The primary aim of this investigation was to evaluate the effect of training on the immune activation in skeletal muscle in response to an acute bout of resistance exercise (RE). Seven young healthy men and women underwent a 12-wk supervised progressive unilateral arm RE training program. One week after the last training session, subjects performed an acute(More)
To develop a global view of muscle transcriptional differences between older men and women and sex-specific aging, we obtained muscle biopsies from the biceps brachii of young and older men and women and profiled the whole-genome gene expression using microarray. A logistic regression-based method in combination with an intensity-based Bayesian moderated t(More)
Using a mouse model of lipoatrophic diabetes, we hypothesised that the chemokine (C–C motif) ligand 2 (CCL2)/chemokine (C–C motif) receptor 2 (CCR2) pathway contributes to hepatic macrophage accumulation and insulin resistance through induction of a chronic inflammatory state. Metabolic variables of insulin resistance and inflammation were characterised in(More)
The molecular mechanisms underlying the sex differences in human muscle morphology and function remain to be elucidated. The sex differences in the skeletal muscle transcriptome in both the resting state and following anabolic stimuli, such as resistance exercise (RE), might provide insight to the contributors of sexual dimorphism of muscle phenotypes. We(More)
OBJECTIVE To examine the independent contributions of objectively measured sleep duration and fragmentation on cardiometabolic risk accumulation in free-living obese adolescents. STUDY DESIGN Characteristics of metabolic syndrome (waist circumference, mean arterial pressure, fasting high-density lipoprotein cholesterol, triglycerides, glucose) were(More)
BACKGROUND The purpose of this study was to determine the sex-specific pattern of pediatric cardiometabolic risk with principal component analysis, using several biological, behavioral and parental variables in a large cohort (n = 2866) of 6th grade students. METHODS Cardiometabolic risk components included waist circumference, fasting glucose, blood(More)
Leptin, a protein hormone secreted by adipose tissue, plays an important role in regulating energy metabolism and the immune response. Despite similar extremes of adiposity, mutant mouse models, db/db, carrying spontaneous deletion of the active form of the leptin receptor (LEPR-B) intracellular signaling domain, and the s/s, carrying a specific point(More)
OBJECTIVE To examine the feasibility and potential benefits of using recumbent cross-training for nonambulatory adults with cerebral palsy (CP). DESIGN Observational. SETTING Clinical center for CP treatment and rehabilitation. PARTICIPANTS Significantly motor-impaired adults with CP (N=11) with a mean age ± SD of 36.3±13.2 years and Gross Motor(More)
BACKGROUND Pediatric weight management programs have substantial attrition rates, which have led to recommendations to assess readiness prior to enrollment. Both pretreatment readiness scales and behaviors, such as exercise, have been theorized to predict subsequent program completion. The purpose of this study was to explore the role of self-reported(More)
We assessed the influence of serum 25-hydroxyvitamin D (25[OH]D) and parathyroid hormone (PTH) concentrations on oral glucose tolerance, body composition, and muscle strength in older, nondiabetic adults who performed resistance exercise training (RT) while consuming diets with either 0.9 or 1.2 g protein kg(-1) d(-1). We hypothesized that individuals with(More)
