Fatigue and Skeletal Muscle Impact in Severe Axial Spondyloarthritis

Axial spondyloarthropathy (SpA) is the most common inflammatory rheumatism (1% of the general population) with important medico-economic consequences. Fatigue is a major feature of SA. It can be defined as a feeling of reduced muscle capacity, lack of energy and exhaustion. The fatigue reaches an abnormally high level (fatigue severity score (FSS) ≥4, called severe fatigue in this protocol) in more than two thirds of patients with SA. Skeletal muscle repercussions are present during SA. It is characterized by a decrease in exercise capacity independently of pain and ankylosis but is associated with a decrease in strength and muscle mass, the importance of which varies from one study to another. The link between fatigue (subjective sensation) and the skeletal muscular impact (objective) of SA has never been studied.

Short-Term Metformin Use in Young, Healthy Adults: Impacts on Exercise Capacity

Metformin is the most prescribed blood sugar (glucose)-lowering medication for patients diagnosed with type 2 diabetes mellitus (T2DM). Metformin stimulates glucose uptake in skeletal muscle similar to the effects of exercise, though, some studies report that metformin may decrease exercise capacity. The main question this study looks to answer is: • Does metformin alter exercise capacity? Participants will: * Complete 5 exercise tests on a stationary bike. * Undergo a body composition test. * Take metformin and placebo. * Complete food and symptom logs. The researchers hypothesize that: • Metformin will reduce aerobic capacity.

Health-Related Physical Fitness Level From Smartwatches

Health-related physical fitness (HRPF) has demonstrated high clinical relevance, and its level is associated with the ability to perform activities of daily living with vigor and a lower risk of chronic disease. Consequently, exercise prescription guidelines recommend improving HRPF as a focus for prevention and rehabilitation programs. Measuring and tracking HRPF often requires specialized equipment and personnel, which are expensive and less applicable to the general population. Wearables may mitigate this issue by providing useful estimates of the HRPF.

Exercise Capacity, Muscle Oxygenation, and Physical Activity Between Patients With Interstitial Lung Disease

Interstitial lung diseases (ILD) are a group of chronic respiratory diseases that cause significant mortality and morbidity worldwide. Although there are studies in the literature comparing different lung disease groups with healthy individuals, it has been determined that there is no study comparing the exercise capacity, muscle oxygenation, physical activity level, respiratory functions, respiratory and peripheral muscle strength, inspiratory muscle endurance, quality of life and sleep quality of individuals diagnosed with ILD with healthy individuals.

Validity and Reliability of 6-minute Pegboard and Ring Test in Patients With Interstitial Lung Disease

Interstitial lung diseases (ILD) are a heterogeneous group of chronic respiratory diseases that cause significant mortality and morbidity worldwide, characterized by diffuse inflammation in the lung parenchyma and vascular structures, can progress to fibrosis, have known or unknown etiology, and can develop secondary to systemic autoimmune connective tissue diseases other than diseases where the primary pathology is in the lung. The 6-minute peg-board and ring test, which was first developed to determine the upper extremity exercise capacity of chronic obstructive pulmonary disease patients, is an exercise test used to evaluate upper extremity functional exercise capacity in different lung diseases. It has been determined that there is no study on the validity and reliability of this test in individuals with ILD.

Lung Function, Exercise Capacity, and Serology Responses in Patients With COVID-19

(a) Objectives 1. To assess the full lung function, exercise capacity, quality of life in patients with COVID-19 over 2 years. 2. To assess the longevity of the serology response to SARS-CoV2. 3. To investigate the association of the neutralization titer in plasma from different vaccinated cohorts to its protection of infection using in vivo model 4. To investigate the SARS-CoV-2 specific cellular and humoral immunities as well as their determinant factors from community subjects who have received different types of COVID-19 vaccines. 5. To assess the third booster dose for subjects who have poor antibody response despite having received two doses of CoronaVac (Sinovac)

Exercise Capacity in Diseases and Health

Exercise capacity is a key factor to evaluate and treat patients in different diseases (e.g. ischemic heart disease, chronic obstructive pulmonary disease, cystic fibrosis). The best way to measure exercise capacity is to perform a cardiopulmonary exercise testing. Normal/reference values in health and disease relate to specific population and subpopulations. The population in Israel is unique in its diversity. Objectives: Data collection of exercise capacity assessment in health and illness in the northern of Israel for future local database. Population: 500 Patients evaluated routinely in the exercise lab (pediatric cardiology institute) and healthy volunteers evaluated as controls. Study design: Prospective observational study. Participants will answer a health related questioner, undergo a physical examination, perform a cardiopulmonary exercise test on a treadmill or a cycle ergometer.
