Effects Of Short-Term, High-Force Resistance Training On High-Intensity Exercise Capacity., Patrick Abi Nader Dec 2010

Effects Of Short-Term, High-Force Resistance Training On High-Intensity Exercise Capacity., Patrick Abi Nader

Electronic Theses and Dissertations

The purpose of this study was to assess the effects of short-term high-intensity resistance training on time to exhaustion at maximal aerobic output. It was hypothesized that 2 weeks of training will induce improvements in performance at maximal aerobic output. Eighteen subjects participated in this study. Subjects were assigned to a control (n=8) or resistance training (n=10) groups. The resistance training group participated in 5 sessions of strength training over a period of 2 weeks on the leg press device. Both groups participated in pre and post intervention testing. After the intervention strength in the training group significantly increased (p=.00). …


Resistance Training Increases The Expression Of Ampk, Mtor, And Glut4 In Previously Sedentary Subjects And Subjects With The Metabolic Syndrome., Andrew Steven Layne May 2010

Resistance Training Increases The Expression Of Ampk, Mtor, And Glut4 In Previously Sedentary Subjects And Subjects With The Metabolic Syndrome., Andrew Steven Layne

Exercise has been considered a cornerstone of diabetes prevention and treatment for decades, but the benefits of resistance training are less clear. Nineteen non-diabetic subjects (10 metabolic syndrome, 9 sedentary controls) underwent 8 weeks of supervised resistance training. After training, strength and O2max increased by 10% in both groups. Percent body fat decreased in subjects with the metabolic syndrome. Additionally, lean body mass increased in both groups (p<0.05). Expression of glucose transporter protein-4 (GLUT4), the principle insulin-responsive glucose transporter, increased significantly in both groups. 5-adenosine monophosphateactivated protein kinase (AMPK) and mammalian target of rapamycin (mTOR) expression increased in both groups, indicating increased protein synthesis and mitochondrial biogenesis. Markers of insulin resistance measured by a euglycemic hyperinsulinemic clamp did not improve in subjects with the metabolic syndrome but increased significantly in control subjects (13%). Resistance training upregulates intracellular signaling pathways that may be beneficial for ameliorating the metabolic syndrome.


Differences In Bone Mineral Density Among Adolescent Female Tennis Players And Non-Tennis Players, Kevser Ermin Jan 2010

Differences In Bone Mineral Density Among Adolescent Female Tennis Players And Non-Tennis Players, Kevser Ermin

Electronic Theses and Dissertations

Approximately 10 million Americans have osteoporosis. Physical activity (PA) is an important step in preventing osteoporosis and is one of the major determinants of peak bone mass during adolescence. However, type of pa plays an important role when examining the effects of pa on bone mineral density (BMD). Purpose: 1) to determine the differences in BMD among adolescent female tennis players (TP) and non-tennis players (NTP); 2) to determine the differences in body composition (BC) between adolescent female TP and NTP; 3) to determine whether BC variables (weight, fat mass, and lean mass) were predictive of differences in BMD; and …
