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)
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)
This study compared three different measures of central adiposity: waist-to-hip ratio (WHR), waist-to-height ratio (WSHT), and waist circumference with cardiovascular risk factors, including serum lipoproteins and blood pressure in overweight pre- (n = 115) and postmenopausal (n = 46) women. Premenopausal women had a mean age of 35.6 +/- 6.79 y and a mean(More)
This study sought to determine whether visceral adipose tissue (VAT) and/or its anthropometric surrogates could significantly predict health-related variables (HRV) in overweight Caucasian (CC) (n = 36) and African-American (AA) (n = 30) women. With the use of magnetic resonance imaging, findings showed significantly higher volume and area of VAT (P <(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)
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)
OBJECTIVE To compare plasma plasminogen activator inhibitor type 1 (PAI-1) levels and to examine the association of PAI-1 with visceral adiposity and other components of the metabolic syndrome in overweight and obese premenopausal African-American (AA) and Caucasian (CC) women. DESIGN Cross-sectional study. SUBJECTS 33 CC and 23 AA healthy, overweight(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)
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)
OBJECTIVE The purpose of this study was to determine the relationship between body mass index (BMI), waist circumference, and waist-to-hip ratio (WHR) with cardiometabolic variables that reflect the metabolic syndrome in overweight/obese premenopausal White, African American, and Hispanic women. METHODS Two hundred and thirty four young overweight/obese(More)
