These alterations vary in type, can be eccentric or concentric, depending on the nature of exercise. Speckle tracking echocardiography (<jats:styled-content style=\"fixed-case\">STE<\/jats:styled-content>) is a novel, angle\u2010independent method that accurately and reliably measures systolic and diastolic functions of the left ventricle (<jats:styled-content style=\"fixed-case\">LV<\/jats:styled-content>) with considerably lower inter\u2010operator variability.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and Results<\/jats:title><jats:p>Twenty\u2010two marathon runners, 24 wrestlers, and 20 healthy sedentary individuals were included in the study.
