PURPOSE Obesity may be a state of chronic oxidative stress. Oxidative stress may be the mechanism underlying the development of co-morbidities in obesity. This review provides a summary of the available evidence regarding systemic oxidative stress in young, older and clinical obese populations. METHODS Medline was searched for all available articles(More)
OBJECTIVES To examine obesity effects on outcomes following inpatient rehabilitation in patients following primary total knee arthroplasty or revision total knee arthroplasty. DESIGN Retrospective, comparative study. SETTING Fifty-bed, university-affiliated rehabilitation hospital. PATIENTS Obese (N = 139; body mass index >30 kg/m(2)) and non-obese (N(More)
OBJECTIVE To retrospectively examine the effects of sex and age on the inpatient rehabilitation outcomes of patients after total hip arthroplasty (THA). DESIGN Exploratory, retrospective study. SETTING A university-affiliated rehabilitation hospital. PARTICIPANTS Male and female THA patients (N=332) were stratified into age brackets (<65y, 65-84y,(More)
OBJECTIVE This study examined whether obesity affected inpatient rehabilitation outcomes after total hip arthroplasty (THA). RESEARCH METHODS AND PROCEDURES This was a retrospective, comparative study conducted using a computerized medical database derived from THA patients at a university-affiliated rehabilitation hospital (data from 2002 to 2005).(More)
This study examined the effects of 6 months of resistance exercise (RX) on basal and post-aerobic exercise lipid peroxidation (LIPOX). Men and women [n=62, mean (SD) age 68.4 (6) years] were divided randomly into either a control (n=16, CON), low-intensity training [LEX n=24; 50% one-repetition maximum (1RM), 13 repetitions/exercise], or high-intensity(More)
OBJECTIVE This multicenter study examined whether inpatient rehabilitation outcomes following total knee arthroplasty (TKA) were influenced by BMI. METHODS AND PROCEDURES This was a retrospective, comparative study conducted using a computerized medical database and medical records derived from TKA patients, at 15 independent rehabilitation hospitals (N =(More)
Mobility disability is becoming prevalent in the obese older population (> or = 60 years of age). We included a total of 13 cross-sectional and 15 longitudinal studies based on actual physical assessments of mobility in the obese older population in this review. We systematically examined existing evidence of which adiposity estimate best predicted mobility(More)
This investigation examined the effect of 6 months of high- or low-intensity resistance exercise on serum homocysteine and lipoprotein (a) levels in adults aged 60-80 years. Forty-three men and women completed the study protocol. Subjects were randomly assigned to a control (n=10), low-intensity (LEX, n=18), or high-intensity (HEX, n=15) group. Subjects(More)
OBJECTIVE To determine whether antioxidant (AOX) supplementation attenuates post-exercise oxidative stress and contributors to oxidative stress (inflammation, blood lipids) in overweight young adults. RESEARCH METHODS AND PROCEDURES This was a randomized, double-blind, controlled study. Overweight (BMI, 33.2 +/- 1.9 kg/m(2)) and comparative normal-weight(More)
OBJECTIVE To compare exercise-induced oxidative stress and levels of homocysteine and cholesterol in normal-weight and overweight older adults after resistance exercise (RX). RESEARCH METHODS AND PROCEDURES This interventional study was conducted at a wellness center. Forty-nine older adults (age range, 60 to 72 years) were stratified by BMI (<25 kg/m(2)(More)
