Physical activity plays a key role in the control of neuroendocrine, autonomic, and behavioral responses to physical and psychosocial stress. However, little is known about how the level of physical activity modulates stress responsiveness. Here, we test whether different levels of physical activity are associated with different adrenal, cardiovascular, and psychological responses to psychosoci...

OBJECTIVE Psychosocial stress is a suggested risk for coronary heart disease (CHD). The relationship of stress resilience in adolescence with subsequent CHD risk is underinvestigated, so our objective was to assess this and investigate the possible mediating role of physical fitness. METHODS In this register-based study, 237,980 men born between 1952 and 1956 were followed from 1987 to 2010 u...

In this research, behaviour of clayey soils under triaxial loading is studied using Neural Network. The models have been prepared to predict the stress-strain behaviour of remolded clays under undrained condition. The advantage of the model developed is that simple parameters such as physical characteristics of soils like water content, fine content, Atterberg limits and so on, are used to mode...

background and purpose: hemodialysis patients face several physical and mental tension factors including depression, anxiety and stress, which could decrease their quality of life. this study aimed to identify the relationship between quality of life (qol), depression, anxiety and stress in patients undergoing hemodialysis. methods: this descriptive, analytical study was conducted on 160 hemodi...

Background Cardiac stress testing is the standard of care for diagnosing ischemic heart disease. Traditional stress testing involves physical or pharmacological stress to induce hyperemia and/or increase myocardial oxygen demand. Physical stress is not possible in 100% of cases however, and pharmacological stress carries rare but serious risk. We asked whether acute isocapnic hypoxia could be u...

stress, as an inevitable and indispensible reality of modern time, has a multitude of positive and negative effects on the physical and psychological health of man and survival and development of organizations. therefore, the precise and timely identification of stressors and a readiness to prevent and cope with them is a great task of men and organizations at the twenty- first century. with th...

abstract background: cancer is a broad group (over 270 types) of diseases. this disease, like other chronic diseases, occurs in all ages and ethnic groups, and is considered as a major health problem. stress is one of the most important psychological factors influencing the occurrence of physical diseases, and can lead to severe anxiety, depression, and negative effects on health. it can also m...

Stress can be defined as a state of increased psychological, physiological and behaviourial preparedness. A stress reaction is a normal reaction that is considered necessary rather than harmful. Physical activity is generally deemed a stress factor that activates our physiological stress systems in the same way as exposure to psychological stress. The following chapter describes acute stress re...
