Suggests that sound pollution constitutes a severe problem to the urban dweller. Excessive exposure of humans to noise produces both physical and psychological manifestations. Suggests that control of industrial, aircraft, and community noise must be recognized and accepted as a major factor in urban planning and development. Bibliography. (LC)

Basic research in autism is reviewed. Reports that there is mounting indication, but as yet inconclusive evidence, of unique physiologic disturbances etiologically related to autism and that some of the physiologic disturbances found in autistic children are also present in children with other developmental disorders. (Author/SBH)

Individuals react differently to caffeine intake but tests indicate that ingesting coffee has a minimal influence on motor performance. (JD)

The University of Hartford planned fitness trail will allow students to develop their bodies by providing a jogging route to improve cardiovascular fitness and exercise stations designed to provide warm-up exercises and improve strength, flexibility, balance, and endurance. (Author/MLF)

Better distance runners perform at a higher percentage of their maximal aerobic power than do distance runners of poorer ability. (JD)

The physiological mechanics of kayaking and canoeing are examined. (JD)

A report is given on alterations in blood pressure, heart rate, left ventricular ejection time, and myocardial oxygen consumption during isometric contraction in a closed heated environment. (JD)

Physical activity combined with proper diet will lead to weight loss without strenuous exercising. (JD)

Proposes a hypothesis suggesting that parts of the central nervous system that contain norepinephrine and dopamine are dynamically interrelated under stressful conditions in a compensatory way. (MLH)

Outlines methods for manipulating multiple gas data so as to gain the greatest amount of insight into the properties of ventilation-perfusion distributions. Refers to data corresponding to normal and abnormal lungs. Uses a two-dimensional framework with the respiratory gases of oxygen and carbon dioxide. (CS)

Reviews the literature on the left ventricular structural adaptations induced by resistance/strength exercise, focusing on human work, particularly well-trained strength athletes engaged in regular, moderate- to high-intensity resistance training (RT). The article discusses both genders and examines the use of anabolic-androgenic steroids in…

Tested the hypothesis that wall thickness, but not chamber dimension, would be larger in endurance- and power-trained athletes with spinal cord injuries than in sedentary people with spinal cord injuries. Data on 11 power-trained and 5 sedentary participants showed no statistically significant differences between groups, though there was a trend…

Explores the role of macronutrients in exercise, examining research pertaining to exercise intensity, exercise duration, macronutrient intake, and mode of exercise as they pertain to both athletes and recreational exercisers. The paper explains that coaches and trainers must interpret and apply research findings to individual exercisers,…
