The physiological responses and adaptations which occur as a result of resistance training, such as cardiovascular responses, serum lipid count, body composition, and neural adaptations are discussed. Changes in the endocrine system are also described. (JL)

A method for testing oxygen uptake while subjects are swimming is described and analyzed. (JD)

This document examines the effects of strength-development programs on the improvement of motor skills and sports competencies. Part one defines various terms used throughout the development studies. Part two discusses the mixed results of experiments involving speed of movement as the motor item indicative of strength development. Part three…

Cardiovascular fitness is related to dance. Dance develops strength, endurance, body type, flexibility, coordination, speed, agility, balance, intelligence, and creativity. (JMF)

Physical education can serve as a vehicle for teaching science and make student understanding of certain personal health-related science concepts meaningful. Describes activities involving the musculoskeletal system, the nervous system, and the cardiovascular system. (DKM)

Exercises and classroom activities that familiarize students with the "human body machine" are the focus of this article which addresses the decline in elementary student health and fitness. A reproducible worksheet, "Benefits of Exercise Worksheet", is included. (IAH)

To evaluate the effects of drinking glucose and fructose before prolonged exercise, six female runners were given glucose, fructose, saccharin, or plain water to drink before running to exhaustion. Metabolic processes were monitored. The best performance came from those drinking water alone. Fructose seemed preferable to glucose, however.…

In an attempt to identify physiological factors that account for success in distance running, researchers evaluated relationships among ventilatory threshold, running economy, and distance running performance. Subjects were trained male runners with similar maximal aerobic power. (Authors/PP)

Oxygen uptake and heart rate kinetics for submaximum exercise (bicycle riding) were compared in prepubescent boys and adult men. Resulting data suggest that children and adults do not differ significantly in cardiorespiratory adjustments during low-intensity exercise. (Authors/PP)

Described is a method for integrating electrical and mechanical events of the cardiac cycle by measuring systolic time intervals, which involves simultaneous recording of the ECG, a phonocardiogram, and the contour of the carotid pulse. Both resting and stress change data are provided as bases for class discussion. (CS)

Discusses some calculations and demonstrations illustrating the role of physics in cardiovascular system. Describes a model for the system, work done by the heart, pressure in blood vessel, and gravitational effects. (YP)

Described is a cardiovascular simulator which illustrates the use of a catheter-coupled external transducer for dynamic pressure measurements in the circulatory system. With the simulator, students can observe the effects of stroke volume and rate upon maximum, minimum, and mean arterial pressure. (Author/GA)

Explains the principles of the Doppler ultrasound technique and reviews its potential applications to the teaching of cardiovascular physiology. Identifies the instrumentation needed for this technique; provides examples and illustrations of the waveforms from the ultrasound blood velocimeter. (ML)

Describes a game developed for school children which addresses part of the Science National Curriculum. The board is a human body with organs on view. Questions relate to different organ systems, body parts, and processes. Topics include breathing, digestion and metabolism, blood and circulation, and the sensory organs and teeth. (AIM)

Describes an experiment designed to introduce biochemistry students to the specificity of an analytical method which uses an enzyme to quantitate its substrate. Includes the use of toxicity charts together with the concept of the biological half-life of a drug. (TW)
