OBJECTIVES To examine whether well-known predictors of mortality change their predictive power over time, being reduced or even reversed in the old-old. DESIGN A multidimensional survey of the Cross-Sectional and Longitudinal Aging Study conducted from 1989 to 1992 with follow-up of mortality after 6, 8, 10, and 12 years since 1989. SETTING Israel. PARTICIPANTS Participants (N=1,369) were...

In this article, the authors propose an original analysis of the cardiac frequency after training. The study of rapid diminution (alactic oxygen debt) and of plateau (lactic debt in oxygen) make possible adjustment of the training. The variations observed in young swimmers during their sporting season and note a tangible improvement of the two components for recovery.

How different this seems from the desolate and malaria-ridden country widely portrayed by nineteenthand early twentieth-century visitors in the region, before the modern agricultural revolution changed the face of the landscape. At another time I hope to deal at length with the matter of cultivation in the Emathian plain in antiquity. At present, however, it may be useful to attempt to understa...

Frailty is a multifaceted condition that affects many older adults and marks decline on areas such as cognition, physical condition, and nutritional status. Frail individuals are at increased risk for the development of disability, dementia, and falls. There are hardly any health services that enable the identification of prefrail individuals and that focus on prevention of further functional d...

Taylor and Lobel's (1989) model of social comparison processes under threat predicts that upward affiliation (a social activity) may be useful to improve the skills and to find inspiration in coping with HIV, whereas downward evaluation (a cognitive activity) may assist someone to feel better by comparing oneself to a less fortunate person. Participants with HIV were randomly assigned, using a ...

Until recently, the constraints imposed on decision makers by the human physical condition - situated both as a physical agent and within physical space - have played only an incidental, if not entirely inconsequential, role in conceptualizations of human decision making. The act of deciding has been positioned as the quintessence of traditional decision theory, while actual enactment of the de...

In long-lived vertebrates, individuals generally visit potential breeding areas or populations during one or more seasons before reproducing for the first time. During these years of prospecting, they select a future breeding site, colony, or mate and improve various skills and their physical condition to meet the requirements of reproduction. One precondition of successful reproduction is arri...

This longitudinal study investigated the influence of maturation on physical self-perceptions and the relationship with physical activity in early adolescent girls (N=150; mean age=12.79+/-0.31). Physical characteristics were measured and participants completed the Physical Activity Questionnaire for Children, the Children and Youth Physical Self-Perception Profile and the Pubertal Development ...

The purpose of this study is to examine the relative importance of media coverage and physician advice on the decision of women 40 years and older to obtain a mammogram. Five theoretical models, by which media coverage and physician advice may interact to affect individual health behavior, are presented. These models are tested with time-series regression analysis based on national-level data o...
