Filter by:Aim of this prospective, observational, multi-centered, randomized study is to detect cardiovascular complications in patients after coronavirus infection. The study will include 100 patients who underwent confirmed by laboratory tests COVID-19 infection (polymerase chain reaction (PCR) testing, enzyme-linked immunosorbent assay (positive result at least 1 time)) 1-3 months ago with the degree of lung lesion more than 25%, who were admitted to the University Clinical Hospital No. 4 of I.M. Sechenov First Moscow State Medical University. The study consists of 4 periods: 1. Screening for up to 6 months. 2. Inclusion in the study, undergoing of identical laboratory and instrumental testing. 3. Re-examination of patients. After 6 months from the initial examination (9 months after discharge from the infectious diseases department), patients will be re-examined. 4 Determination of end points, statistical data processing. Estimated result of the study is to confirm or refute the hypothesis: 1. As a result of the analysis of ECG and pulse wave data and comparison with echocardiography data, identify cardiovascular complications of COVID-19 infection. 2. To determine the diagnostic significance of pulse wave parameters for assessing cardiovascular complications in patients with a history of COVID-19 infection (sensitivity, specificity, positive and negative predictive value). 3. Identify correlations between pulse wave parameters and biochemical markers of endothelial dysfunction (endothelin-1). 4. As a result of the analysis of exhaled air by the proton mass spectrometry, to identify markers of cardiovascular complications in patients after COVID-19 infection. 5. As a result of a cardiorespiratory stress test, determine the respiratory and cardiovascular causes of dyspnea, exercise tolerance of patients after infection with COVID-19.
The main aim is to determine whether a gait retraining intervention will improve the strength of the foot-ankle muscle, the running economy and reduce the injury incidence in a one-year follow-up study. The secondary aim is to seek whether a minimal foot-ankle strength is necessary to reduce the risk to sustain to a running-related-injury to transit toward a forefoot strike pattern or toward a minimalist footwear for an endurance runner. Participants will be assessed at baseline, at 2 month follow-up, at 6 month follow-up and at 12 month follow-up. Assessment will be composed by questionnaires, a foot screening, maximal voluntary isometric strength of foot-ankle muscle with hand held dynamometer. Then, participants will run on a treadmill at self-paced and at 10 km/h with to measure their running economy and their footstrike pattern. In function of their distribution, participants will receive either nothing (control group) or minimalist footwear or a training to modify their footstrike pattern toward a more forefoot strike.
The competitive swimming and open water swimming events are scheduled for the 2024 Paris Olympic and Paralympian Games. Generally associated with a non-neglectable number of medals in the last Olympics, swimming performance depends on the swimmer's ability to manage his or her Stroke Length and Stroke Rate, where Velocity can be defined as the product of SR and SL. The optimisation of this management depends on the swimmer's ability to develop a large motor repertoire and to use the coordination mode (catch-up, opposition, superposition) best suited to the environmental constraints and opponents' adversity. These adaptations may contribute to 1) a modification of the energy expenditure or be dependent on the energy supply necessary for muscular contraction and 2) the preferential use of one or other of the metabolic pathways in the production of this chemical energy, moreover in an aquatic environment inducing particular thermal exchanges.
