Cardiorespiratory fitness (CRF) reflects the integrated ability to deliver oxygen from the atmosphere to the skeletal muscles and to utilize it to generate energy to support muscle activity during exercise. Peak oxygen uptake (V?O2) is internationally recognized as the criterion measure of youth CRF. It is well-documented that in youth peak V?O2 increases with sex-specific, concurrent changes in a range of age- and maturity status-driven morphological and physiological covariates with the timing and tempo of changes specific to individuals. However, a recent resurgence of interest in predicting peak V?O2 from field test performances and the persistence of fallacious interpretations of peak V?O2 in 1:1 ratio with body mass have obfuscated general understanding of the development of CRF. Moreover, as spurious relationships arise when ratio-scaled data are correlated with health-related variables the use of this scaling technique has confounded the relationship of youth CRF with indicators of current and future health. This paper reviews the extant evidence and concludes that the interpretation of youth CRF and the promotion of young people’s health and well-being should be founded on scientific facts and not on fictions based on flawed methodology and specious interpretation of data.

This investigation was made to evaluate the health and well-being of workers who made activities in the manufacturing processes of an aerospace industry installed in the city of Mexicali and based on the evidence presented in certain stages of a production line. The cost-benefit of applying ergonomic methods was analyzed, developing a descriptive model, which involved important aspects. Said aspects analyzed were (1) work methods, (2) training of employees in the operational area, (3) evaluation of times and movements of industrial operations, and (4) working conditions as the relationship of workers with supervisors and managers.

While dispositional mindfulness is a popular construct in the field of positive psychology, its nomological network in the context of health and well-being is not well established. Our study addresses this limitation by examining the relationship between dispositional mindfulness and various health-related psychological constructs, including personality, social well-being, and affective states. Data for this study were gathered from the national longitudinal studies of health and well-being called Midlife in the United States (MIDUS-II and MIDUS-III). The nomological network analysis of dispositional mindfulness showed positive associations with both religiosity and overall well-being measures (e.g., Social Well-Being, Sympathy, Optimism, and Generativity) and negative associations with maladaptive tendencies (e.g., Pessimism, Aggression, Neuroticism, and Personal Constraints). Finally, test-retest validity was positively verified by significant correlations among the variables, spanning over ten years. Articulating a nomological network of dispositional mindfulness has important implications for future research and practice.

Abstract Objective This study examines under which conditions being an observer of bullying can be detrimental to health and well-being. It was hypothesized that health-related problems following observations of bullying are determined by (1) whether the observer has been exposed to bullying her/himself and (2) whether the observer have tried to intervene in the bullying situation that they witnessed. Methods The study was based on a longitudinal probability survey of the Swedish workforce, with an 18-month time lag between assessment points (N = 1096). Results Witnessing bullying at work were associated with an increase in subsequent levels of mental distress among the observers, although this association became insignificant when adjusting for the observers’ own exposure to bullying. Intervening against bullying moderated the relationship between observations of bullying and mental health problems. Observers who did not try to intervene reported a significant increase in mental health problems at follow-up, whereas there were no significant changes in levels of mental health problems among those who did intervene. Conclusions the findings suggest that observer interventions against bullying may be highly beneficial for both the targets and observers of bullying. Organizations should therefore invest in ways to increase constructive bystander behavior in negative social situations at the workplace.

Few studies have looked at the relationship of job characteristics and worker well-being among Norwegian academics. The main purpose of this study was to examine the relationship between job demands, job resources, burnout, and engagement among Norwegian university staff. In total, 236 staff from one university in Norway answered the questionnaire. Hierarchical multiple regression analyses identified job demands as the most important predictors for burnout. Autonomy was the most important job resource in the prediction of engagement and burnout. What constitutes a job resource or a job demand varies from occupation to occupation. The present study adds to the existing literature by examining factors that may protect or harm the individual workers’ health and well-being in a Norwegian university context.

The late Dr. Fazlur Rahman, Harold H. Swift Distinguished Service Professor of Islamic Thought at the Oriental Institute of the University of Chicago, has written this book as number seven in the series on Health/Medicine and the Faith Traditions. This series has been sponsored as an interfaith program by The Park Ridge Center, an Institute for the study of health, faith, and ethics. Professor Rahman has stated that his study is "an attempt to portray the relationship of Islam as a system of faith and as a tradition to human health and health care: What value does Islam attach to human well-being-spiritual, mental, and physical-and what inspiration has it given Muslims to realize that value?" (xiii). Although he makes it quite clear that he has not attempted to write a history of medicine in Islam, readers will find considerable depth in his treatment of the historical development of medicine under the influence of Islamic traditions. The book begins with a general historical introduction to Islam, meant primarily for readers with limited background and understanding of Islam. Following the introduction are six chapters devoted to the concepts of wellness and illness in Islamic thought, the religious valuation of medicine in Islam, an overview of Prophetic Medicine, Islamic approaches to medical care and medical ethics, and the relationship of the concepts of birth, contraception, abortion, sexuality, and death to well-being in Islamic culture. The basis for Dr. Rahman's study rests on the explication of the concepts of well-being, illness, suffering, and destiny in the Islamic worldview. He describes Islam as a system of faith with strong traditions linking that faith with concepts of human health and systems for providing health care. He explains the value which Islam attaches to human spiritual, mental, and physical well-being. Aspects of spiritual medicine in the Islamic tradition are explained. The dietary Jaws and other orthodox restrictions are described as part of Prophetic Medicine. The religious valuation of medicine based on the Hadith is compared and contrasted with that found in the scientific medical tradition. The history of institutionalized medical care in the Islamic World is traced to awqaf, pious endowments used to support health services, hospices, mosques, and educational institutions. Dr. Rahman then describes the ...
