A review of research studies suggesting that girls who exercise vigorously may experience disruptions in maturational processes suggests that carefully-monitored sports participation and training have no effect on growth and maturation. (Author/CB)

This study of 10 seven- to nine-year-old boys was undertaken to determine the electromyographic activity of four muscles in the supporting leg during one foot static balancing. Results are presented and analyzed. (Author/MT)

The physiological responses and adaptations which occur as a result of resistance training, such as cardiovascular responses, serum lipid count, body composition, and neural adaptations are discussed. Changes in the endocrine system are also described. (JL)

The question of whether or not a lifelong program of exercise actually has a bearing on longevity is discussed. The effects of exercise on the aging process, and the longevity-exercise relationship are reviewed. The conflicting evidence on the subject is presented. (JL)

This study attempted to identify 27 kinematic variables for the jerk (in weightlifting) which would discriminate between weightlifters of different skill levels. Identifying these generic characteristics may help coaches in training weightlifters to overcome shortcomings in their performance. Methodology and results are discussed. (Author/JL)

A visit to the Exercise Physiology Laboratory at the University of Tennessee is part of a physical education class required of all undergraduate students. The laboratory demonstration stimulates student interest and enrollment in physical education. Benefits to students, the laboratory, and the school are described. (MT)

Research has shown that bone tissue responds to the forces of gravity and muscle contraction. The benefits of weight-bearing exercise in preventing or reversing bone mass loss related to osteoporosis is reviewed. The effects of weightlessness and immobilization, and the possible effects of athletic amenorrhea, on bone mineral density are…

Forty-eight runners with runner's knee were examined, treated, and studied for 8 months to identify the causes of this injury and its response to a particular regimen of conservative management. Results are discussed. (Author/DF)

Exchange of computer-assisted instruction (CAI) material between institutions is often impeded by incompatabilities of hardware, software, and curriculum. The use of a driver program is suggested to resolve these problems and facilitate exchange of instructional material. Technical details of the program described (and lessons used) are available…

The "fluency rules" therapy program for young children who stutter consists of seven rules designed to teach children about the physiologic concepts associated with fluent speech production. Pilot testing with nine children (three- to seven-years-old) demonstrated its effectiveness in producing fluent speech and maintaining fluency for a…

Healthy hematologic adaptations to exercise are described. The benefits of increased performance for elite athletes and reduced risk of heart attack for the general population are stressed. The advisability of increased amounts of fish in the diet and low doses of aspirin to reduce coronary risk factors are discussed. (Author/MT)

Discusses the physiology and biochemistry of the vitamin D endocrine system, including role of biological calcium and phosphorus, vitamin D metabolism, and related diseases. A 10-item, multiple-choice test which can be used to obtain continuing medical education credit is included. (JN)

This article focuses on three aspects of kinesiology: training principles, technique, and class design as they relate to injury prevention. Recommendations for prevention of some common dance injuries are offered. (MT)

Highlights the major parameters of current unemployment in the United States. Discusses the nature of stress, examines the stressful physical and emotional effects of being unemployed and the resulting behavior problems, and looks at the empirical and hypothetical links between unemployment, stress, and problems. (LLL)

Outlines the work of the anesthesiologist and the role of this doctor in medicine. Anesthetic procedures used for a gall bladder surgery are presented in detail. The potency of anesthetics pharmacology mechanisms producing unconsciousness and analgesia and equipment for anesthesiology are among the topic areas discussed. (DH)
