Comparison Of Carotid, Brachial, And Popliteal Intima Media Thickness Among Sedentary And Physically Active Subjects Between 40 And 60 Years Old, Amanda Robinson May 2011

Comparison Of Carotid, Brachial, And Popliteal Intima Media Thickness Among Sedentary And Physically Active Subjects Between 40 And 60 Years Old, Amanda Robinson

Masters Theses, 2010-2019

The purpose of the current study was to determine the effect of long term versus recent training on intima-media thickness (IMT) and if this effect is localized in the vascular beds of the tissues directly involved in the activity. Thirty-four male subjects (aged 49.69 ± 6.48 years) were recruited and divided into the following groups: sedentary (SE), recent aerobic exercisers (RE) or long-term aerobic exercisers (LE). Carotid, brachial, and popliteal artery IMT was measured using B-mode ultrasonography. Diet, physical activity, and C-reactive protein (CRP) were measured as well. Carotid IMT was not significant (p=0.974) between the groups, with SE values …


Effect Of Diet Induced Weight Loss And Exercise On Hscreactive Protein In Sedentary Postmenopausal Women, Jennifer Donnelly May 2011

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 …


Influence Of Estradiol And Exercise On Foot Laxity, Ankle Laxity, And Plantar Loading In College Athletes, Kristina Teri Silke May 2011

Influence Of Estradiol And Exercise On Foot Laxity, Ankle Laxity, And Plantar Loading In College Athletes, Kristina Teri Silke

Masters Theses, 2010-2019

As female participation in athletics has increased, it has become apparent that sex differences exist in sports-related injury types and frequencies. The purpose of this study is to examine the effects of exercise and the sex hormone estradiol on sex differences in foot and ankle laxity and plantar pressure. We measured serum estradiol, pre- and post-fatigue ankle and toe laxity, and pre- and post-fatigue plantar pressure in 47 subjects (34 female, 13 male) once a week for 12 weeks. We compared laxity and plantar pressure in females not using oral contraceptive (NOC) to females using oral contraceptives (OC) and males. …
