Effect Of Diet Induced Weight Loss And Exercise On Hscreactive Protein In Sedentary Postmenopausal Women, Jennifer Donnelly
Masters Theses, 2010-2019
Cardiovascular disease (CVD) risk factors, such as increased body fat, dyslipidemia, and high sensitivity C-reactive protein (CRP) levels are intensified in postmenopausal women. CRP has been reported as an independent indicator of risk for cardiovascular events. CRP is affected by multiple factors such as age, race, body mass index (BMI), and physical activity level. The purpose of this study was to compare the effects of an exercise intervention on traditional (BMI, percent body fat, waist circumference, physical activity level) and non-traditional (CRP) risk factors for cardiovascular disease to a dietary intervention program in sedentary, postmenopausal women. Twenty apparently healthy postmenopausal …
The Relationship Between Physical Activity Recommendations And Diabetes Risk Factors In Pregnant Women, Kelly Mattran
The Relationship Between Physical Activity Recommendations And Diabetes Risk Factors In Pregnant Women, Kelly Mattran
Masters Theses, 2010-2019
BACKGROUND: Changes in maternal insulin sensitivity throughout pregnancy may help supply nutrients to a growing fetus; however, the changes may concomitantly increase the mother and child’s risk for diabetes and chronic diseases. Regular physical activity (PA) positively impacts precursors for diabetes, but the impact of PA throughout gestation is less studied. The purpose of this study was to examine the relationship between meeting PA recommendations and diabetes risk in pregnant women. METHODS: A total of 23 pregnant women were recruited for participation. Venous blood samples, questionnaires, and anthropometric measurements (height, weight, and hip/waist circumferences) were ascertained during a single session. …
Concurrent Aerobic Exercise Interferes With The Satellite Cell Response To Acute Resistance Exercise In Mhc I Muscle Fibers, Lyle W. Babcock
Concurrent Aerobic Exercise Interferes With The Satellite Cell Response To Acute Resistance Exercise In Mhc I Muscle Fibers, Lyle W. Babcock
Masters Theses, 2010-2019
Purpose: Concurrent training attenuates hypertrophy compared to resistance training alone, and does so in a fiber-type specific manner. The mechanism responsible for this ‘interference’ is unclear, and satellite cell physiology, an important hypertrophic factor, has not been examined within this context. Therefore, the purpose of this investigation was to assess the fiber-type specific satellite cell response to acute resistance, aerobic and concurrent exercise. Methods: Eight recreationally active college-aged males (23±1 yrs, 83.4±3.6 kg, 181±2 cm, and 48.5±1.6 ml/kg/min) performed 3 sets of 10 repetitions with a fourth set ≥ 10 repetitions at 75% of 1RM for both unilateral leg extensions …
