Myocardial Infarction Associated With Physical Exertion in a Young Man

Circulation, 1997
A 20-year-old man was admitted to an outside institution with chest pain, shortness of breath, and a syncopal episode. He had previously been in good health until 2.5 years earlier, when he developed presyncope associated with chest pain and shortness of breath during an army training exercise.

Influence of Physical Exertion on Mental Performance with Reference to Training

Perceptual and Motor Skills, 1991
The aim of this study was to assess the effect of physical exertion (treadmill) on mental performance (matching a comparison design). Nine pairs of monozygotic twins (boys aged 11 to 14 yr.) were randomly divided into two groups, one trained and one untrained, while eight boys of the same age served as a control group.

Influence of warm-up duration on perceived exertion and subsequent physical performance of soccer players

Biology of Sport, 2019
The aim of this study was to analyse the effects of three warm-up protocols with different durations in semiprofessional soccer players. Fifteen semi-professional soccer players performed three warm-up protocols (Wup25min: 25 min, Wup15min: 15 min and ...

Physical Exertion as a Trigger of Acute Myocardial Infarction

New England Journal of Medicine, 1993
Background It is controversial whether the onset of myocardial infarction occurs randomly or is precipitated by identifiable stimuli. Previous studies have suggested a higher risk of cardiac events in association with exertion. Methods Consecutive patients with acute myocardial infarction were identified by recording all admissions to our hospital in ...

ATP and muscle enzyme efflux after physical exertion

Clinica Chimica Acta, 1975
Abstract Direct efflux of muscle enzymes into the blood stream was demonstrated in cats after physical exertion. Efflux occurred only after indications of marked depletion of adenosine triphosphate (ATP), consistent with earlier evidence that enzyme protein retention appears to depend on adequate intracellular ATP.

Using Ratings of Perceived Exertion in Physical Education

Journal of Physical Education, Recreation & Dance, 2013
Ratings of perceived exertion have been shown to be a valid method of monitoring physical activity intensity for both adults and children. As such, this subjective method may serve as an alternative to objective measurements for assessing students' performance on national standards 2 and 4.

The Effect of Physical Conditioning on Cardiac Response to Acute Exertion

Canadian Journal of Physiology and Pharmacology, 1974
The effect of chronic exercise (training) and acute exertion on myocardial water and electrolyte metabolism, Na–K-ATPase activity, and morphology was studied in the male rat. Training increased the potassium content in myocardial cells, the effect depending on the duration of the training period.

EXCESSIVE PHYSICAL EXERTION AND ITS EFFECT ON THE KIDNEYS

Journal of the American Medical Association, 1939
The kidney is an organ of secretion and excretion that can carry a heavy load over a short period even while temporarily deranged from normal because of this extra load placed on it and yet has a most emphatic power of reconstruction and early return to normal when this load has been removed.
