physiology: Respiratory, Environmental and Exercise Physiology
    |June 1, 1982

    Summary

    Running significantly improves ventilatory muscle strength and endurance in sedentary adults. This study shows enhanced maximum voluntary ventilation and maximum sustainable ventilatory capacity after a 20-week running program.

    Area of Science:

    • Exercise Physiology
    • Respiratory Medicine

    Background:

    • Sedentary lifestyles are associated with reduced physical capacity.
    • The impact of specific aerobic exercises like running on ventilatory muscles requires further investigation.

    Purpose of the Study:

    • To investigate the effects of a running program on ventilatory muscle strength and endurance.
    • To compare changes in respiratory function between a running group and a control group.

    Main Methods:

    • 11 sedentary adults participated in a 20-week physical fitness program involving running.
    • 12 healthy volunteers served as a control group.
    • Measurements included maximum expiratory pressure (Paomax), maximum voluntary ventilation (MVV), and maximum sustainable ventilatory capacity (MSVC) at baseline, 10 weeks, and 20 weeks.

    Main Results:

    • The running group showed significant increases in MSVC and MVV after 10 weeks.
    • After 20 weeks, the running group exhibited significant improvements in expiratory Paomax (14.4%), MVV (13.6%), and MSVC (15.8%).
    • No significant changes were observed in the control group over the 20-week period.

    Conclusions:

    • Running is an effective exercise modality for enhancing ventilatory muscle strength and endurance.
    • These findings suggest that incorporating running into physical fitness programs can benefit respiratory health in previously sedentary individuals.
