The process of a 1992 consensus conference that examined relationships among physical activity, fitness, and health variables is described. The conference involved internationally known scientists with relevant expertise. The paper discusses potential sources of physical activity, the benefits of physical activity, the possible harmful effects of…

Data on the dose-response gradient for the relation of physical activity or physical fitness to health and function are reviewed, refuting the idea that physical activity programs are either exercise for health or for fitness and suggesting that the key factor is the total energy expenditure of the activity. (SM)

Examines the effects of physical activity on depression and anxiety, discussing the scientific strength of studies on physical activity, depression, and anxiety against the standards of science accepted in epidemiology with a focus on the independence, consistency, dose-response gradient, and biological plausibility of the evidence. (Author/SM)

Introduces psychological perspectives on stress, noting conceptual models that guide sport and exercise psychology. After presenting key aspects of Lazarus' stress model, the paper reviews major lines of research related to stress within sport and exercise psychology. Lazarus suggests more information can be gained by considering emotion along…

Discusses the implications for professional practice and society of physical activity and stress, looking at the views of a series of papers that examined the issue of stress and exercise. The article focuses on what is missing in current research on stress and physical activity. (SM)

A body of psychoeducational data were gathered on 11 children (ages 8-14) who were gifted and learning disabled. Results from brain imaging and vision testing for hyperacuity and contrast sensitivity suggest that the interaction of high ability and learning disability results in brain and vision patterns unique to the learning-disabled/gifted…

Study tested the effect of exercise programs on bone mineral content (BMC) and BMC/bone width in 31 postmenopausal women. Subjects were placed in groups with aerobic exercise, aerobics plus upper-body weight training, or no exercise. Results indicate that regular exercise programs positively affect bone mineral maintenance in postmenopausal women.…

A cheap and simple model that can be made and used by pupils to study the human breathing mechanism is presented. A list of needed materials, procedures for construction, possible refinements, and method of use are included. (KR)

Human and electronic sensors that can indicate the presence of light, sound, temperature, pressure, and movement are discussed. Activities that investigate the human senses are described. Directions for making an electronic touch sensor are provided. (KR)

A multiphasic plan to improve lecture effectiveness which centers on teaching behaviors that can facilitate the learning process is described. Lectures were evaluated based on the inclusion of behaviors such as objectives, advance organizers, questioning, wait-time, and use of teaching aids. Included are the results and a discussion. (KR)

Examines 539 undergraduate course catalogs to determine the percentage of institutions offering courses in physiological psychology, biological psychology, both, or neither. Finds 64.1 percent of the institutions studied offered physiological psychology, and 11.3 percent offer biological psychology. Finds catalog descriptions reveal confusion over…

Rapid-cycling brassicas can be used in the classroom to teach concepts such as plant growth, tropisms, floral reproduction, pollination, embryonic development, and plant genetics. Directions on how to obtain them for classroom use and how they may be grown are included. Practical physiology and genetics exercises are listed. (KR)

Discusses chronic fatigue syndrome as it affects elite athletes, noting that overtraining may mimic it. In some cases, athletes who have it perform exceedingly well in the face of debilitating fatigue. Among athletes and nonathletes, the cause and the mind-body connection are areas of controversy and research. (Author/SM)

Examines whether prepubescents are trainable in competitive sports, noting trainability differences between prepubescents and older groups. Changes in maximal aerobic power, metabolic cost of walking and running, muscle strength and power, and local muscle endurance are examined. Strength training is recommended only for rehabilitation or…

Discusses management of common overuse disorders, which are often a result of repetitive stress. Reducing inflammation through icing, rest, and use of nonsteroidal anti-inflammatory agents is the primary treatment goal. Patients taking anti-inflammatories must be cautioned against returning to activity too soon because the medication's analgesic…
