The study tested the effect of aerobic exercise training on executive function in overweight children. Ninety-four sedentary, overweight but otherwise healthy children (mean age = 9.2 years, body mass index [greater than or equal to] 85th percentile) were randomized to a low-dose (20 min/day exercise), high-dose (40 min/day exercise), or control…

Much of the work in academic writing has focused on the cognitive rather than the affective and social aspects involved in project-based writing. Emphasis in past research has been on skills and processes of writing rather than on affective factors such as motivation, attitudes, feelings or social factors involving intrapersonal and interpersonal…

Roughly 54 million people with disabilities live in the U.S., and there are many more millions of people with disabilities around the world. Not surprisingly, differences among and between people with disabilities are often as notable as differences between people with and without disabilities. While the lack of homogeneity among people with…

In the early 1970s, both my academic career and the psychology subdiscipline within kinesiology began as "social psychology and physical activity." Since then, sport and exercise psychology research has shifted away from the social to a narrower bio-psycho-(no social) approach, and professional practice has focused on the elite rather…

Growth and development have a profound effect on physical fitness, response to exercise, and exercise programming in children. This article reviews the essential pediatric exercise physiology concepts relevant to physical education programs for K-6 children. Indices of physical fitness such as cardiorespiratory endurance, muscular strength, and…

Many undergraduate institutions offer individual research opportunities for upper-level students in independent study courses and summer undergraduate research programs. These are necessarily limited to a small number of students. Greater numbers of students can benefit from incorporating student-directed investigative experiences into…

Objective: To explore intergenerational health habits and compare differences between urban and rural families. Methods: A total of 2500 families with children ages 6-18 in China were surveyed regarding their health habits. Results: Urban families reported significantly greater food variety and more time exercising (for fathers and children) than…

This study has attempted to explore media influences on social and cultural change, in particular the impact of the media on individuals and groups' practice of exercise. It suggests that the media has been in some way successful in gaining male support and has eliminated some gender hostilities, resulting in a little change to the status quo of…

This paper describes a number of factors which go into determining weight. The paper describes what calories are, how caloric expenditure is measured, and why caloric expenditure is different for different people. The paper then outlines the way the body tends to adjust food intake and exercise to maintain a constant body weight. It is speculated…

This survey of exercise stress testing programs in the United States concludes that the rapid growth and diversity of these services have created a need for increased communication and cooperation among professionals concerning standards relative to procedures, protocols, and personnel.

A primary goal of the cardiovascular evaluation of exercisers is to identify conditions that carry the risk of exercise-related sudden death. These conditions, which are found in a careful evaluation of the patient, are identifed and described in detail. (Author/JL)

Computers used in employee fitness programs help motivate participants by providing immediate feedback. The computer is used to record employee membership, participant check-in and check-out, fitness and medical testing, and exercise logging. A description of Tenneco's health program is offered. (DF)

Exercise science represents an integrated approach to the study of the physiological, biochemical, and mechanical adaptations of humans to stresses imposed by a variety of physical performances as well as ambient conditions such as temperature and humidity. (MLW)

Perceived exertion scales, based on subjective perception of energy output, are gaining respect as prescribing and monitoring tools for individual exercise programs. A review of recent literature indicates growing research interest in applications for individuals who are elderly, inactive, or subject to medical conditions such as angina. (IAH)

The purpose of this investigation was to study the effects of an acute bout of aerobic exercise on state anxiety of women while controlling for iron status (hemoglobin and serum ferritin). Participants were 24 active women, ages 18-20 years (n=12) and 35-45 years (n=12). In addition to a nonexercise control condition, participants completed one…
