Abstract Funding Acknowledgements Type of funding sources: None. Background Heart transplantation (HTX) is a therapeutic option in a selected group of patients with end-stage heart failure. Although cardiac function normalizes after surgery, maximal exercise capacity of HTX-patients after 1 year is only half that of age- and gender matched healthy subjects. Data on the evolution of muscle strength and physical activity after HTX are scant. Having this knowledge might help to optimize rehabilitation programs. Purpose To describe changes in muscle strength and physical activity following HTX. Methods 58 HTX-patients were addressed, of whom 52 (90%) patients participated in the study. Study visits were planned every 3 months from hospital discharge until 1 year of follow-up. 43 HTX-patients (67% male; age: 48 ± 14 years; BMI: 24 ± 4 kg/m²) fulfilled the study protocol. Outcome measures included functional exercise capacity (6MWD), peripheral strength (QF), respiratory muscle strength (MIP) and objectively measured physical activity (PAwalk, walking intensity (WI), PAsteps). All patients received physiotherapy at home during the first 6 weeks, as standard of care after thoracic surgery. After that, cardiac rehabilitation in a specialized center was started. Data were analyzed using repeated measures ANOVA, with Bonferroni test as post-hoc test. Results 6MWD (+178 ± 17 meter), QF (+26 ± 4 Nm) and MIP (-32 ± 3 cmH2O) significantly improved over time (p < 0.0001). Despite improvements in QF, peripheral muscle weakness was still present in 32% of patients 1 year post-HTX. A significant time effect in PA (PAwalk (+33 ± 7 minutes/day), WI (+0.036 ± 0.007 g) and PAsteps (+3711 ± 640 steps/day)) could be noticed (p < 0.0001). Sedentary time did not significantly change during follow-up (p = 0.14). (Figure 1) Conclusion Functional exercise capacity and muscle strength gradually improve during 1 year after HTX. A considerable number of patients still present with peripheral muscle weakness. Despite improvements in PA, results remain below recommended health levels. Enrollment in a cardiac rehabilitation program, offering a combined exercise and PA intervention seems warranted to further enhance health outcomes in this patient population. Abstract Figure 1

Objective We aimed to compare functional exercise capacity, respiratory and peripheral muscle strength, pulmonary function and quality of life between patients with stable angina and healthy controls. Methods We compared 33 patients with stable angina (55.21 ± 6.12 years old, Canada Class II–III, left ventricular ejection fraction: 61.92 ± 7.55) and 30 healthy controls (52.70 ± 4.22 years old). Functional capacity (6-minute walk test (6-MWT)), respiratory muscle strength (mouth pressure device), peripheral muscle strength (dynamometer), pulmonary function (spirometer) and quality of life (Short Form 36 (SF-36)) were evaluated. Results 6-MWT distance (499.20 ± 51.91 m versus 633.05 ± 57.62 m), maximal inspiratory pressure (85.42 ± 20.52 cmH2O versus 110.44 ± 32.95 cmH2O), maximal expiratory pressure (83.33 ± 19.05 cmH2O versus 147.96 ± 54.80 cmH2O) and peripheral muscle strength, pulmonary function and SF-36 sub-scores were lower in the angina group versus the healthy controls, respectively. Conclusion Impaired peripheral and respiratory muscle strength, reduction in exercise capacity and quality of life are obvious in patients with stable angina. Therefore, these parameters should be considered in stable angina physiotherapy programmes to improve impairments.

Functional Exercise Capacity

BackgroundExercise capacity, muscle function, and physical activity levels remain reduced in recipients of lung transplantation. Factors associated with this deficiency in functional exercise capacity have not been studied longitudinally.ObjectiveThe study aims were to analyze the longitudinal change in 6-minute walking distance and to identify factors contributing to this change.DesignThis was a longitudinal historical cohort study.MethodsData from patients who received a lung transplantation between March 2003 and March 2013 were analyzed for the change in 6-minute walking distance and contributing factors at screening, discharge, and 6 and 12 months after transplantation. Linear mixed-model and logistic regression analyses were performed with data on characteristics of patients, diagnosis, waiting list time, length of hospital stay, rejection, lung function, and peripheral muscle strength.ResultsData from 108 recipients were included. Factors predicting 6-minute walking distance were measurement moment, diagnosis, sex, quadriceps muscle and grip strength, forced expiratory volume in 1 second (percentage of predicted), and length of hospital stay. After transplantation, 6-minute walking distance increased considerably. This initial increase was not continued between 6 and 12 months. At 12 months after lung transplantation, 58.3% of recipients did not reach the cutoff point of 82% of the predicted 6-minute walking distance. Logistic regression demonstrated that discharge values for forced expiratory volume in 1 second and quadriceps or grip strength were predictive for reaching this criterion.LimitationsStudy limitations included lack of knowledge on the course of disease during the waiting list period, type and frequency of physical therapy after transplantation, and number of missing data points.ConclusionsPeripheral muscle strength predicted 6-minute walking distance; this finding suggests that quadriceps strength training should be included in physical training to increase functional exercise capacity. Attention should be paid to further increasing 6-minute walking distance between 6 and 12 months after transplantation.

Recreational Runners

Background: Running is a new trend of recreational sports in Indonesia. About 70% of recreational runners have difficulty in improving exercise capacity due to exercise-related transient abdominal pain (ETAP), caused by fatigue of the diaphragmatic muscles. Previous studies have shown that various training methods may increase diaphragmatic muscle strength and endurance, for example, inspiratory muscle training (IMT). Unfortunately, improvement of inspiratory muscle strength and endurance after exercise and IMT are still varies. Therefore, other methods are needed to optimize the effect of IMT. Application of the elastic taping on thoracic wall during exercise allows the inspiratory muscles to contract optimally which might improve functional capacity.Aim: To assess the effect of elastic taping on inspiratory muscle training using the pressure threshold IMT, in increasing the functional exercise capacity of recreational runners. Functional capacity was measured based on VO2max value, rating of perceived breathlessness (RPB) and rating of perceived exertion (RPE).Methods: an experimental study involved 14 nonsmoker recreational runners, ages 20-40 years, at Outpatient Clinic of Physical Medicine and Rehabilitation Department of Dr. Soetomo Hospital Surabaya. Subjects were divided into two groups (pressure threshold IMT with and without elastic taping groups), which were observed for four weeks. IMT was done five times a week, twice a day, with 30 repetitions, and 60% resistance 30 RM using Respironics®. Elastic taping Leukotape® was applied on the first until fifth day in each IMT sessions. The running exercises were done three times a week with EnMill® Treadmill ETB-03195 with a speed of 4.5 mph and 0% inclination. RBP, RPE and VO2max were measured using Borg Dyspneu scale, Borg Scale, and Bruce Treadmill Protocol test, respectively, before the first exercise and after 4 weeks of exercise.Results: There were an improvement of functional exercise capacity in both groups which were marked with a decline of RPB and RPE and increase of VO2max (p values < 0.05). However, there were no significant differences in the decrease of RPB and RPE and an increase of VO2max between groups (p values of were 0.31, 0.83, and 0.13, respectively). The effect of the elastic taping (r2 = 0.99) was not reflected in the differences of RPB, RPE and increasing VO2max.Conclusion: Inspiratory muscle training using pressure threshold IMT with or without the elastic taping for four weeks can improve exercise capacity of recreational runners.

Abstract Objective The purpose of this study was to investigate the effectiveness of elastic resistance training on improving muscle strength, functional exercise capacity, health-related quality of life (HRQoL), and dyspnea in people with stable chronic obstructive pulmonary disease (COPD). Methods For this systematic review, PubMed, The Cochrane Library, Embase (OVID), PEDro, SciELO, and CINAHL were searched from inception to November 2019. Included studies were randomized clinical trials in which people with stable COPD were allocated to (1) an experimental group that received lower-limb resistance training, upper-limb resistance training, or both using elastic resistance; or (2) a control group that received no or sham resistance training or conventional resistance training using weight machines. Data extraction was performed by 3 review authors. The methodological quality of the studies was assessed using the PEDro scale. Eight studies on 332 participants were included. Results Knee extensor strength was higher in the experimental group (standardized mean difference = 0.52, 95% CI = 0.09–0.95) compared with the non-exercise control group. Compared with the conventional exercise control, the experimental group presented similar effects for muscle strength, functional exercise capacity, HRQoL, and dyspnea (95% CI overlapped the line of no effect for all). Conclusions Elastic resistance training improves muscle strength in people with COPD. The current review suggests elastic resistance as a potential alternative to conventional resistance training using weight machines, as they show similar effects on muscle strength, functional exercise capacity, HRQoL, and dyspnea. Impact Due to its beneficial effects, including reduced risk of exacerbation-related hospitalizations, exercise training is viewed as the cornerstone of pulmonary rehabilitation in people with COPD. This study shows that elastic resistance training can be an effective, portable, practical, and low-cost alternative to conventional weight resistance training. Lay Summary Training with elastic resistance tubes or bands—which are easy to carry, easy to use, and relatively low cost—can be an effective way to improve strength for people with COPD and promote similar benefits to those achieved with weight machines.
