Physics of Stress Measurements
2010Stresses cannot be measured directly. Stress determination is made indirectly, e.g. by the measurement of strain. Deformation values obtained from an unbalanced body approaching equilibrium in combination with theoretical knowledge about constitutive behaviour (stress-strain relationship) allows us to evaluate the state of stress existing in any ...

Physical Fitness: A Buffer against Stress
Perceptual and Motor Skills, 1986The purpose of this study was to determine the extent to which physically fit and unfit persons differ regarding levels of stress in their lives. The six Kraus-Weber tests were employed to assess minimal muscular function and fitness among 4,628 adult males, and a 10-item Likert-type inventory was administered to measure perceived stress.

The electrocardiogram during emotional and physical stress
International Journal of Psychophysiology, 1985The electrocardiographic response pattern during exercise at low and high heart rate was compared with the response pattern during emotional stress. Qualitative differences between exercise and emotional stress were obtained, i.e. during exercise the ST segment was more depressed, T-wave amplitudes were larger and QT and PQ were significantly shorter ...

[Physical factors and stress].
Meditsina truda i promyshlennaia ekologiia, 2002Physical factors of occupational environment and surroundings (noise, vibration, non-ionizing electromagnetic radiation, microclimate, etc) frequently could be considered stressing hazards, as cause marked functional changes in cardiovascular and nervous systems, in hematologic, immune and cytochemical values.

1984
The aim of this paper is to present a hypothesis to explain why stress, when prolonged for extended periods of time, or in a situation of sudden stress overload, causes a relatively local patho-physiological disease state which varies from individual to individual.

On the Significance of Magnesium in Extreme Physical Stress
Cardiovascular Drugs and Therapy, 1998In a double-blind randomized study, 23 competitive triathletes competing in an event consisting of a 500-meter swim, a 20-km bicycle race, and a 5-km run were studied after 4-week supplementation with placebo or 17 mmol/d Mg orotate. The tests were carried out without a break.

Speech - a possible indicator of physical stress
ICASSP '76. IEEE International Conference on Acoustics, Speech, and Signal Processing, 1976Summary form only given, as follows. In the recent years, considerable effort has been expended in determining a quantitative measure of fatigue, and various attempts to correlate psycilological measures with fatigue have not been successful. In this paper, a positive correlation between quantitative characteristics of speech data and fatigue measures ...

Physical impairment, stress, and cardiovascular disorders
International Rehabilitation Medicine, 1984Physical impairments bring about social and psychological consequences leading to stress. Here Dutch epidemiological data were used to test whether the physically disabled have an increased risk of CD. Results indicated this was partly so. Possible confounding variables, however, severely limit a firm statement concerning the relationship between ...

Environmental and physical stress and nutrient requirements
The American Journal of Clinical Nutrition, 1995When faced with hot, cold, or high-altitude environments, humans can either modify the microenvironment to fit human physiology, adapt their physiology to fit the environment, or use a combination of these two tactics. Metabolic adaptations to heat, cold, and high-altitude exposure may, in some instances, be accompanied by changes in nutrient ...

The physical and psychological stresses of women in firefighting
WORK: A Journal of Prevention, Assessment & Rehabilitation, 2000This literature review investigates females in the male-dominated field of firefighting. Various psychological and physical stressors are identified which are unique to women in this occupation. Psychological stressors include: self-doubt, skepticism of their abilities by others, performance pressure, sexual harassment, and social ostracism.
