Student evaluations of faculty are important components of the medical curriculum and faculty development. To improve the effectiveness and timeliness of student evaluations of faculty in the physiology course, we investigated whether evaluations submitted during the course differed from those submitted after completion of the course. A secure…

This three-part text, which is concerned with human functions under stress of muscular activity, provides a basis for the study of physical fitness and athletic training. Part 1 reviews pertinent areas of basic physiology. Muscles, the nervous system, the heart, respiratory system, exercise metabolism, and the endocrine system are reviewed. Part 2…

Maximal oxygen intake and associated physiological variables were measured during strenuous exercise on women subjects (N=20 physical education majors). Following assessment of maximal oxygen intake, all subjects underwent a performance test at the work level which had elicited their maximal oxygen intake. Mean maximal oxygen intake was 41.32…

This study investigated the effects of the velocity of muscular contraction on the effective force (torque) exerted by forty 18- to 21-year-old males. The dynomemeter lever arm, the fulcrum of which was aligned with the axis of elbow rotation, allowed extension and flexion for the subjects. All subjects were tested at three velocities (.10, .20,…

In this document, "middle age" is defined as the 26- to 65-year age span during which there is a steady decline of both physical and mental capabilities and a change for the worse in personality traits. The document summarizes the findings of recent training experiments in adult health and physical education that indicate possible ways of…

Discusses different foods with reference to oxidation and energy production. Amino acid assays are provided for eggs, steak, rice, and lentils and white and dark turkey meat is analyzed for energy and power outputs. (MA)

This study examined the isokinetic peak torque at the highest speed of muscle shortening related to age, sex, and physical performance. (MM)

Though often discussed as a discrete event, puberty comprises one segment of a larger developmental continuum and is notable for rapid transformation across a multitude of domains. Research suggests that an earlier rate of pubertal maturation in girls correlates with a number of detrimental outcomes compared with on-time or later maturation. The…

Previous experiments in the hippocampal CA1 area have shown that corticosterone can facilitate long-term potentiation (LTP) in a rapid non-genomic fashion, while the same hormone suppresses LTP that is induced several hours after hormone application. Here, we elaborated on this finding by examining whether corticosterone exerts opposite effects on…

Massage therapy has been notably effective in preventing prematurity, enhancing growth of infants, increasing attentiveness, decreasing depression and aggression, alleviating motor problems, reducing pain, and enhancing immune function. This review covers massage therapy research from the last decade, as an update to the American Psychologist 1998…

It is common to see chapters on acid-base physiology state that the goal of acid-base regulatory mechanisms is to maintain the pH of arterial plasma and not arterial PCO [subscript 2] (Pa[subscript CO[subscript 2]]) or plasma HCO[subscript 3]. A hypothetical situation in which the (Pa[subscript CO[subscript 2]]) of arterial plasma is 80 mmHg and…

Models of stress and health suggest that emotions mediate the effects of stress on health; yet meta-analytic reviews have not confirmed these relationships. Categorizations of emotions along broad dimensions such as valence (e.g., positive and negative affect) may obscure important information about the effects of specific emotions on physiology.…

The purpose of this exploratory study was to examine the relationship among different dimensions of trait anxiety (social concerns, physiological anxiety, and worry/oversensitivity), demographic variables (age and gender), and school adjustment (attitude to school and attitude to teachers) in children and adolescents. The study participants,…

Without a consensually validated definition and a set of diagnostic criteria, counselors lack the necessary assessment and treatment tools to work effectively with clients with process addictions and their families. Necessary criteria and the results of a needs assessment are presented.
