Students are provided with a mystery concerning dogs that are paralyzed. This motivates a laboratory exercise to measure parameters from the dog's "blood" to determine whether the paralysis is due to pesticide poisoning or an autoimmune attack on nerve myelin. Most of the materials are available from the grocery store. The real-world nature of the…

Purpose: The purpose of the present research was to test how behavioral regulations are mediated between basic psychological needs and psychological well-being and ill-being in a sample of team-sport coaches. Based on self-determination theory, we hypothesized a model where satisfaction and thwarting of the basic psychological needs predicted…

Purpose: The purpose of this study was to examine region, age, and sex profiles of physical fitness in Hungarian youth. Method: A sample of 2,602 Hungarian youth aged 10 to 18 years old completed a series of physical fitness field tests: the Progressive Aerobic Cardiorespiratory Endurance Run (PACER) fitness test, body mass index (BMI), percent…

Purpose: Identifying and addressing poor nutritional status in school-aged children is often not prioritized relative to HIV/AIDS treatment. The purpose of this paper is to elucidate the benefits of integrating nutrition (assessment and culturally acceptable food supplement intervention) in the treatment strategy for this target group.…

Female high school athletes are an at-risk population for the Female Athlete Triad--a syndrome including low energy availability (with or without disordered eating), menstrual dysfunction, and low bone mineral density. School nurses can play an important role in reducing the health burden of this syndrome, by educating coaches and athletes, and by…

This article reviews the results of a school-based self-management intervention for Chinese obese children at risk for metabolic syndrome. Twenty-eight Chinese obese children (M age?=?10 years) and their parents participated in the study. Metabolic syndrome risk factors were measured pre- and post-intervention. The risk factors included Body Mass…

In the present study, we investigated a hypothesized quartic relationship (meaning three inflection points) between exercise heart rate (HR) and preferred music tempo. Initial theoretical predictions suggested a positive linear relationship (Iwanaga, 1995a, 1995b); however, recent experimental work has shown that as exercise HR increases, step…

Individuals' relative awareness of thematic and taxonomic relations is influenced by factors such as language and background knowledge. Relatively weak in Korean language skills and also having relatively limited social opportunities, Korean deaf adolescents might be different from hearing adolescents in how they make decisions in taxonomically…

Most undergraduate physiology texts describe veins simply as reservoirs for blood and conduits for return of blood to the heart. This article describes a laboratory exercise that can be performed by students to demonstrate that veins are much more than reservoirs and conduits for blood flow: they possess a dynamic rhythmic contraction. In this…

In 2004 and 2007, the American Physiological Society (APS) Trainee Advisory Committee (TAC) conducted surveys of graduate students, postdoctoral fellows, and new investigators in physiology to identify topics and issues important to those trainees. Two major trends emerged from the data. First, trainees in 2007 expressed somewhat greater interest…

The present study investigated the current functions of Deaf clubs in Cyprus and in Greece. The researchers conducted in-depth semistructured interviews with 24 Cypriot and 22 Greek deaf individuals ages 19-54 years. The researchers found that the Deaf clubs in both countries provide a gathering place for deaf people, organize social and sport…

In patients with the callosal type of anarchic-hand syndrome, the left hand often does not act as intended and counteracts the right hand. Reports are scarce about the underlying neurophysiological mechanisms. We report the case G.H. who developed the syndrome after infarction of the left arteria pericallosa. It has been suggested that the…

To jog around the periphery of a carousel at rest requires that the jogger experience a constant state of acceleration perpendicular to the direction of motion and directed toward the axis of rotation (centripetal). The jogger could achieve this centripetal acceleration by leaning inward, thereby using a horizontal weight component to provide the…

Purpose: Physiologic reactivity profiles were generated for 9 school-age children with a history of stuttering. Utilizing salivary sampling, stress biomarkers cortisol and alpha-amylase were measured in response to normal daily stressors. Children with a history of stuttering were characterized as high or low autonomic reactors when compared to…

Excitatory anodal transcranial direct current stimulation (A-tDCS) over the left dorsal prefrontal cortex (DPFC) has been shown to improve language production. The present study examined neurophysiological underpinnings of this effect. In a single-blinded within-subject design, we traced effects of A-tDCS compared to sham stimulation over the left…
