The Effects of Physical Exertion on Cognitive Performance [PDF]
, 2002 Abstract : This study examined the cognitive and physiological performance of soldiers as they exercised on a treadmill at various grades. Twelve soldiers walked at 1.56 m/sec on three grades, 0%, 3.5%, and 7.0%. The cognitive tasks performed by the soldiers were taken from the Walter Reed Performance Assessment Battery. The tasks chosen for this study

Exercise, physical activity, and exertion over the business cycle [PDF]
Social Science & Medicine, 2013 Shifts in time and income constraints over economic expansions and contractions would be expected to affect individuals' behaviors. We explore the impact of the business cycle on individuals' exercise, time use, and total physical exertion, utilizing information on 112,000 individual records from the 2003-2010 American Time Use Surveys. In doing so, we

Physical aptitudes to exertion in children with Down's syndrome
Journal of Intellectual Disability Research, 1989ABSTRACT. The individual with Down's syndrome is characterized by apathy towards physical exercise. Ten untrained subjects with Down's syndrome and a control group have been tested at rest and after exercise on a bicycle ergometer. In subjects with Down's syndrome, the authors have observed: (a) a lower orthostatic index at rest; (b) a lower indirect ...

The physiology of extreme physical exertion
Endeavour, 1987Abstract Regular physical activity can make an important contribution to maintaining a healthy body. However, insufficient knowledge of the biological laws underlying the training process may easily lead to excessive strain and injuries. Extremely strenuous activities, such as marathons and triathlons, require proper training and preparation ...

Physical Exertion and Mental Performance
Ergonomics, 1973The problem of why people in a state of fatigue make wrong decisions prompted a series of laboratory experiments of which two are described. Subjects pedalled a bicycle ergometer for varying periods of time and were tested for mental performance after different amounts of physical exertion.

Reduction in Exertional Myoglobinemia After Physical Conditioning
Archives of Internal Medicine, 1979The development of a sensitive radioimmunoassay for the measurement of myoglobin now permits the accurate determination and detection of even small concentrations of serum myoglobin. To determine the effect of exercise and physical conditioning on serum myoglobin levels, 16 male Army recruits (ages 18 to 28 years) underwent treadmill exercise and ...

Perceived Exertion of Physical Activity During Pregnancy
Journal of Physical Activity and Health, 2015Background:Maternal physical activity declines across gestation, possibly due to changing perception of physical activity intensity. Our purpose was to a) determine whether rating of perceived exertion (RPE) during a treadmill exercise changes at a given energy expenditure, and b) identify the influence of prepregnancy physical activity behavior on ...

PHYSICAL EXERTION AS A RISK FACTOR FOR SPONTANEOUS ABORTION
Epidemiology, 1994This study examined the association of physical exertion and spontaneous abortion in a case-control study of 607 women whose pregnancies ended in spontaneous abortion and 1,287 women who delivered livebirths in Santa Clara County, CA, in 1986 and 1987. We interviewed women about the number of hours they spent doing heavy housework and caring for young ...
