Background: Respiratory muscle training (RMT) has been proposed as a beneficial means of improving respiratory muscle strength (RMS) and respiratory muscle fatigue (RMF) in athletes. Aims and Objective: The aim of this study was to determine the effects of a 12-week specific RMT program on the RMS, RMF and rowing ergometer performance in highly- trained rowers. Materials and Methods: Twenty professional rowers aged 20-35 years were recruited for the study during the competitive period and randomly grouped into an experimental (n=11) or control (n=9) group. Baseline measurements of maximal inspiratory and expiratory mouth pressures were obtained with a portable handheld mouth pressure meter while performance was assessed by 2000m and 5000m rowing ergometer machine. Subsequently rowers in the experimental group were prescribed a novel RMT program comprising of specific breathing and abdominal muscle exercises while the control group was prescribed a “general exercise program” for non- respiratory muscles for a 12-week period. RMF was assessed by calculating the difference between the pre-exercise and post-exercise mouth pressures. Results: Respiratory muscle strength improved overtime in the experimental and the control group following the respective training programs (p<0.05) with the experimental group showing higher RMS and lower RMF. However, there were no statistically significant differences in RMS and RMF between the two groups (P>0.05). More importantly, rowing ergometer performance improved significantly in the experimental group compared to the control (p<0.01). Conclusion: The results suggest that the novel RMT program had a significant effect in improving rowing performance, although the effect on RMS and RMF was not significant.

Abstract Background Motor impairments caused by stroke result in impaired diaphragmatic and respiratory muscle function, changes in thoracic biomechanics on the hemiparetic side ultimately resulting in decreased efficiency of lung ventilation. This study aimed to examine the efficacy of chest expansion resistance exercise (CERE) on respiratory function, trunk control ability, and balance in patients with chronic stoke. Following a purposive sampling, thirty-five patients with chronic stroke were randomly allocated into two groups, i.e., the experimental group receiving CERE with conventional therapy and the control group receiving conventional therapy alone. Both the groups received therapy four times per week for a period of four weeks (total 16 sessions). Following assessments were done before and after treatment in both the groups: chest expansion ( axillary, nipple, xiphisternal levels) using measure tape, respiratory muscle strength using micro-respiratory pressure meter, trunk control using the Trunk Impairment Scale, and balance using mini-Balance Evaluation Systems Test. Results Both groups had 17 participants each (n = 34, drop-outs = 1) consisting of 12 males and 5 females having a mean age of 56.5 ± 12.98 years and 59.7 ± 10.2 years, respectively. Intra-group analysis showed a statistically significant increase in mean values of chest expansion, respiratory muscle strength, trunk control ability, and balance in the experimental group whereas the control group showed improvement only in trunk control ability and balance. Inter-group comparison revealed a better improvement in all the outcome variables in experimental group compared to the control group. Conclusions Based on these results, this study proved that CERE was more effective in improving respiratory function, trunk control, and balance in patients with chronic stroke.

Chronic obstructive lung disease (COPD) is a chronic lung pathology that leads to respiratory muscle weakness and decreased function capacity. Patients need to have pulmonary rehabilitation to increase respiratory muscle strength. The aim of the study was to assess the effect of artificial respiratory muscle training (ARMT) on respiratory muscle function and exercise performance in chronic obstructive pulmonary disease (COPD). Thirty patients in the mild to moderate COPD stage were randomly classified into an ARMT (n = 10), a control group (n = 10), and a standard respiratory muscle training group (SRMT; n = 10) by following the blind procedure. The control group received no training. The training groups, however, were trained at home for 30 min per day, every day, for 6 weeks. The measurement analyses included spirometry, an inspiratory muscle strength examination, and an exercise performance test. Exercise performance was evaluated by a 6 min walk test (SWT). The results showed that the maximal inspiratory pressure (PImax) and the maximal expiratory pressure (PEmax) were observed to have significantly increased in both the ARMT group and the SRMT group compared with the control group (p < 0.05). Moreover, the ARMT group was found to have significantly increased the 6 min walking distance in comparison with the control group. However, the ARMT group and the SRMT group did not differ significantly in those parameters. We conclude that it would be possible for the ARMT group among COPD patients to have improved respiratory muscle strength and increased capacity to walk.

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.

The avoidance of respiratory muscle fatigue and its repercussions may play an important role in swimmers’ health and physical performance. Thus, the aim of this study was to investigate whether a six-week moderate-intensity swimming intervention with added respiratory dead space (ARDS) resulted in any differences in respiratory muscle variables and pulmonary function in recreational swimmers. A sample of 22 individuals (recreational swimmers) were divided into an experimental (E) and a control (C) group, observed for maximal oxygen uptake (VO2max). The intervention involved 50 min of front crawl swimming performed at 60% VO2max twice weekly for six weeks. Added respiratory dead space was induced via tube breathing (1000 mL) in group E during each intervention session. Respiratory muscle strength variables and pulmonary and respiratory variables were measured before and after the intervention. The training did not increase the inspiratory or expiratory muscle strength or improve spirometric parameters in any group. Only in group E, maximal tidal volume increased by 6.3% (p = 0.01). The ARDS volume of 1000 mL with the diameter of 2.5 cm applied in moderate-intensity swimming training constituted too weak a stimulus to develop respiratory muscles and lung function measured in the spirometry test.

Objective: To investigate the effects of inspiratory muscle training on pulmonary function, respiratory muscle strength and functional capacity in patients with atrial fibrillation. Design: Prospective randomized controlled single-blind study. Setting: Cardiology department of a university hospital. Subjects: A total of 38 patients with permanent atrial fibrillation were randomly allocated to either a treatment group ( n = 19; age 66.2 years (8.8)) or a control group ( n = 19; age 67.1 years (6.4)). Methods: The training group received inspiratory muscle training at 30% of maximal inspiratory pressure for 15 minutes twice a day, 7 days a week, for 12 weeks alongside the standard medical treatment. The control group received standard medical treatment only. Spirometry, maximal inspiratory and expiratory pressures and 6-minute walking distance was measured at the beginning and end of the study. Results: There was a significant increase in maximal inspiratory pressure (27.94 cmH2O (8.90)), maximal expiratory pressure (24.53 cmH2O (10.34)), forced vital capacity (10.29% (8.18) predicted), forced expiratory volume in one second (13.88% (13.42) predicted), forced expiratory flow 25%–75% (14.82% (12.44) predicted), peak expiratory flow (19.82% (15.62) predicted) and 6-minute walking distance (55.53 m (14.13)) in the training group ( p < 0.01). No significant changes occurred in the control group ( p > 0.05). Conclusion: Inspiratory muscle training can improve pulmonary function, respiratory muscle strength and functional capacity in patients with atrial fibrillation.

OBJECTIVE: Respiratory muscle weakness is a functional repercussion of chronic lung disease (CLD). The objective of this study was to assess the effects of home-based respiratory muscle training (RMT) in children and adolescents with CLD or neuromuscular disease (NMD). METHODS: This was a quasi-experimental study involving children and adolescents with CLD or NMD. Before and after 6 months of home-based RMT, we measured respiratory muscle strength (MIP and MEP), PEF, and peak cough flow (PCF). We made statistical comparisons between the pre-RMT and post-RMT values, as well as evaluating the correlation between the duration and effect of RMT. RESULTS: The study included 29 patients, with a mean age of 12 years (range, 5-17 years), of whom 18 (62.1%) were male. The CLD group comprised 11 patients (37.9%), and the NMD group comprised 18 (62.1%). The mean duration of the RMT was 60 weeks (range, 46-90 weeks) in the CLD group and 39 weeks (range, 24-89 weeks) in the NMD group. In comparison with the pre-RMT values, the post-RMT values for MIP and MEP were significantly higher in both groups, whereas those for PEF and PCF were significantly higher only in the NMD group. We found no correlation between the duration and the effect of RMT. CONCLUSIONS: Home-based RMT appears to be an effective strategy for increasing respiratory muscle strength in children and adolescents with CLD or NMD, although it increased the ability to cough effectively only in those with NMD.
