The plasma amino acid profiles of 10 children with autism on gluten and casein restricted diets and 26 on unrestricted diets were reviewed. There was a trend for the children on restricted diets to have an increased prevalence of essential amino acid deficiencies and lower plasma levels of essential acids. (Contains references.)

A review of literature related to the effectiveness of dietary interventions in controlling blood pressure concludes that the existing literature contains sufficient evidence to identify successful dietary intervention techniques, in either the short or long term, which modify sodium intake, fat intake, or calorie intake in middle-aged men.

Adults (N=142) who engaged in a 12-week moderate exercise program requiring the maintenance of training state exercise heart rates for a minimum of 20 minutes, 3 times a week, experienced an improvement in cardiovascular functioning regardless of age and/or sex. (Author/IAH)

In terms of physical impact, recent studies suggest that many benefits previously attributed to exercise as a factor in weight loss do not exist. Researchers do seem to agree that exercise does have a positive effect on body composition during weight loss. (IAH)

This article addresses dangerous dieting techniques used by athletes and provides coaches and teachers specific strategies to aid in preventing eating-related disorders among athletes. Symptoms of anorexia and of bulimia are described. (JL)

Presents 12 discrepant event demonstrations on various concepts related to density to make physical science more interesting and fun. Demonstrations are organized into the "5E" instructional model (engagement, exploration, explanation, elaboration, and evaluation). (MKR)

Studied maintenance procedures in 201 overweight female participants who completed a very-low-calorie diet. Posed two questions: (1) Would stimulus narrowing during the reintroduction of solid food improve weight losses and the maintenance of those losses? and (2) Would reintroduction of foods dependent on progress in losing or maintaining weight…

How children learn to construct and enact masculinities and femininities is clearly an issue for education and one that has been explored in a wide variety of ways.

These increases have given rise to concern about children's health and well-being. The terminology used in these studies varies considerably. However, whatever the terminology used, such studies are generally based on weight…

This article discusses field tests that can be used in physical education programs. The most common field tests are anthropometric measurements, which include body mass index (BMI), girth measurements, and skinfold testing. Another field test that is gaining popularity is bioelectrical impedance analysis (BIA). Each method has particular strengths…
