|Assessment of the Aerosport TEEM 100 portable metabolic measurement system.
||The present study evaluated the utility of a portable metabolic measurement system, the Aerosport TEEM 100. A total of 505 data points [242 from incremental (INC) and 263 from constant load (CL) exercise] were collected on 12 subjects (age = 25 ± 4 y...
|Attitudes toward physical activity in adolescents with Cystic Fibrosis: Gender differences with exercise training
||This study compared the attitudes of 16 adolescents (8 males and 8 females) with cystic fibrosis (CF) toward exercise and physical activity (PA) before and after a 6-week exercise program. Although the boys and girls had similar ages (12–18 years), t...
|Collagen Gene Variants Previously Associated With Anterior Cruciate Ligament Injury Risk Are Also Associated With Joint Laxity
||Background: Genetic association studies demonstrate a relationship between several collagen gene variants and anterior cruciate ligament (ACL) injury, yet the mechanism of these relationships is still unclear. Joint laxity is a heritable trait; incre...
|Early Detection of Type 2 Diabetes Among Older African-Americans
||The purpose of this research was to determine whether a group of African Americans who had no diagnosis of type 2 diabetes had elevated blood glucose levels and other risk factors indicative of type 2 diabetes. A convenience sample of 20 African Amer...
|The effect of exercise type on immunofunctional and traditional growth hormone.
||The purpose of this study was to compare the growth hormone (GH) response, including the immunfunctional (IF) GH response, between an acute bout of aerobic and resistance exercise in the same subjects. Ten cross-trained males (24.3 ± 1.2 years) perfo...
|Effects of acute aerobic and anaerobic exercise on blood markers of oxidative stress
||The purpose of this study was to compare oxidative modification of blood proteins, lipids, DNA, and glutathione in the 24 hours following aerobic and anaerobic exercise using similar muscle groups. Ten cross-trained men (24.3 ± 3.8 years, [mean ± SEM...
|Effects of Tai Chi Chuan on Insulin and Cytokine Levels in a Randomized Controlled Pilot Study on Breast Cancer Survivors
||Background-Tai Chi Chuan (TCC) is an integrative medicine mind-body practice with a physical activity component that has positive effects on aerobic capacity, muscular strength, and quality of life among cancer survivors, similar to the effects elici...
|Growth hormone (GH) release during acute and chronic aerobic and resistance exercise: Recent Findings.
||Exercise is a potent physiological stimulus for growth hormone (GH) secretion, and both aerobic and resistance exercise result in significant, acute increases in GH secretion. Contrary to previous suggestions that exercise-induced GH release requires...
|Impact of abdominal visceral fat (VAF), growth hormone (GH), fitness and insulin on lipids and lipoproteins in older adults
||We examined the relationship between abdominal visceral fat (AVF) and plasma concentrations of lipids and lipoproteins in 19 females (F) (not on estrogen) and 31 males (M) over the age of 60 (age = 66.8 years). In addition, the effects of growth horm...
|Impaired insulin secretion and increased insulin sensitivity in familial maturity-onset diabetes of the young 4 (insulin promoter factor 1 gene).
||Diabetes resulting from heterozygosity for an inacti¬vating mutation of the homeodomain transcription factor insulin promoter factor 1 (IPF-1) is due to a genetic defect of ß-cell function referred to as maturity-onset diabetes of the young 4. IPF-1 ...
|Intensity of acute exercise does not affect serum leptin concentrations in young men.
||Purpose: We examined the effects of exercise intensity on serum leptin levels.
Methods: Seven men (age = 27.0 yr; height = 178.3 cm; weight = 82.2 kg) were tested on a control (C) day and on 5 exercise days (EX). Subjects exercised (30 min) at the f...
|Phosphorylation of the JAK2- STAT5 pathway in response to acute aerobic exercise in young, healthy males.
||Growth hormone (GH) is a powerful stimulator of the Janus kinase 2 (JAK2)-signal transducer and activator of transcription 5 (STAT5) pathway. Acute exercise is a known stimulus for GH secretion.
Purpose: The purpose of this study was to determine th...
|Plasma protein carbonyl response to increasing exercise duration in aerobically trained men and women
||The purpose of this study was to determine the effect of aerobic exercise duration on plasma protein carbonyl concentrations, a marker of protein oxidation, in aerobically trained men and women. Eight men (age: 27 ± 4 years, V·O2peak: 4.09 ± 0.26 L ·...
|The Relationship Between Physical Activity and Perceived Health Status in Older Women: Findings from the Woman’s College Alumni Study
||Using data collected from the Woman’s College (WC) Alumni Study, the purpose of this study was to determine whether perceived health status is related to physical activity in older women. A multiple linear regression analysis was conducted to examine...
|Substrate oxidation is not altered during exercise in cystic fibrosis.
||Purpose: To determine substrate utilization and energy expenditure during maximal and submaximal exercise and recovery in adolescents with cystic fibrosis (CF) and healthy age-matched controls (C).
Methods: Ten clinically stable CF patients (four gi...
|Whole organ transplantation and glucose regulation.
||Pancreas transplantation has gained clinical acceptance since its initial application more than 30 years ago. A constellation of surgical, pharmacologic, and metabolic alterations occur with transplantation, particularly if pancreatic transplantation...
