The Relationship Between Catecholamines And Lactate Concentration In Response To Exercise In Adolescents With Obesity, Vincent Vuong, Daniela Rubin
The Relationship Between Catecholamines And Lactate Concentration In Response To Exercise In Adolescents With Obesity, Vincent Vuong, Daniela Rubin
International Journal of Exercise Science: Conference Proceedings
Epinephrine is a catabolic hormone that increases metabolism through glycolysis and glycogenolysis. During exercise, accelerated glycogen and glucose breakdown is associated with increased lactate production. Previous studies show obesity (OB) decreases the epinephrine response during exercise potentially affecting glucose metabolism and lactate production. PURPOSE: To compare the epinephrine and lactate responses in adolescents with OB and adolescents with normal weight (NW) and to determine if changes in epinephrine and lactate concentrations are associated. METHODS: 12 adolescents with OB (9.2 ± 1.2 y, 39.9 ± 6.8% body fat) and 12 adolescents with NW (17.5 ± 4.6% body fat) completed …

Peak oxygen uptake (V̇O2peak) in a cardiopulmonary exercise test (CPET) is a strong predictor of morbidity, mortality, and quality of life. V̇O2peak in obese individuals is typically below the lower limit of normal (2 transport and utilization, i.e. aerobic deconditioning; or both. We hypothesized a modified CPET, to measure the fraction of maximum isokinetic power that can be supported by aerobic metabolism, will distinguish between adiposity and deconditioning effects on V̇O2peak. PURPOSE: To compare V̇O2peak and isokinetic neuromuscular performance in obese vs non-obese men. METHODS: A modified CPET with maximal (3 s) isokinetic cycling …
The Relationship Between Postural Control And Motor Proficiency In Children With Prader-Willi Syndrome And With Obesity, Alberto Garcia, Debra J. Rose, Daniela A. Rubin
The Relationship Between Postural Control And Motor Proficiency In Children With Prader-Willi Syndrome And With Obesity, Alberto Garcia, Debra J. Rose, Daniela A. Rubin
International Journal of Exercise Science: Conference Proceedings
Prader-Willi Syndrome (PWS) is a rare neurodevelopmental genetic disorder that can lead to obesity. Children with PWS exhibit poor motor skills and poor postural control. Postural control is defined as the ability to regulate sensory information to maintain a controlled, upright posture. Underdeveloped vestibular and proprioceptive systems, shown in PWS, may interfere with maintaining posture and performing fundamental skills that require effective sensorimotor integration. Obesity (OB) can also be negative to postural control and motor skill development. PURPOSE: This study determined the relationship between postural control and motor proficiency in children with PWS and those with OB but without …

Mechanisms that underlie adipose tissue remodeling to enhance metabolic health in response to exercise training remain inadequately understood. PURPOSE: We utilized mouse genetics and human GWAS to determine the impact of exercise training on mitochondrial DNA copy number, and interrogate the relationship between Esr1 and adipose tissue health. METHODS: We performed RNAseq on adipose tissue from 100 strains of inbred mice following exercise training and determined mitochondrial content by qPCR. We performed deep phenotyping of mice harboring conditional Esr1 overexpression selectively in adipose tissue. Adipose specific Esr1 overexpression and control mice were fed a high fat diet and …

Obese have a significantly higher Body Mass Index (BMI), which can be associated with poor nutritional intake and sedentary lifestyles. The ketogenic diet is a form of a dietary intervention which is often implemented for metabolic syndrome individuals such as obese populations. PURPOSE: The purpose of this study was to measure the effects of a ketogenic diet on anthropometrics, body composition, metabolic parameters, and psychological factors in young obese population. METHODS: Seven young obese participants (n=7, height (cm); 174.8 ± 10.9, weight (kg); 105 ± 20.7, BMI (kg∙m-2); 34.6 ± 4.8) completed an 8-week intervention with …
