Developed a cardiorespiratory endurance test that retained the inherent advantages of submaximal testing while eliminating reliance on heart rate measurement in predicting maximum oxygen uptake (VO2max). College students completed three exercise tests. The 1.5-mile endurance test predicted VO2max from submaximal exercise without requiring heart…

Discusses how to choose physical activities with psychosocial objectives in mind in order to create avenues for practice and support for new behaviors, highlighting seven psychosocial dimensions of change (socialibility, spontaneity, self-motivation, aggressiveness, competitiveness, mental focus, and adventurousness). The paper examines the…

Explains how to use bats to introduce different biological concepts such as classification and phylogeny, altruistic behavior, flight, coevolution, or physiological adaptations. Discusses common myths regarding bats and provides information on additional classroom materials. (YDS)

When patients experience fatigue and muscle cramps beyond exercise adaptation, physicians should consider metabolic myopathies. The most common conditions seen in active patients are myoadenylate deaminase deficiency and disorders such as McArdle's disease. Targeted family histories and basic laboratory studies help rule out conditions mimicking…

Evaluated the meaningfulness of exercise training responses in patients with end stage renal disease. Data were collected on 18 patients who completed a stationary cycling training regime. Although conventional statistical analyses indicated that exercise training favorably altered participants' peak and sub-maximal exercise capacity, there was…

Menopause is associated with many different health effects and symptoms. This paper explains that regular exercise can play a critical role in protecting health and battling the increased risk of cardiovascular disease, osteoporosis, pelvic floor atrophy, and joint stiffness associated with menopause. Exercise programs for menopausal women should…

Investigated the effect of intense exercise training on physical fitness, coronary heart disease, bone mineral density (BMD), and parameters related to quality of life in early postmenopausal women with osteopenia. Data on woman in control and exercise training groups indicated that the intense exercise training program was effective in improving…

Debate continues as to whether exercise training accelerates the growth of coronary collateral vessels. Animal research has produced positive results, but human studies have been disappointing, largely because of problems in experimental design and methodology. (IAH)

Presented are the abstracts to sessions of the Specialty Meeting of the American Physiological Society held October 6-10, 1990, in Orlando, Florida. Included are plenary lectures, symposia, poster and slide sessions, and schedules for the conference. (CW)

Team physicians and coaches need a working knowledge of the pathophysiology of sports injuries to the larynx and trachea, carefully examining any such injuries because they could develop slowly and without symptoms into a compromised airway. Laryngeal and tracheal anatomy are discussed along with diagnosis and treatment. (SM)

Arthritic patients who regularly do aerobic exercise make significant gains in aerobic and functional status, and in subjective areas like pain tolerance and mood. Still, they are often advised to curtail physical activity. Guidelines are presented for physicians prescribing aerobic exercise. An exercise tolerance test is recommended. (SM)

Autopsy analysis of eight dyslexic brains found that the ordinary asymmetry in a language-relevant area of the temporal lobe was missing. The greater development of the right side may reflect an increase in the total number of neurons involved in language processing, resulting in changes in interhemispheric interactions. (JDD)

No differences were observed between six adults and six six-year-olds in measures of frequency selectivity and comodulation masking release. Children were less able to detect signals in noise backgrounds where the signal had perceptual qualities similar to the noise or in noise backgrounds having high degrees of fluctuation. (Author/JDD)

Averaged cortically evoked potentials to frequency-modulated tones were obtained from 12 children with specific language impairment (SLI) and 12 controls. Responses from SLI children were not significantly different from those of normal language learners, indicating no difference between groups with respect to neural systems involved with…

One experiment determined that the minimum angle at which infants can discriminate 2 sound presentations decreases substantially toward 48 weeks of age. In 3 succeeding experiments, infants aged 16, 20, and 28 weeks were able to discriminate sounds presented to each ear between 50 and 75 microseconds apart. (BC)
