BACKGROUND Mitral regurgitation during diastole in 5 subjects, of whom 4 affected by cardiovascular disease and 1 healthy competitive athlete, was the aim of this work. The 4 patients are respectively affected by: 1st case: arterial hypertension, dyslipidemia and III degree AV block in NYHA class II heart failure (HF); 2nd case: NYHA III HF, prosthetic biologic aortic valve dysfunction; 3th cas...

Treadmill tests for maximal oxygen uptake (V̇O2max) have traditionally used set speed and incline increments regardless of participants training or exercise background. The aim of this study was to determine the validity of a novel athlete-led protocol for determining maximal aerobic fitness in adults. Twenty-nine participants (21 male, 8 female, age 29.8 ± 9.5 y, BMI 24.4 ± 3.1, mean ± SD) from...

Since the passage of Title IX in 1972, female sports participation has dramatically increased.

Data on physiological effects and potential risks of a ultraendurance swimming are scarce. This report presents the unique case of a 61-year old athlete who completed a non-stop open-water 120-km ultramarathon swim on the Warta River, Poland. Pre-swimming examinations revealed favorable conditions (blood pressure, 110/70 mmHg; rest heart rate, 54 beats/minute, ejection fraction, 60%, 20.2 metab...

Changes intraventricular conduction and early ventricular repolarization observed during training are not always confirmed literature. We test healthy people look irregularities their ECG records. The study aims to draw attention ST-Elevation (STE) as a variant of White Athlete's...
