Abstract. [Purpose] This study investigated functional capacity, physical activity, and respiratory and peripheral muscle strength in different functional classes of pulmonary arterial hypertension (PAH) compared with healthy subjects. [Subjects and Methods] This study included 31 patients with class II (n = 16) or class III (n = 15) PAH, classified according to the World Health Organization. Fifteen healthy subjects served as controls. Functional capacity was assessed using the 6-minute walk test (6MWT). Physical activity was determined using the International Physical Activity Questionnaire Short Form (IPAQ-SF). Respiratory muscle strength was measured using a mouth pressure device. Peripheral muscle strength was evaluated using a dynamometer.[Results] The 3 groups had similar demographic variables (p > 0.05). There were significant differences in 6MWT distance, maximal inspiratory pressure, and IPAQ categorical classification between the 3 groups (p < 0.05). Maximal expiratory pressure; total IPAQ score; and knee extensor, shoulder abductor, and hand grip strength were significantly lower in PAH patients (classes II and III) than in healthy subjects (p < 0.05).[Conclusion] As PAH progresses, respiratory muscle strength, functional exercise capacity, and physical activity decrease. Functional class should be taken into consideration when planning rehabilitation programs for this patient group.

“…This compares well with a study which showed a strong negative correlation between PEmax and the time spent in the rowing ergometer machine. 33 This study also suggested that EMS is associated more with exercise performance than IMS. In contrast, some studies have suggested that even with an increase in RMS no change has been observed in exercise performance especially in athletes or cyclists.…”

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.

[Purpose] To compare the effects of two physiotherapy protocols for chronic kidney disease patients on dialysis. [Subjects and Methods] This is a prospective, randomized study, in chronic kidney disease patients 18 years of age or older on dialysis. Sessions for each group (were conducted three times per week for a total of 10 sessions), during hemodialysis. Respiratory muscle strength (maximal inspiratory and expiratory pressure), peak expiratory flow, and peripheral muscle strength were evaluated. The study group received motor and respiratory physiotherapy, and the control group received motor physiotherapy alone. [Results] We observed a significant increase in the maximal inspiratory pressure in the study group in the 5th and 10th sessions and in the maximal expiratory pressure in the 1st session, peak flow in the 1st and 10th sessions, and dynamometry in the 10th session. In the control group, there was a significant decrease in maximal inspiratory pressure in the 5th and 10th sessions, and in maximal expiratory pressure in the 10th session, peak flow in the 5th and 10th sessions, and dynamometry in the 5th session. [Conclusion] Implementation of motor physiotherapy combined with respiratory physiotherapy may have contributed to the improvement of the variables analyzed in the study group.
