Background: Chronic Obstructive Pulmonary Disease (COPD) is a common respiratory disease that significantly impairs the quality of life of patients. Single exercises can help COPD patients focus on enhancing specific physical abilities, and enable a more precise analysis of the specific effects of single exercises on improving exercise capacity in COPD patients.
Objectives: To evaluate the effectiveness of single exercises in improving the exercise capacity of COPD patients and to conduct an indirect comparison to identify the most efficacious intervention.
Methods: We conducted a comprehensive search for randomized controlled trials in the following databases: PubMed, Web of Science, Scopus, Cochrane Library, Embase, and Chinese National Knowledge Infrastructure, from their inception to July 1, 2024. A network meta-analysis was used. We calculated mean differences and their corresponding 95% confidence intervals to quantify the effect sizes and assess the precision of the estimates.
Results: 65 studies that met the inclusion criteria, encompassing a total sample size of 5,034 participants. The meta-analysis demonstrated that single exercises significantly enhanced the exercise capacity in COPD patients. Upon direct comparison, several exercises showed significant improvements in exercise capacity compare to conventional therapy. Core muscle Elastic band exercise appeared to provide the most substantial benefit in enhancing exercise capacity in COPD patients.
Conclusion: Healthcare providers are encouraged to consider incorporating Core muscle Elastic band exercise into their intervention plans, given its demonstrated efficacy. However, the presence of substantial heterogeneity among the included studies highlights the need for caution in interpreting these results.

Exercise capacity and the psychosocial effect in preterm born infants - Should we do more?

Physical activity is crucial for children's physical, cognitive, and social development, reducing the risk of non-communicable diseases and improving overall well-being. A major legacy of extremely preterm delivery is respiratory limitation with reduced lung function and decreased exercise capacity which can be further exacerbated by inactivity and deconditioning. Strategies to increase incidental physical activities in early childhood and participation in sport and more formal exercise programmes in middle childhood have the potential to optimize cardiopulmonary function, improve quality of life, and foster social interactions in childhood and beyond, thereby providing benefits that extend far beyond the physical domain.

Introduction: Patients with peripheral artery disease (PAD) can experience intermittent claudication, which limits walking capacity and the ability to undertake daily activities. While exercise therapy is an established way to improve walking capacity in people with PAD, it is not feasible in all patients. Neuromuscular electrical stimulation (NMES) provides a way to passively induce repeated muscle contractions and has been widely used as a therapy for chronic conditions that limit functional capacity.

Objective: This study aimed to evaluate the effects of different cold acclimation strategies on exercise performance in male mice exposed to low-temperature environments.
Methods: Male mice were subjected to five distinct acclimation regimens over 8 weeks: immersion at 10 °C (10 °CI) or 20 °C (20 °CI), swimming at 10 °C (10 °CS), 20 °C (20 °CS), or 34 °C (34 °CS). During the first 2 weeks, the acclimation time progressively decreased from 30 min to 3 min per day, and the water temperatures were lowered from 34 °C to the target levels, followed by 6 weeks of consistent exposure.

Effects of Quercetin and Citrulline on Nitric Oxide Metabolites and Antioxidant Biomarkers in Trained Cyclists.

Department of Public Health & Exercise Science, Appalachian State University, Boone, NC 28607, USA.
Background: Quercetin (QCT) and citrulline (CIT) have been independently associated with improved antioxidant capacity and nitric oxide (NO) production, potentially enhancing cardiovascular function and exercise performance. This study aimed to evaluate the combined and independent effects of QCT and CIT supplementation on NO metabolites and antioxidant biomarkers in 50 trained cyclists undergoing a 20 km cycling time trial (TT).
Methods: In a randomized, double-blind, placebo-controlled design, forty-two male and eight female trained cyclists were assigned to QCT + CIT, QCT, CIT, or placebo (PL) groups.
