“…Recently, we reported that healthy (normotensive) adults and adults with sleep apnoea who perform inspiratory muscle training (IMT) each day for 6 weeks exhibit declines in systolic (SBP) and diastolic blood pressure (DBP; Vranish, & Bailey, , ). Apart from the ability to lower systolic and diastolic blood pressure over a short time course (4–6 weeks) and the abbreviated format of the daily training (∼5 min day −1 ), there are several other features of IMT that set it apart from more traditional aerobic exercise (i.e.…”

Previous work has shown that inspiratory muscle training (IMT) lowers blood pressure after a mere 6 weeks, identifying IMT as a potential therapeutic intervention to prevent or treat hypertension. Here, we explore the effects of IMT on respiratory muscle strength and select cardiovascular parameters in recreationally active men and women. Subjects were randomly assigned to IMT (n = 12, 75% maximal inspiratory pressure) or sham training (n = 13, 15% maximal inspiratory pressure) groups and underwent a 6-week intervention comprising 30 breaths day , 5 days week . Pre- and post-training measures included maximal inspiratory pressure and resting measures of blood pressure, cardiac output, heart rate, spontaneous cardiac baroreflex sensitivity and systemic vascular resistance. We evaluated psychological and sleep status via administration of the Cohen-Hoberman inventory of physical symptoms and the Epworth sleepiness scale. Male and female subjects in the IMT group showed declines in systolic/diastolic blood pressures (-4.3/-3.9 mmHg, P < 0.025) and systemic vascular resistance (-3.5 mmHg min l , P = 0.008) at week 6. There was no effect of IMT on cardiac output (P = 0.722), heart rate (P = 0.795) or spontaneous cardiac baroreflex sensitivity (P = 0.776). The IMT subjects also reported fewer stress-related symptoms (pre- versus post-training, 12.5 ± 8.5 versus 7.2 ± 9.7, P = 0.025). Based on these results, we suggest that a short course of IMT confers significant respiratory and cardiovascular improvements and parallel (modest) psychological benefits in healthy men and women.

“…These improvements in vascular compliance, therefore, could contribute to slowing down the decrease of vascular elasticity as a normal process during aging, as well as to reducing cardiovascular risk [3]. Although the mechanism for RMT to modify vascular plasticity remains to be determined, supporting evidence comes from the findings that RMT reduces systolic and diastolic blood pressure in both normotensive and hypertensive adults [4,5]. Furthermore, RMT restores impaired peripheral blood flow to resting and exercising limbs in chronic heart failure patients.…”

Unhealthy lifestyle habits can negatively affect cardiopulmonary parameters and contribute to respiratory muscle weakness. • This case presents a 47-year-old female with impaired pulmonary function and elevated cardiovascular risk. • Two weeks of respiratory muscle training ○ improved pulmonary function (FEV1) by 9%, ○ reduced the estimated lung age by 6 years, ○ and increased vascular elasticity by 86%. • The findings highlight the effectiveness of RMT to slow cardiopulmonary decline and to reduce the risk of cardiovascular disease. AbstractThis case study highlights the usefulness of respiratory muscle training (RMT) in improving pulmonary and cardiovascular parameters as an early intervention to cardiopulmonary decline. We suggest RMT as an easily accessible, cost-and time-effective approach to support a healthy lifestyle.Many lifestyle and occupational habits negatively impact physical and mental health, increasing the risk of cardiovascular and other diseases. While larger institutions fulfill occupational health requirements to ensure their employees' wellbeing at work, smaller business workers and entrepreneurs may neglect initial signs of stress or physical decline, putting themselves at increased risk. Early detection of compromised cardiopulmonary health or fitness has the potential to flag up indications for early interventions and reduce the risk of disease onset and progression.Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted:

“…The IMT consists on performing inspirations against a resistance through many mechanisms, it is an easily applied and low-cost intervention, which is also considered clinically significant in the rehabilitation scenario 11 . Studies with different populations point out the improvement of inspiratory muscle force after performing the IMT [9][10][11][12][13][14][15] . In addition, functional capacity and blood pressure also seem to be favored by this training modality 9,13 .…”

| The autonomic nervous system dysfunction has an important role on the physiopathology of some diseases. A possible option to improve the autonomic control is the inspiratory muscle training (IMT). The aim of this study was to systematically review the available literature about the effects of this training modality on autonomic control. A search was performed for controlled and randomized clinical trials on database MEDLINE, PEDro, SciELO and LILACS by two independent reviewers, who also evaluated the methodologic quality (PEDro scale). 181 articles were found and, after elegibility criteria analysis, four studies were included. The included studies showed good methodological quality and assessed the effect of IMT on the autonomic control of participants with risk factors for cardiovascular disease. The autonomic control was evaluated by heart rate variability (HRV) analysis and by noradrenaline plasma levels. The IMT improved autonomic control in 3 studies,reducing the sympathetic nervous system (noradrenaline plasma levels; LF nu -HRV) and increasing the vagal nervous system (HF un -HRV). It is concluded that IMT may be a therapeutic alternative to improve the autonomic control.
