A French team handball player being ejected from a match, signaled by the red card held aloft by the referee. In sports, an ejection (also known as dismissal, sending-off, disqualification, or early shower) is the removal of a participant from a contest due to a violation of the sport's rules.
Sports medicine is a branch of medicine that deals with physical fitness and the treatment and prevention of injuries related to sports and exercise. Although most sports teams have employed team physicians for many years, it is only since the late 20th century that sports medicine emerged as a distinct field of health care.
Stroke volume is an important determinant of cardiac output, which is the product of stroke volume and heart rate, and is also used to calculate ejection fraction, which is stroke volume divided by end-diastolic volume. Because stroke volume decreases in certain conditions and disease states, stroke volume itself correlates with cardiac function.
Modalities applied to measurement of ejection fraction is an emerging field of medical mathematics and subsequent computational applications. The first common measurement method is echocardiography, [7] [8] although cardiac magnetic resonance imaging (MRI), [8] [9] cardiac computed tomography, [8] [9] ventriculography and nuclear medicine (gated SPECT and radionuclide angiography) [8] [10 ...
Ejection or Eject may refer to: Ejection (sports), the act of officially removing someone from a game; Eject (Transformers), a fictional character from The Transformers television series "Eject" (song), 1993 rap rock single by Senser; The usage of an Ejection seat by a pilot in an aircraft; Eject, a 2014 album by Cazzette
Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.
'Exercise is Medicine' is a trademarked non-profit venture of the American College of Sports Medicine. By comparison, 'Exercise Medicine' is a specific subspecialty of 'Sport and Exercise Medicine'. The concept of 'Exercise is Medicine' is that all medical specialists should be prescribing exercise regularly as an adjunct to a standard ...
Sports cardiology is an emerging subspecialty field of Cardiology. [1] [2] [3] It may also be considered a subspecialty field of Sports medicine (or Sport & Exercise Medicine), or alternatively a hybrid subspecialty that spans cardiology and sports medicine. Emergency medicine is another medical specialty that has some overlap with Sports ...
