Stroke patients have reduced aerobic capacity. Therefore, intensive structured exercise programs are needed. We report the case of a patient with stroke and cardiac disease who underwent early inpatient cardiac rehabilitation (CR). A 38-year-old male patient with atrial fibrillation, heart failure, and cerebral infarction underwent a symptom-limited exercise tolerance test (ETT) without any problems on day 45 after admission. He completed a 2-week inpatient program and an 8-week home-based CR program. Follow-up ETT showed increased exercise capacity. The present case might be the first to report a safely performed CR program in a patient with stroke and cardiac comorbidity in Korea. Systematic guidance is needed for post-stroke patients to receive safe and effective CR for the secondary prevention of stroke and cardiovascular risk.

Background: Astragalus membranaceus is a well known oriental medicinal herb. The polysaccharides of the aboveground parts (AMA) and the radix (AMR) of A. membranaceus are the most important functional constituents. Methods and Results: The aim of this study was to determine the effects of AMA and AMR on the oxidative damage induced in the skeletal muscle of rats subjected to exhaustive exercise. Sprague-Dawley rats were randomly divided into exercise and non-exercise groups; in the groups receiving the test compounds, AMA and AMR were administered orally for 30 days. Skeletal muscle samples were collected from each rat after running to exhaustion on a treadmill to determine the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) and the concentation of malondialdehyde (MDA). The antioxidant enzyme activities of SOD and GSH-Px of skeletal muscle of AMA- and AMR-treated groups were significantly higher than those of the control and commercial sports drink (SPD)-treated groups in exhaustive exercise rats. In addition, MDA concentrations in the skeletal muscle of the AMA- and AMR-treated groups were significantly lower than those of the control and SPD-treated groups. In the present study, the effects of AMA and AMR on exercise endurance capacity were also evaluated in mice subjected to a swimming exercise test. AMA and AMR supplementation prolonged the swimming time of mice and enhanced exercise endurance capacity. AMA and AMR possess the ability to retard and lower the production of blood lactate, and prevent the decrease of serum blood glucose. Conclusions: These results showed that, AMR and AMA exerted beneficial effect in mice, increasing the activity of the antioxidant systems and inhibiting oxidative stress induced by exhaustive exercise. The compounds improved exercise performance and showed anti-fatigue effects against exhaustive exercise.

Purpose : People who have suffered from COVID-19 suffer from decreased pulmonary function and various side effects. This study aims to present three respiratory exercise intervention methods to improve pulmonary function in COVID-19 survivors. Therefore, the purpose of this study will investigate the effects of breathing exercise interventions (aerobic exercise, diaphragm breathe exercise, and inspiratory muscle training on resistance) on pulmonary function in COVID-19 survivors. Methods : The subjects who participated in this study were 35 male and female college students confirmed with COVID-19. All subjects were randomly assigned to A, D, and I groups according to breathing exercise intervention method. Groups A, D, and I each performed aerobic exercise, diaphragm breathing exercise, and inspiratory muscle training on resistance, 3 times a week for 6 weeks. Pulmonary function was measured using a spirometer, and FVC (forced vital capacity), FEV₁ (forced expiratory volume in one second), FEV₁/FVC % (forced expiratory volume in one second / forced vital capacity ratio), and PEF (peak expiratory flow) were measured at 0, 3, and 6 weeks. Data analysis was compared by repeated measures analysis of variance, and post hoc tests for time were compared and analyzed using paired t-tests. Results : In the results of this study, FVC values showed statistically significant improvement in all groups. FEV₁ values also showed statistically significant improvement in all groups. And the FEV₁/FVC % value also showed statistically significant improvement in all groups. And the PEF values also showed statistically significant improvement in all groups. Conclusion : The results of this study reported that aerobic exercise, diaphragm breathing exercise, and resistance inspiratory muscle training were all effective in improving pulmonary function in COVID-19 survivors. Therefore, application of the three breathing exercise intervention methods presented in this study will help improve pulmonary function in COVID-19 survivors.
