Key result
A single bout of high intensity inspiratory muscle strength training had no acute effect on blood pressure but significantly suppressed sympathetic nervous activity, with greater magnitude in women.
Why the study?
While 6 weeks of high intensity, low volume inspiratory muscle strength training lowers BP and systemic vascular resistance, the acute response to IMST remains unknown.
Does a single bout of high intensity inspiratory muscle strength training acutely affect blood pressure, heart rate, and sympathetic nervous activity in healthy young adults?
Does a single bout of high intensity inspiratory muscle strength training acutely affect blood pressure, heart rate, and sympathetic nervous activity in healthy young adults?
A single bout of high-intensity inspiratory muscle strength training acutely suppresses sympathetic nervous activity, particularly in women, without acutely altering blood pressure.
Previous studies show 6 weeks of high intensity, low volume inspiratory muscle strength training (IMST) lowers blood pressure (BP) and systemic vascular resistance in young adults. However, the acute response to IMST is unknown. We characterized BP, heart rate, and sympathetic nervous activity (SNA) in healthy young adults at baseline, during IMST, and in recovery. There was no acute effect of IMST on BP, however, there was significant IMST-related suppression of SNA that was of greater magnitude in women than men.

DeLucia et al. (2021) studied Healthy. High intensity inspiratory muscle strength training (IMST) vs. Baseline and recovery was evaluated on Blood pressure, heart rate, and sympathetic nervous activity (SNA). A single bout of high intensity inspiratory muscle strength training had no acute effect on blood pressure but significantly suppressed sympathetic nervous activity, with greater magnitude in women.
