Purpose: The focus of this research effort was to examine the effect of a sound-field amplification system on managerial time in the beginning of class in a physical education setting. Method: A multiple baseline design across participants was used to measure change in the managerial time of 2 middle school female physical education teachers using…

In this study, the training effects of static and dynamic exercise programs on the firing patterns of 450 single motor units (SMU) in the human tibialis anterior muscle were investigated. In a six week program, the static group (N=5) participated in daily high intensity, short duration, isometric exercises while the dynamic group (N=5)…

The purpose of this study is to investigate the manner in which selected mechanical elements of the running stride are altered with accompanying variations in the speed of running and the slope upon which running occurs. Subjects, 16 intercollegiate runners, were marked at reference points of the body pertinent to this study and filmed twice…

This is a collection of significant papers by leading authorities, compiled by the American Association of Health, Physical Education, and Recreation's Kinesiology Committee of the Physical Education Division. The following papers are included in this collection: "Supporting Biomechanics Subject Matter in the Undergraduate Curriculum";…

THE PRIMARY OBJECTIVE OF THIS STUDY WAS THE DEVELOPMENT OF A SYSTEM WHICH WOULD ALLOW THE MEASUREMENT AND ANALYSIS OF PHYSIOLOGICAL RESPONSE OF STUDENTS VIEWING FILM MATERIAL UNDER CONVENTIONAL CLASSROOM CONDITIONS. THE GALVANIC SKIN RESPONSE (GSR) WAS MEASURED BY SENSORS AND USED AS AN INDICATOR OF STUDENT INTERACTION WITH THE FILM MATERIAL. IN…

A study of nasal mucociliary transport in 11 healthy subjects before and after they jogged 8-10 kilometers indicated that the transport time was significantly longer after jogging than before jogging. (Author/CB)

This article reviews research on blood doping, the transfusion of red blood cells to improve oxygen delivery and, thereby, endurance. The use and rationale for blood doping are explained. (Author/MT)

The many different techniques of modern dance each make unique demands on the dancer's body. A study of 164 modern dancers compared injury sites and frequency with the dance technique. Results indicate technique is a factor in injuries. (Author/MT)

Argues that the term skeleton is not a word denoting a structure but a word denoting a function--that of allowing animals the freedom of self-motivated purposive local motion. Indeed a skeleton is a necessary prerequisite for there to be locomotion at all.'' (Author/AL)

This study examined the linkage between elevated blood serotonin in autism and the presence of circulating autoantibodies against the serotonin 5HT receptor. Results showed elevated blood serotonin was not closely related to inhibition of serotonin binding by antibody-rich blood fractions. Data were insufficient to determine whether people with…

This article presents a review of reverse correlation in neurophysiology. We discuss the basis of reverse correlation in linear transducers and in spiking neurons. The application of reverse correlation to measure the receptive fields of visual neurons using white noise and m-sequences, and classical findings about spatial and color processing in…
