This article discusses the beneficial aspects of isokinetics--resistive exercise that varies according to the individual's skeletal leverage. (JS)

This article discusses the case for and against running. (JS)

This study was an attempt to determine how selected cardiovascular and respiratory parameters adapted to the phenomenon of second wind. Subjects were tested on a treadmill run. (JS)

Designed as a supplement to traditional writing texts, this workbook contains activities that allow students to form grammatically sophisticated sentences without having to study formal grammar. The 68 lessons in the workbook progress from relatively simple to complex, with each stressing a particular way of combining sentences. The various…

The physical manifestations of the aging process are described, and the benefits of a program of regular exercise for people over the age of 65 are discussed. (JD)

This manual is the final report of a study on the development of methods and programs to promote physical fitness among police officers. In twelve chapters the following topics are covered: (1) principles of exercise; (2) research methodology used to compile this manual; (3) results of physical fitness evaluation of program volunteers; (4)…

This study attempts to appraise the effectiveness of chronic heavy exercise on 13 male swimmers from 10 to 17 years of age. The experimental group trained six days a week, often with more than one workout per day. During this period, the principles of interval training were employed in conjunction with high-intensity swimming. At the completion of…

This study assessed the effects of varied rest intervals following a five-minute warm-up upon subsequent ratings of perceived exertion (RPE), heart rate (HR), and state anxiety during an exercise period. The subjects were 16 male college students. Each subject was tested under four experimental conditions following a five-minute warm-up on a…

Analysis of the human and mechanical factors inherent in ergometry suggest many strategies for the improvement of experiments related to exertion. The resistive principles of gravitation, friction, elasticity, viscosity, magnetism, and inertia used in ergometers impose different restraints on experiments. The suitability of different resistive…

This booklet is designed to make available research findins concerning distance running with interpretations, for practical applications, and to point out areas of needed research. Chapter 1, "Describing the Distance Runner," considers the following aspects in relation to the distance runner: a) anatomical characteristics, b) aging, c) strength…

This speech begins with the presentation of a conceptual scheme of the physical working capacity of a person starting a training program. The scheme shows that after exercise, when recovery begins and sufficient time elapses, the individual recovers and adapts to a level of physical working capacity which is higher than his starting level. From…

This guide outlines a course designed to assist students in grades 7-12 who have disabilities and cannot successfully take part in a general physical education program. The course is devoted to developing skill in recreational sports and games, developing understanding of individual limitations and potentialities, aiding the student in personal…

This paper begins by defining the terms "weight training,""weight lifting,""strength,""power," and "muscular endurance.""Weight training" is differentiated from "weight lifting" and defined as a systematic series of resistance exercises designed to promote physical development and conditioning or to rehabilitate persons who have suffered injury or…
