Selected time components of the cardiac cycle were determined during breathing in air, breathing through a snorkel during face immersion, apnea in air, and apnea during face immersion. (PBS)

Describes a project launched by graduate student volunteers of Let's Talk Science at the University of Western Ontario that introduces senior high school students to research presentations given by undergraduate physiology students. (Author/AIM)

Compared the metabolic and cardiovascular responses of young and older women while performing shallow water exercise (SWE). Overall, SWE elicited metabolic and cardiovascular responses that met American College of Sports Medicine's guidelines for establishing health benefits. Older females self-selected a greater relative exercise intensity during…

Presents an activity in which students design, construct, and test "super ears" to investigate sound and hearing. Students work in groups of three and explore how the outer ear funnels sound waves to the inner ear and how human hearing compares to that of other animals. (NB)

Describes cooperation with the Saint Louis Zoo to provide opportunities for elementary school students to learn about bones, how animals move, what they eat, and how much they grow. Uses biofacts which include bones, skulls, and other parts to make the laboratory a hands-on experience for students. (YDS)

Presents a hands-on activity that uses a skeleton to study anatomy and physiology concepts and explore the relationship between form and function in nature. (NB)

Analyzes data concerning the status of faculty at American medical schools who hold Ph.D. degrees in physiology and faculty members with appointments in departments of physiology. Data show a decline in numbers of Ph.D.s in animal and human physiology awarded to Americans since 1980. Discusses programs and initiatives to increase student interest…

Reports on a classroom instruction project in a community college anatomy and physiology course designed to focus less on rote memorization and more on active learning. Discusses the students, procedures, evaluation of student learning, student reactions, and student outcomes. Concludes that most students felt positive about their experiences with…

Strength training is an effective method of developing musculoskeletal strength and is often prescribed for fitness, health, and for prevention and rehabilitation of orthopedic injuries. This paper describes and presents a rationale for the population-specific strength training guidelines established by major health organizations. (SM)

Describes a physiology laboratory designed to localize digestive enzymes within the digestive tract of cockroaches and develop a general conclusion about the similarities to mammalian digestion. This approach not only demonstrates the practicality of lecture material, but also provides a springboard for independent research opportunities.…

Examined use of psychological state words during mother-child play sessions at age 3 in 31 children diagnosed with delayed expressive language at 24-31 months and age-matched typically-developing comparison children. Children and mothers in the late talker group made more references to physiological states and fewer references to cognitive states…

A review of literature on exercise and arthritis considers relevant epidemiologic and experimental studies of animals and humans, focusing on the relationship between running and osteoarthritis. No conclusive evidence exists that running causes osteoarthritis; research trends suggest that running may slow the functional aspects of musculoskeletal…

Aerobic and resistance exercise are currently prescribed by physicians to treat chronic pain. However, patient fitness level must improve before he/she feels better. Pain management programs help patients become more active so they can function at work and home. (SM)

A method of obtaining a crude mitochondrial extract from sheep and beef heart is described. The respiratory substrates succinate and malate are examined as well as the inhibitory effect of malonate. An interface with a microcomputer for plotting colorimeter results is discussed. (Author/CW)
