The purpose of this study was to determine whether pre- postoperative increases in physical activity (PA) are associated with weight loss and health-related quality life (HRQoL) following bariatric surgery. Participants were 199 Roux-en-Y gastric bypass (RYGB) surgery patients. International Physical Activity Questionnaire (IPAQ) used categorize participants into three groups according their preoperative /1-year PA level: (i) Inactive/Active (<200-min/week/>or=200-min/week), (ii)...
A previous study (Grassi B, Gladden LB, Samaja M, Stary CM, and Hogan MC, J Appl Physiol 85: 1394–1403, 1998) showed that convective O 2 delivery to muscle did not limit uptake (V˙o ) on-kinetics during transitions from rest contractions at ∼60% of peakV˙o . The present aimed determine whether this finding is also true for involving higher metabolic intensities.V˙o were determined in isolated canine gastrocnemius muscles situ ( n = 5) 4 min electrically stimulated isometric tetanic...
MAGAL, M., M. J. WEBSTER, L. E. SISTRUNK, T. WHITEHEAD, R. K. EVANS, and C. BOYD. Comparison of Glycerol Water Hydration Regimens on Tennis-Related Performance. Med. Sci. Sports Exerc., Vol. 35, No. 1, pp. 150–156, 2003. Purpose To compare glycerol water hyperhydration rehydration tennis related skill agility performance. Methods Eleven male subjects completed two counter-balanced, double-blind trials. Each trial consisted three phases: 1) with or without (1.0 g·kg−1) over 150 min, 2) 120...
The aim of this study was to determine the prevalence metabolic syndrome at baseline and after 6 months lifestyle modification among obese adolescents referred a multidisciplinary weight management program.A total 165 were evaluated baseline, measurements repeated in 57 subjects who completed program. Metabolic defined as having three or more following: body mass index (BMI) >97(th) percentile, hypertension, low high-density lipoprotein cholesterol (HDL-C), hypertriglyceridemia, impaired...
Summary The aim of this study is to examine outcomes from MI Values, a motivational interviewing (MI) intervention implemented adjunctive obesity treatment. Adolescents ( n = 99; 73% African American; 74% female; mean body mass index [BMI] percentile 98.9 ± 1.2) were randomized receive two sessions or education control. All adolescents participated in structured behavioural weight management Baseline, 3‐ and 6‐month assessments anthropometrics, dietary intake physical activity obtained. Both...
The purpose of this study was to examine the changes in catecholamines (epinephrine [EPI] and norepinephrine [NE]), interleukin-2 (IL-2) a biomarker oxidative stress (8-isoprostane) healthy individuals who were exposed dual challenge (physical psychological stress). Furthermore, also examined possible relationships between (NE EPI) 8-isoprostane IL-2 following combined physical challenge. Seven male subjects completed two experimental conditions. exercise-alone condition (EAC) consisted...
This study evaluated preliminary physical fitness, activity, and blood lipid profile data obtained from overweight adolescents upon enrolling in a healthy weight management program following 6 months of participation. One hundred sixty-eight participants (13.4+/-1.8 years, 37.9+/-8.3 kg/m(2), 59.5% female 76.2% African-American) enrolled the program. The intervention addressed factors related to nutrition, other behaviors management. Sixty-four (38.1%) completed While there was no...
This study’s objective was to examine dietary and metabolic changes in obese adolescents who completed 6 months of participation an outpatient multidisciplinary weight management program (N = 67). Participants (75% African American, 66% female, mean age 13.7 years) 24-hour recalls underwent measurement anthropometrics fasting blood lipid parameters at baseline after participation. General linear models suggested that participants significantly reduced total energy, fat, saturated...
Abstract Background Irradiation of the heart during cancer radiotherapy is associated with a dose-dependent risk failure. Animal studies have demonstrated that irradiation leads to an inflammatory response within as well reduction in cardiac reserve. In current study we aimed evaluate whether biomarkers correlated changes function and reserve after for breast or lung cancer. Methods results We studied 25 subjects history without prior diagnosis cardiovascular disease failure, 1.8 years...
Habitual physical activity is an important component of successful weight loss programs for morbidly obese individuals. This study examined self-reported (PA) participation in relation to excess and body mass index (BMI) reduction among gastric bypass surgery patients (GBS). PA was hypothesized contribute both greater (% EWL) a BMI at 2 years postsurgery. measured via self-report 1585 GBS between 1988 2001. were assigned groups [PA (n = 1479)/no 106)] further stratified by presurgical [35-49...
To examine quality of life (QOL), physical activity (PA), and readiness (PAR) among gastric-bypass surgery (GBS) candidates.The SF-36v2, International Physical Activity Questionnaire, a stages-of-change measure assessed QOL, PA, PAR respectively across 2 presurgical visits.Increases in mental were observed visits. Sufficiently physically active participants reported significantly higher QOL than did insufficiently participants.Findings demonstrating positive changes PA as well the...
The objective of this study was to examine correlates weight-based teasing, self-esteem, and depression among 119 treatment-seeking obese African American adolescents aged 11 18 years. Body satisfaction examined as a potential mediator the association between teasing self-esteem depression. Study participants (mean age = 13.9 years; 72% female) completed measures evaluating depression, body satisfaction. measured using multiethnic figure rating scale measure overall with appearance. results...
