Purpose: This study aimed to analyze the effect of a Pilates protocol on respiratory muscle strength and heart rate variability (HRV) in patients with type 2 diabetes. Method: A randomized clinical trial (RBR-2gc2qj) was conducted with a type 2 diabetic target population. Patients practiced the Pilates protocol for 8 weeks, with two visits per week. The variables tested were maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), and HRV (time and frequency domains). All variables were tested for normal distribution. Using SPSS 21.0, analysis of variance was performed for variables with normal distribution, and the Wilcoxon and Friedman tests were used for variables that did not show a normal distribution, with a 5% significance level. Results: Forty-four participants were included in the study (intervention group: 22; control group: 22; mean age: 61.23 ± 8.49 years), most of whom were female (77.3%), married or in a consensual union (59.1%), had complete literacy (31.8%), and had an average body mass index of 26.96 ± 4.35 kg/m2. There were no significant differences in MIP and MEP before and after the protocol between the intervention and control groups. Regarding HRV, there were significant differences in autonomic modulation, especially between the moments before and during exercise and between the moments during and after exercise; however, it was not possible to determine which system (sympathetic or parasympathetic) is most involved in these changes. Conclusion: The exercise protocol based on the Pilates method did not alter respiratory muscle strength but promoted changes in HRV, especially between the moments before and during exercise and during and after exercise.

Abstract Purpose The present study was conducted to compare the effects of low volume of high intensity interval training (LVHIIT) and high volume of high intensity interval training (HVHIIT) on heart rate variability (HRV) as a primary outcome measure, and on maximum oxygen consumption (VO2max), body composition, and lower limb muscle strength as secondary outcome measures, in sedentary young women. Methods Thirty-six participants were recruited in this study. The LVHIIT group (n = 17) performed one 4-min bout of treadmill running at 85%–95% maximum heart rate (HRmax), followed by 3 min of recovery by running at 70% HRmax, three times per week for 6 weeks. The HVHIIT group (n = 15) performed four times 4-min bouts of treadmill running at 85%–95% HRmax, interspersed with 3-min of recovery by running at 70% HRmax, 3 times per week for 6 weeks. All criterion measures were measured before and after training in both the groups. Results Due to attrition of four cases, data of 32 participants was used for analysis. A significant increase in high frequency (HF) power (p < 0.001) and decrease in the ratio of low frequency to high frequency power (LF/HF) ratio (p < 0.001) in HRV parameters, was observed post-HVHIIT, whereas, these variables did not change significantly (HF: p = 0.92, LF/HF ratio: p = 0.52) in LVHIIT group. Nevertheless, both the interventions proved equally effective in improving aerobic capacity (VO2max), body composition, and muscle strength. Conclusion The study results suggest that both LVHIIT and HVHIIT are equally effective in improving VO2max, body composition, and muscle strength, in sedentary young women. However, HVHIIT induces parasympathetic dominance as well, as measured by HRV.

UNSTRUCTURED The aim of this study was to evaluate the effects of the use of both surgical masks and FFP2 respirators on the inspiratory muscle strength, metabolic parameters, heart rate, subjective perceived exertion and dyspnea perception, before and during 30 minutes stable load exercise at “conversational level”. A randomized cross-over study was carried out. Nineteen healthy adults completed 3 conditions (without mask, with surgical mask or FFP2 respirator) during a 30-minute steady-state-test at the lactate threshold intensity. Inspiratory muscle strength was measured before and after the test, and metabolic parameters, heart rate, subjective perceived exertion and dyspnea perception were collected at baseline, during and after the test. There was a significant reduction in inspiratory muscle strength after the 30-minutes-test in all conditions (control:-6.26 mmHg, p<0.5; surgical mask:-8.55mmHg, p<0.01; FFP2respirator:-12.42 mmHg, p<0.001), but without significant differences between them (p=0.283). Data showed a statistically significant effect for time, but did not show a statistically significant interaction between condition and time for heart rate (p=0.674), oxygen saturation (p=0.297), blood lactate level (p=0.991), rating perceived exertion (p=0.734) and dyspnea (p=0.532) comparisons. The present study findings suggested that inspiratory muscle strength and physiological parameters during “conversational level” exercise were not impaired under wearing masks in healthy, non-smoking young adults, who participated in regular recreational physical activity for at least 3 days per week.

Abstract Purpose Cystic Fibrosis (CF) is a multisystem disease associated with symptoms such as dyspnoea, tachycardia and tachypnea that may be related to changes in autonomic function and sensitive to improvement following inspiratory muscle training (IMT). The aim of the present study was to investigate the effect of IMT on heart rate variability (HRV) and respiratory function in children. Methods Five CF and five matched controls (40% boys) performed a 4-weeks IMT programme, involving 30 breaths, twice a day. Weeks 1–2 of training were set at 40% of a participant’s maximal strength index (S.Index), with week’s 3–4 set at 50%. Participants wore an ActiHeart for three consecutive days at baseline and post-intervention and indices of HRV were derived. Standard measures of lung function were obtained along with health-related quality of life (HRQoL) using the CF-specific questionnaire (CFQ-R). Results IMT elicited clinically meaningful increases in respiratory muscle strength and respiratory symptom domain scores, but no improvements in respiratory volume, irrespective of group. Similarly, no significant improvements were found in HRQoL despite 62.5% of the population increased their HRQoL score. Post-intervention, CF participants showed a clinically meaningful decrease in the very low frequency (VLF) domain. Conclusion These results may indicate clinically meaningful changes in HRV and inspiratory muscle strength following a 4-week IMT intervention, although a more powerful study is required to draw further conclusions. Indeed, the trends for improved HRQoL support the need for such studies to ascertain the potential therapeutic role of IMT in those with CF.

Background Several reports suggest that interpleural local anesthetics may have deleterious effects on respiratory function. The current study investigated the effects of interpleural bupivacaine on human respiratory muscles and lung function. Methods Thirteen patients (55 +/- 4 yr old) with normal respiratory function and scheduled for cholecystectomy entered the study before surgery. Respiratory parameters were compared before and after the interpleural administration of 20 ml 0.5% bupivacaine plus 1:200,000 epinephrine while patients were supine; we evaluated breathing pattern, dynamic and static lung volumes, airway conductance, maximal inspiratory pressures (at the mouth; at the esophagus [Pessniff]; at the abdomen [Pgasniff]; and transdiaphragmatic [Pdisniff]), functional reserve (tension-time index) of the diaphragm, and maximal expiratory pressures (at the mouth; at the esophagus [Pescough]; and at the abdomen [Pgacough]). Hemoglobin oxygen saturation by pulse oximetry, heart rate, and mean arterial pressure were continuously monitored. Results Respiratory rate (15 +/- 1 to 19 +/- 1 breaths/min; P &lt; 0.01) and heart rate (78 +/- 3 to 83 +/- 3 beats/min; P &lt; 0.01) were slightly increased. Dynamic and static lung volumes, airway conductance, hemoglobin saturation, and the remaining breathing pattern parameters were unchanged. Regarding respiratory muscles, maximal inspiratory pressure at the mouth, Pessniff, and tension-time index of the diaphragm did not change. Pdisniff decreased slightly (102 +/- 10 to 92 +/- 10 cmH2O; P &lt; 0.05) because of a change in Pgasniff (24.2 +/- 7.4 to 18.4 +/- 6.8 cmH2O; P &lt; 0.05). Maximal expiratory pressure at the mouth remained unaltered, but Pgacough decreased (108 +/- 10 to 92 +/- 8 cmH2O; P &lt; 0.01), and Pescough showed a trend to decrease (92 +/- 13 to 78 +/- 10 cmH2O; P = 0.074). Conclusions In our experimental conditions, interpleural bupivacaine did not significantly change lung function or inspiratory muscle strength but induced a slight decrease in abdominal muscle strength. Although this effect was minimal, its clinical relevance needs to be evaluated further in patients with impaired respiratory function.

Introduction: The number of greenhouse vegetable businesses has been increasing recently. Most tasks in the greenhouses are still done manually and associated with physical stress. Our objective was to study characteristics of the circulatory and muscular systems of female greenhouse workers in the course of their work and depending on the length of service at the enterprise. The materials included some indices of the functional state of the organism of greenhouse workers growing vegetables such as the heart rate, systolic and diastolic blood pressure, muscle strength and endurance of the right hand in the process of harvesting and removing plant debris. The statistical data processing was performed using the Microsoft Excel 2016 software. The results of the study showed that the work of greenhouse vegetable growers caused gradual changes in the functioning of the cardiovascular and neuromuscular systems of the body. The most significant increase in the heart rate and blood pressure and the decrease in muscle strength and endurance were observed among the greenhouse workers with 15 or more years of work experience. We also observed a significant decrease in muscle strength of the right hand among the workers with the shortest record of service (< 5 years). The study of the functional state of the cardiovascular and muscular systems helped establish the most potentially efficient group of greenhouse vegetable growers: the smallest fluctuations of the measured indices were observed in the women with 6-9 years of service. Conclusions: Our findings prove the necessity of systematic science-based measures of disease prevention in female greenhouse employees.

Introduction: Sedentary behaviour or physical inactivity has been relatively prevalent among young adults globally. Multiple studies pointed out that Malaysia has been listed as one of the Asian countries with high prevalence of inactivity. Objective: This study aimed to examine the heart rate variability (HRV) and muscle strength among young adults in order to identify the early impact of this behaviour on their physiological and physical health. Method: This cross-sectional study involved 185 healthy male adults aged 18-25 years old. Participants’ height and body compositions were measured and their level of physical activities were obtained using Short Questionnaire to Assess Health (SQuASH). Those with less than 150 minutes per week of physical activity engagement were classified as sedentary. Their HRV was analysed as a determinant for early physiological change that was influenced by the sedentary behaviour. Muscle strength of upper and lower body was assessed via handheld dynamometer to identify the physical fitness associated to the behaviour. Results: Among the participants that volunteered in this study, approximately 44% were classified as sedentary. Analyses revealed that those with sedentary behaviour had lower variability of their HRV and lower muscle strength as compared to those who engaged with at least 150 minutes per week of physical activities. Conclusion: The highlighted evidence of the difference on parameters of HRV and muscle strength with this behaviour suggested that these parameters were suitable parameters to be utilised in determining subclinical improvement on health with any intervention to curb sedentary behaviour.

Background: Stroke is a neurological disease that causes sudden loss of brain functions. One of the most important symptoms is hemiparesis, which due to the weakness of the trunk promotes a decrease in diaphragmatic power and impairs pulmonary function. In addition to the respiratory system, stroke can lead to impairment of the cardiovascular system. This occurs when the Autonomic Nervous System is affected, increasing the risk of the development of Heart Rate Variability due to sympathetic hyperactivity, this condition may predict an unfavorable prognosis after stroke. Case presentation: The aim of this study was to evaluate the variability of heart rate and respiratory muscle strength in a 61-year-old female patient diagnosed with a stroke three months prior to the study submitted to Neurofeedback training. That’s the first report of this kind in the literature. Cardiopulmonary evaluation was performed with a focus on heart rate and respiratory muscle strength before and after an intervention with five brain training sessions using the Neurofeedback BrainLink LITE. Conclusion: After therapy, significant alterations in the Delta wave increase and reduction of the Alpha wave were observed, also changes in the Autonomic Nervous System parameters were observed, with reduction of the sympathetic activity and increase of the parasympathetic activity, along with that, a reduction in the stress index was observed. The intervention was still positive in the improvement of respiratory parameters, with an increase in the overall inspiratory muscle strength index (S-Index) and peak inspiratory flow (PIF). It is suggested that Neurofeedback is efficient in recovering functions related to Autonomic Nervous System and respiratory system.
