Importance of aerobic fitness in cardiovascular risks in sedentary overweight and obese African-American women.

Background: Whether the level of aerobic fitness significantly impacts cardiovascular disease (CVD) risks in healthy, nondiabetic, overweight or obese African-American women remains uncertain.

Objective: To examine the clinical and metabolic risk factors of CVD in nondiabetic, sedentary overweight or obese African-American women with varying degrees of aerobic fitness.

Methods: Forty-eight African-American women, with mean age of 43 +/- 4.

Aerobic exercise improves cardiorespiratory fitness but does not reduce blood pressure in prehypertensive African American women.

Objective: To determine the effectiveness of a 10-week aerobic exercise training intervention on blood pressure, cardiorespiratory fitness, and workload in African American women with prehypertension.

Design: After we obtained informed consent and medical clearance, each participant underwent baseline measurements, an aerobic exercise-training regimen, and postintervention assessments.

Setting: This investigation took place in Columbus, Ohio, on the campus of The Ohio State University.

A comparison of military circumference equations to skinfold-based equations to estimate body composition.

Unlabelled: Circumference-based military equations (CBEs) were compared with a skinfold-based equation (SBE) to estimate body fat.

Objective: We determined the correlation between CBEs and SBE, evaluated the efficacy of CBE methods, and examined the difference in methods to identify noncompliant personnel. Circumference and skinfold measurements were taken in sequential order for 1,191 male civil service employees (37.

Nonthermal ultrasound and exercise in skeletal muscle regeneration.

Objective: To determine whether continuous nonthermal therapeutic ultrasound (US) and low-intensity exercise (Ex) influence skeletal muscle regeneration after a standardized contusion injury in an animal model.

Design: Randomized controlled trial with blinded comparisons in a 2 x 2 factorial (US by Ex) design.

Setting: Animal care facility and exercise physiology biochemistry laboratory.

Maximal lactate steady state declines during the aging process.

Increased participation of aged individuals in athletics warrants basic research focused on delineating age-related changes in performance variables. On the basis of potential age-related declines in aerobic enzyme activities and a shift in the expression of myosin heavy chain (MHC) isoforms, we hypothesized that maximal lactate steady-state (MLSS) exercise intensity would be altered as a function of age. Three age groups [young athletes (YA), 25.

A Prospective Evaluation of the Effects of a 12-Week Outpatient Exercise Program on Clinical and Behavioral Outcomes in Patients with Epilepsy.

Purpose. We hypothesized that patients randomized to an exercise program would demonstrate a measurable improvement in behavioral outcomes with no adverse clinical outcomes, as compared with control patients.Methods.

Changes in concentrations of neuroendocrine hormones and catecholamines in dogs with myocardial failure induced by rapid ventricular pacing.

Objective: To describe neuroendocrine responses that develop in dogs subjected to prolonged periods of ventricular pacing.

Animals: 14 adult male hound-type dogs.

Procedure: Samples were obtained and neuroendocrine responses measured before (baseline) and after 3 periods of ventricular pacing.

Evaluation of a step-counter during treadmill walking in 7-12 year old African-American children.

The primary purpose of this study was to evaluate the accuracy of the Digiwalker step-counter in recording the number of steps by African-American children during level treadmill walking and the accuracy of the Digiwalker when placed inside a pouch at midline rather than when placed at midline of the thigh. A secondary purpose of this study was to examine the relationship between the number of steps and physiological response to walking. Study subjects were a sub-set of thirty-one children recruited from a larger study evaluating the effects of an after school program on cardiovascular risk factors in this population.
