Exercise Capacity

Dietary patterns and physical inactivity common in Western societies have been associated with chronic low-grade inflammation and an increased risk of non-communicable health conditions. Fruits and vegetables contain polyphenols and other bioactive compounds that may have antioxidant and anti-inflammatory properties and may influence inflammatory biomarkers. This study will evaluate the effects of increased consumption of a fruit juice on inflammatory biomarkers and exercise capacity in adults with mildly elevated inflammation. Approximately 40 participants will be randomly assigned to consume one of two fruit juice interventions daily for approximately 2 weeks. Changes in C-reactive protein (CRP) and exercise capacity, assessed using a 6-minute walk test, will be evaluated before and after the intervention and compared between the two groups.

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.

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.

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.

(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 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.
