OBJECTIVES To test the safety and effects of exercise conditioning on cardiorespiratory fitness, body composition, muscle strength, glucose regulation, and lipid/cholesterol levels. SUBJECTS Ten male adolescents with insulin-dependent diabetes mellitus (IDDM) and 10 adolescent nondiabetic (ND) subjects. DESIGN Pretest, posttest intervention trial with(More)
OBJECTIVE To examine the metabolic, physiologic, and hemostatic responses to action video game play in a group of young boys. DESIGN Comparison study. SETTING Laboratory of Clinical and Applied Physiology, University of Miami. PARTICIPANTS Twenty-one boys aged 7 to 10 years. MAIN OUTCOME MEASURES Blood pressure monitored before and during game play(More)
PURPOSE The purposes of the present study were to assess the effects of a 12-wk laboratory based aerobic exercise program on cardiopulmonary function, CD4 cell count, and physician-assessed health status among symptomatic pre-AIDS HIV-infected individuals (N = 28) and to assess the degree to which ill health was associated with exercise relapse. METHODS(More)
BACKGROUND Increased prevalence of adolescent obesity requires effective treatment options beyond behavior therapy. OBJECTIVE To see whether sibutramine reduced weight more than placebo in obese adolescents who were receiving a behavior therapy program. DESIGN 12-month, 3:1 randomized, double-blind trial conducted from July 2000 to February 2002. (More)
OBJECTIVE Exercise is the cornerstone of behavioral weight loss programs. The total volume of exercise needed to both promote weight loss and elicit health benefits has not been sufficiently investigated. The aim of this study was to examine the effects of two different volumes of walking 'metabolic fitness' exercise prescriptions, in combination with a(More)
Weight-loss interventions generally improve lipid profiles and reduce cardiovascular disease risk, but effects are variable and may depend on genetic factors. We performed a genetic association analysis of data from 2,993 participants in the Diabetes Prevention Program to test the hypotheses that a genetic risk score (GRS) based on deleterious alleles at 32(More)
Tennis requires skill, physical attributes, and strategy. Ball velocity and placement are two of the most important components in winning the faster-paced modern game. Although isokinetic testing has been used to evaluate physical characteristics and injury potential in tennis players, few studies have compared isokinetics and on-court performance. Such a(More)
This study was conducted to determine the effects of an aerobic exercise training program on subpopulations of lymphocyte phenotypes. Fourteen healthy but sedentary males, 18-40 years of age, were randomly assigned to either an aerobic exercise training or control condition. Aerobic exercise training consisted of three 45-minute sessions of cycle ergometry(More)
PURPOSE The present study examined the effects of exercise on physical and psychological variables in sedentary primigravidae (PRA). METHODS A total of nine women randomly assigned to an exercise (E) (mean age = 31.3 +/- 3.1 yr) and six subjects randomly assigned to a control (C) group (mean age = 27.8 +/- 3.1 yr) fulfilled all requirements for the study.(More)
Subjects performed 9 wk of isokinetic knee extensions twice weekly. Albuterol (N = 13) or placebo (N = 9) was administered for 6 wk; groups received 16 mg.d-1 of either treatment. Training consisted of three sets of 10 repetitions at 45 degrees.s-1. Data were collected at weeks 0, 6, and 9. Concentric and eccentric variables examined included: peak torque(More)
