“…In this regard, the increase in inspiratory muscle strength following IMT may have increased the oxygen volume and diffusion in the lungs by enabling these muscles to become more active, particularly during maximal exercise. Outcomes of previous studies that observed an increase in FVC, PI max , and VO2 peak without an increase in HR peak are also supporting the results of the present study 42,43 . Another potential reason for the observed increase in VO 2max could be that the patients became more accustomed to managing restricted breathing conditions following IMT.…”

IntroductionAlthough inspiratory muscle training (IMT) has proven effective in adult rheumatic diseases, its impact on juvenile idiopathic arthritis (JIA) remains unexplored. The present study aimed to investigate the effects of IMT in children with JIA.MethodsThirty‐three children (13–18 years) with JIA were divided into two groups as exercise (n = 17) and control (n = 16). The exercise group performed IMT at home daily for 8 weeks. The initial IMT load was set as 60% of maximal inspiratory pressure (PImax) and increased by %10 of the initial load every 2 weeks. The control group received no additional intervention. Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FVC/FEV1, PImax, and maximal expiratory pressure (PEmax) were evaluated. Peak oxygen consumption (VO2max), metabolic equivalents (METs), and maximal heart rate were measured with cardiopulmonary exercise test. Functional capacity and quality of life were assessed with 6‐min walk distance and Pediatric Quality of Life Inventory 3.0 Arthritis Module. All participants were evaluated at baseline and post‐treatment.ResultsFVC ( ↑ 0.20 (95% CI: 0.07/0.32) liters), FEV1 ( ↑ 0.14 (95% CI: 0.02/0.25) liters), PImax (↑19.11 (95% CI: 9.52/28.71) cmH2O), PEmax (↑12.41 (95% CI: 3.09/21.72) cmH2O), VO2peak (↑158.29 (95% CI: 63.85/252.73) ml/min), and METs (↑0.92 (95% CI: 0.34/1.49) [ml/kg/min]) significantly improved only in the exercise group (p < .05). The difference over time in FVC, FEV1, PImax, VO2peak, and METs were significantly higher in exercise group compared to control group (p < .05).ConclusionsIMT seems to be an effective option for improving respiratory functions and aerobic exercise capacity in JIA.

“…Low skeletal muscle mass is now an independent prognostic factor for patients with CHF ( 16 ). Early rehabilitation training can improve the quality of life and also reduce mortality and hospitalization rates in patients with mild-to-moderate CHF ( 17 ). Therefore, it is necessary to evaluate muscle quality quantitatively at an early stage.…”

ObjectiveTo assess the usefulness of gray-scale ultrasound (US) and shear wave elastography (SWE) in assessing the condition of the skeletal muscles in patients with chronic heart failure (CHF).MethodsWe prospectively compared 20 patients with clinically diagnosed CHF and a control population of 20 normal volunteers. The gastrocnemius medialis (GM) of each individual in the rest and the contraction position was assessed using gray-scale US and SWE. The quantitative US parameters including the fascicle length (FL), pinnation angle (PA), echo intensity (EI), and Young's modulus of the muscle were measured.ResultsIn the CHF group compared with the control group, in the rest position, there was a significant difference in EI, PA, and FL of the GM (P < 0.001), but no statistically significant difference in Young's modulus values (P > 0.05); however, in the contraction position, all parameters were statistically different between the two groups (P < 0.001). In the different subgroups of the CHF group grouped according to New York Heart Association staging (NYHA) or left ventricular ejection fraction (LVEF), there were no significant differences in ultrasound parameters in the rest position. However, during the contraction of GM, the smaller the FL and Young's modulus, the larger the PA and EI with the increase of NYHA grade or the decrease of LVEF (P < 0.001).ConclusionThe gray-scale US and SWE can provide an objective assessment of skeletal muscle status for CHF patients and are expected to be used to guide their early rehabilitation training and improve their prognosis.

Objective This systematic review and meta-analysis aimed to evaluate the effects of respiratory muscle training (RMT) on functional exercise capacity, health-related quality of life, respiratory muscle function and pulmonary function in individuals with ischemic heart disease (IHD). Methods The MEDLINE, Web of Science, Scopus, PEDro, CINAHL, Science Direct, and CENTRAL electronic databases were searched in January 2023. Randomized controlled trials published in English, Spanish, or Portuguese that were conducted to determine the effect of RMT versus passive control and/or sham RMT on the target variables in individuals with IHD, irrespective of age or sex, were included. Two reviewers performed the searches and extraction of the most relevant data. The quality and risk of bias for each included study was examined with the PEDro scale and Cochrane risk-of-bias tool. Results Thirteen studies (849 participants) were included. The meta-analysis showed a significant increase in peak oxygen consumption (mean difference [MD] = 2.18 mL·kg−1·min−1 [95% CI = 0.54 to 3.83]), inspiratory muscle strength (MD = 16.62 cm H2O [95% CI = 12.48 to 20.77]), inspiratory muscle endurance (standardized MD [SMD] = 0.39 [95% CI = 0.19 to 0.60]), and expiratory muscle strength (MD = 14.52 cm H2O [95% CI = 5.51 to 23.53]). There were no benefits in 6-minute walking distance (MD = 37.57 m [95% CI = −36.34 to 111.48]), health-related quality of life (SMD = 0.22 [95% CI = −0.16 to 0.60]), pulmonary function (forced vital capacity; MD = 2.07% of predicted value [95% CI = −0.90 to 5.03], or forced expiratory volume at the first second (MD = −0.75% of predicted value [95% CI = −5.45 to 3.95]). Conclusions This meta-analysis provided high- and moderate-quality evidence that inspiratory muscle training (IMT) improves inspiratory muscle strength and endurance, respectively; and very low-quality evidence for effects on peak oxygen consumption and expiratory muscle strength in individuals with IHD. No superior effects were found in the 6-minute walking test, health-related quality of life, or pulmonary function compared with the control group. Impact The results shown in this systematic review with meta-analysis will provide clinicians a better understanding of the effects of IMT in people with IHD. IMT could be integrated into the cardiac rehabilitation management, although more research is needed.
