Flexibility is an important aspect of all sports and recreational activities. Flexibility can be developed and maintained by stretching exercises. Exercises designed to develop flexibility in ankle joints, knees, hips, and the lower back are presented. (JN)

Presents a list of handbooks, published in the Handbook of Physiology series, that present physiological knowledge and concepts. Also reviews the history of this effort and sales data for handbooks within the areas of neurophysiology, respiration, circulation, environment, adipose tissue, and the alimentary canal. (CS)

Describes a system that monitors intestinal motility in vivo which is very sensitive, minimally injurious to the tissue, and inexpensive. Used are two balloons, one of which is inserted into the intestinal lumen and the other suspended from a force transducer. (CS)

Family configuration correlates of fluid intelligence and crystallized intelligence constructs are examined. (SS)

Discusses the physiology of endogenous pyrogen (EP), the fever-producing factor of cellular origin. Included are: its hormone-like role, its molecular nature, bioassay procedures, cellular production and mechanisms of EP action. (SA)

This syllabus reviews information concerning calcium and phosphate regulation. Topics of interest include the following: calcium metabolism, phosphorus metabolism, bone, parathyroid hormone, calcitonin, and vitamin D. (CS)

Discusses differences between smell and taste, comparing these senses in organisms in aquatic and terrestrial environments. Describes the chemical environment underwater and in air, differences in chemoreceptors to receive stimuli, and the organs, brain, and behavior involved in chemoreception. (CS)

Salient concerns for practitioners of fitness testing are identified. (JD)

Discusses several of the plant responses to the environment and ways that these responses can be demonstrated. Includes phytochrome-controlled growth, phototropism, and geotropism. (CS)

Describes procedures for monitoring students' responses in heart rate to various stimuli by the use of an electronic monitoring device strapped to the wrist. (CS)

This formal report from the Committee on Careers in Physiology of the American Physiological Society summarizes important aspects related to predoctoral and postdoctoral training programs and career opportunities in physiology. (CS)

A high school class in running for physical fitness is described; the course is designed to introduce students to lifetime aerobic fitness. (JMF)

A multivariate post hoc procedure (the Roy-Bose procedure) which allows for the construction of an infinite number of confidence intervals or probability statements concerning the p variables, all of which hold at a 100(1-a) percent level of confidence, is demonstrated and compared to other procedures. (JD)

The lack of physician knowledge in the diagnosis and management of sleep disorders is discussed. An examination of physicians demonstrated knowledge deficiencies and a survey of medical schools showed that 46 percent offered no training in the area of sleep physiology or disorders. Recommendations for addressing the situation are offered. (JMD)

The article is a condensation of materials from the winter survival unit of a Canadian snow ecology course. The unit covers: cold physiology, frostbite, snowblindness, hypothermia, winter campout, and survival strategies. (SB)
