“…Hence, this study evaluated the effect of TU-Breath Training with 40% of MIP in hypertensive participants and observed that BP decreased at 40% MIP. Therefore, these results by McConnell and Griffiths [19] and Archiza et al [18] can be partially compared with this study. Increases in RSA might be resulting from increases in intrathoracic pressure and that improving baroreceptors or changes in the breathing pattern after resistive loading [21].…”

“…This study aimed to develop the prototype of respiratory training (TU-Breath Training) and also determine Similarly, several studies have shown that acute effects of different inspiratory muscle-resistive loading on cardiovascular responses; it has been found that low intensities (i.e., 30% of MIP during inspiratory-resistive loading) were associated with improvement in parasympathetic sinus node modulation and the influence of the respiratory sinus arrhythmia (RSA) [18]. In addition, HR and BP have been increased after 60% of MIP, which is of high intensities [19].…”

Purpose The purpose of this study is to develop a prototype of a novel respiratory device that we validated and assessed clinically and examined the effect of prototype of respiratory device on blood pressure (BP). Methods Prototype of respiratory device (TU-Breath Training) was designed with pressure cuff and application software was created. The immediate effect of resisted breathing was determined in 20 adults with high BP (systolic BP ≥ 130 mmHg and diastolic BP ≥ 90 mmHg). A crossover study was designed. A total of 20 eligible participants were asked to sit quietly for 10 min. Heart rate (HR), BP, and oxygen saturation (SpO2) were measured and recorded. After the resting period, all participants were randomized and counterbalanced for undergoing the set of inspiratory muscle training by TU-Breath Training and control group. A set of respiratory training were composed of 10 times per set for three sets, while the control group was asked to sit for 10 min. Results After inspiratory training, both the systolic and diastolic BP decreased significantly. Compared with control group, using TU-Breath Training decreased systolic BP (−7.00 ± 5.93 mmHg) and diastolic BP (−5.95 ± 8.88 mmHg), but did not show differences in HR and SpO2. Conclusion The study indicated that in high-BP participants, the prototype of respiratory device (TU-Breath Training) elicits decreased BP.

Can Reactivity of Heart Rate Variability Be a Potential Biomarker and Monitoring Tool to Promote Healthy Aging? A Systematic Review With Meta-Analyses

Background: Monitoring phasic responses of heart rate variability (HRV) in terms of HRV reactivity [i. e., the absolute change from resting state to on-task (i.e., absolute values of HRV measured during exercise)] might provide useful insights into the individual psychophysiological responses of healthy middle-aged to older adults (HOA) to cognitive and physical exercises.Objectives: To summarize the evidence of phasic HRV responses to cognitive and physical exercises, and to evaluate key moderating factors influencing these responses.Methods: A systematic review with meta-analyses was performed. Publications up to May 2020 of the databases Medline (EBSCO), Embase, Cochrane Library, CINAHL, Psycinfo, Web of Science, Scopus, and Pedro were considered. Controlled clinical trials and observational studies measuring phasic HRV responses to cognitive and/or physical exercises in HOA (≥50 years) were included.Results: The initial search identified 6,828 articles, of which 43 were included into the systematic review. Compared to resting state, vagally-mediated HRV indices were significantly reduced during all types of exercises [Hedge's g = −0.608, 95 % CI (−0.999 to −0.218), p = 0.002] indicating a significant parasympathetic withdrawal compared to rest. The key moderating variables of these responses identified included exercise intensity for physical exercises, and participant characteristics (i.e., level of cognitive functioning, physical fitness), task demands (i.e., task complexity and modality) and the individual responses to these cognitive challenges for cognitive exercises. In particular, higher task demands (task complexity and physical exercise intensity) were related to larger HRV reactivities. Better physical fitness and cognition were associated with lower HRV reactivities. Additionally, HRV reactivity appeared to be sensitive to training-induced cognitive and neural changes.Conclusion: HRV reactivity seems to be a promising biomarker for monitoring internal training load and evaluating neurobiological effects of training interventions. Further research is warranted to evaluate the potential of HRV reactivity as a monitoring parameter to guide cognitive-motor training interventions and/or as a biomarker for cognitive impairment. This may facilitate the early detection of cognitive impairment as well as allow individualized training adaptations that, in turn, support the healthy aging process by optimizing individual exercise dose and progression of cognitive-motor training.

“…Still, the authors reported favorable outcomes on the ANS operation. However, it has been already demonstrated that a single session of this exercise modality with high loads caused higher SNA and less parasympathetic activation when compared to the session with lower loads in healthy elderly individuals 25,26 , which may confer higher cardiovascular risk to the patients. Thus, new studies should clarify the acute and chronic physiological effects of IMT with high loads and/or high intensity for different populations.…”

| 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.
