As a way to address the serious obesity epidemic in the United States, many physical education classes have become fitness centers designed to raise heart rates and burn calories. An unintended consequence of this emphasis on fitness, however, is the lack of attention to motor skill development. Motor skills do not develop miraculously from one…

Stability in cardiac indicators before birth and their utility in predicting variation in postnatal development were examined. Fetal heart rate and variability were measured longitudinally from 20 through 38 weeks gestation (n = 137) and again at age 2 (n = 79). Significant within-individual stability during the prenatal period and into childhood…

Age differences in decision making indicate that children fail to anticipate outcomes of their decisions. Using heart rate and skin conductance analyses, we tested whether developmental changes in decision making are associated with (a) a failure to process outcomes of decisions, or (b) a failure to anticipate future outcomes of decisions.…

In this article, the authors explore the breadth and depth of published research linking dietary vitamins and minerals (micronutrients) to mood. Since the 1920s, there have been many studies on individual vitamins (especially B vitamins and Vitamins C, D, and E), minerals (calcium, chromium, iron, magnesium, zinc, and selenium), and vitamin-like…

Background: Little is known about mechanisms of genetic influence on panic, particularly in childhood. Cognitive theories of panic disorder highlight threatening interpretations of physical sensations, and increased awareness of such sensations. Specifically, anxiety sensitivity (AS) and heartbeat perception (HBP) have been associated with panic…

To better understand the origins of autonomic reactivity during marital interactions, this study examined the psychophysiological profiles of prototypically secure (vs. insecure) and deactivating (vs. hyperactivating) adults while they talked about areas of disagreement with their (pre)marital partners. Adults who idealized their caregivers…

The current state of health of the United States, including physical inactivity, dietary intake, and overall lifestyle habits is of concern for educators. Specifically, the health of the college population appears to be under-represented in health and wellness research. The purpose of this study was to evaluate a 15-week university wellness-based…

Background: Health science programs can be demanding and difficult for many students, leading to high levels of stress. High levels of stress can have a negative effect on students and subsequently the practicing clinician. Research suggests that yoga, humor, and reading are simple, effective methods to help reduce stress. To date no research…

The effectiveness and safety of a group aquatic aerobic exercise program on cardiorespiratory endurance for children with disabilities was examined using an A-B study design. Sixteen children (11 males, five females) age range 6 to 11 years (mean age 9y 7mo [SD 1y 4mo]) participated in this twice-per-week program lasting 14 weeks. The children's …

The role of fitness in preventing coronary heart disease is explored. Research on high-density lipoprotein, which has been found to be one of the most critical determinants of risk, is reviewed. The relationship between fitness, high-density lipoprotein, and coronary heart disease is assessed, and clinical implications are spelled out. (MT)

The physiologic and metabolic adjustments of the body to a single endurance exercise session are analyzed in terms of the respiratory system, the cardiovascular system, and oxygen delivery to the muscles. Patients with cardiorespiratory and neuromuscular diseases are compared to normal individuals. (Author/MT)

This review discussed the various mechanisms that have been proposed to be causative of the hyperventilation that occurs during heavy exercise. The humoral hypothesis and nonhumoral hypothesis and secondary factors are reviewed. (MT)

Investigated the effects of dieting and exercise on resting metabolic rate (RMR) in overweight women (N=10). Results showed that dieting lowered RMR by nearly double that expected on the basis of resulting weight loss; and that exercise caused RMR to rise to a level appropriate to prevailing body weight. (LLL)

HIV infection and highly active antiretroviral therapy (HAART) are associated with such metabolic disorders as AIDS wasting syndrome, metabolic dysregulation, and abnormalities of serum lipids. Adjunctive therapies (e.g., diet and antilipid therapy); risk factor modification (e.g., smoking cessation and blood pressure control); aerobic exercise;…
