This study, designed to determine the effect of a prolonged running bout on the measurement of percent fat, produced erroneously low readings. It is suggested that previous exercise and state of hydration of subjects should be controlled prior to percent fat determination by hydrostatic weighing or scintillation counting. (MJB)

Presents a brief review of the chemistry of the plant cell wall. Included topics are: analytical techniques, structure, growth, and maturation. (BB)

Reviews studies of regulation of nasal airway resistance (Rn). Describes methods of calculating Rn by measuring pressure-flow relationship. Data are presented on improved methods for measuring Rn and effects for expiratory and inspiratory Rn after topical application of phenylephrine nasal decongestant spray. (Author/SA)

It was concluded that continuous and interval training methods were equally effective in developing endurance when the same total amount of work was performed. (MM)

Stress has become a modern watchword with a variety of meanings, both popular and scientific. Recent studies in the physiology of stress have important implications for executive behavior.

Presents a crossword puzzle with 99 answers designed as a final exam in neurophysiology. Includes the puzzle, clues, and answers. (MA)

The Gordon Research Conferences were established to stimulate research in universities, research foundations, and industrial laboratories. The topics for the conferences are listed as well as the locations and scheduled presentations at each conference. (CS)

This study of high sustained heart rates observed during circuit weight training involving high resistance and low repetitions indicates that such training has no concurrent cardiovascular training effect. (MB)

Discusses the discovery, physiological function and the three roles (the bridge, the gate, and the fence) of the junctions between epithelial cells. Experimental usefulness of epithelia in studying basic questions common to all cell membranes, such as extraction of channels and carriers, or origin of ion or nonelectrolyte selectivity, is…

Compared the energy cost of treadmill walking in pairs of obese and lean adolescent boys matched for total body mass. Results found no intergroup differences in the net energy cost at the two lower speeds, but obese boys expended more energy at a higher speed. Heart rate was considerably higher in obese boys. Body mass, rather than adiposity, was…

Reports on a simple classroom exercise that investigates whether students' beliefs of what they think should happen influences their measurements. The exercise also provides a framework for discussing the challenges that human belief systems bring to the discipline of using the scientific process. Results suggest that students' preconceived…

Presents a lab that can be offered after students have learned the basic anatomy and physiology of the various phyla, the primary objective of which is to explore and apply their acquired knowledge to a new situation. Involves exploring the anatomy and life-style of the squid. (JRH)

Briefly discusses the work of physician and physical educator Delphine Hanna, examining the philosophy of medicine and explaining how physical education, kinesiology, and sport and exercise science in the United States are all rooted in medical tradition. The paper also discusses the subjective and objective understanding of human body movement.…

Examined the physiological responses of elderly Japanese women to a well-rounded exercise program performed in water. Results indicated that the 12-week program elicited significant improvements in intervention group women's cardiorespiratory fitness, muscular strength, agility, flexibility, body fat, and total cholesterol. Water-based exercise…
