Physical Fitness: A Buffer against Stress

Perceptual and Motor Skills, 1986
The 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.

Stressful life events and physical health

Current Opinion in Psychiatry, 2006
This review summarizes the findings of recent researches from selected empirical and nonempirical publications focused on stressful life events and physical health.The findings can be divided into biological, psychological, and social issues concerning the important relationship between stressful life events and physical health. Growing evidence in the

Power Motivation, Stress and Physical Illness

Journal of Human Stress, 1980
College students reporting a large number of life change events in the past six months also reported significantly more frequent and more severe instances of physical illness and more affective symptoms in the same time period. These relationships, however, were modified in an interesting way by type of life change and by individual differences.

Physics of Stress Measurements

2010
Stresses 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 ...

Physics of Stressed Solids

The Journal of Chemical Physics, 1940
The internal energy of a system is subdivided into a work or potential function and a thermal or kinetic function, the former expressed in terms of the current electrostatic theory of intercrystalline bonding, and these functions then examined for variations of temperature, hydrostatic pressure, unidirectional stress and combined hydrostatic and ...

Physical Countermeasures to Stress

2011
Since the beginning of manned spaceflight, the challenge for space science is to avoid or minimize physiological degeneration processes of the musculoskeletal and cardiovascular system caused by missing gravity. With ongoing mission it became clear that weightlessness and isolation in space has an impact also on cognitive performance and mood.

Tissue Adaptation to Physical Stress: A Proposed “Physical Stress Theory” to Guide Physical Therapist Practice, Education, and Research

Physical Therapy, 2002
AbstractThe purpose of this perspective is to present a general theory—the Physical Stress Theory (PST). The basic premise of the PST is that changes in the relative level of physical stress cause a predictable adaptive response in all biological tissue.

Oxidative stress in biological systems and its relation with pathophysiological functions: the effect of physical activity on cellular redox homeostasis

Free radical research, 2019
The body of evidence from the past three decades demonstrates that oxidative stress can be involved in several diseases. This study aims to summarise the current state of knowledge on the association between oxidative stress and the pathogenesis of some ...

[Physical factors and stress].

Meditsina truda i promyshlennaia ekologiia, 2002
Physical 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.

Physical impairment, stress, and cardiovascular disorders

International Rehabilitation Medicine, 1984
Physical 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 ...
