The Neuroprotective Effects Of Endurance Training On The Aging Brain, Katelyn Norton 2016 The University of Western Ontario

The Neuroprotective Effects Of Endurance Training On The Aging Brain, Katelyn Norton

Electronic Thesis and Dissertation Repository

Dysregulation of autonomic control often develops with advancing age, favoring a chronic state of heightened sympathetic outflow with parasympathetic withdrawal. However, the mechanisms of this age-related autonomic impairment are not known and may relate to alterations in brain structure (e.g. cortical atrophy) and/or altered neural function, particularly in regions related to the cortical autonomic network, namely, the medial prefrontal cortex (MPFC), insula cortex (IC), and hippocampus (HC). Exercise exerts beneficial effects on brain structure and, in the case of cognition, neurologic function; however, how exercise affects regions of the brain related to autonomic function are not known. This ...


Exercise To The Rescue: An Analysis Of Altered Metabolic Gene Regulation Post-Exercise In Lean And Obese Individuals, Brandon Mudd 2016 Western Kentucky University

Exercise To The Rescue: An Analysis Of Altered Metabolic Gene Regulation Post-Exercise In Lean And Obese Individuals, Brandon Mudd

Honors College Capstone Experience/Thesis Projects

The skeletal muscle of obese individuals exhibits a depressed ability to metabolize fats. Exercise training is thought to rescue this dampened ability to metabolize fats; mediated by a coordinated increase in the expression of a network of genes that regulate metabolism and fuel utilization. The purpose of this study is to determine the exercise-induced regulation of metabolically important genes in lean and obese individuals. Muscle biopsies (one pre-exercise/baseline and one immediately post-exercise) were obtained from 4 lean (BF% 24.4 ± 5.5; 23.5 yrs ± 1.9) and 13 obese (BF% 39.7 ± 2.4; 26.1 yrs ± 2 ...

The Physiological Responses To Cycling Stress., Moriah Larsen

Skyline - The Big Sky Undergraduate Journal

Background: As the intensity of exercise increases, the risk of incidences for exertional heat illness (EHI) continues to climb. The National Athletic Trainers Association (NATA) has set an official position statement; stating a “gold standard” for obtaining core body temperature is via rectal thermometry. It has been reported that other field-expedient methods of obtaining core body temperature (oral, axillary, tympanic, temporal) are invalid or unreliable sources after intense exercise in hot temperature regions. Purpose: To determine if a relationship exists between rectal temperature measurements and tympanic temperature measurements during intensive long bouts of exercise. Design: Controlled Laboratory Study. Setting: Human ...

Older Women’S Muscle And Gait Response To A Bout Of Exercise Differs By Physical Activity Level, Jocelyn F. Hafer, Katherine A. Boyer

UMass Center for Clinical and Translational Science Research Retreat

Changes in gait are a consequence of aging and likely contribute to knee osteoarthritis (OA) incidence. Decrements in muscle function with age, including muscle power and fatigue resistance, may contribute to changes in gait and, subsequently, knee OA. Examining the impact of habitual physical activity (PA) on gait mechanics and muscle function may provide insight for interventions to modify knee OA risk. As knee OA affects women at greater rates than men, the current study focused on older women. The aim of this study was to determine if older women with different levels of habitual PA experienced the same effect ...

Is Low Level Laser Therapy Effective For The Treatment Of Delayed Onset Muscle Soreness, Rachel Deppa 2016 The College at Brockport

Is Low Level Laser Therapy Effective For The Treatment Of Delayed Onset Muscle Soreness, Rachel Deppa

Senior Honors Theses

This study was centered on low level laser therapy (LLLT) and its effects on delayed onset muscle soreness (DOMS). DOMS is an inflammatory response in muscle tissue characterized by pain, stiffness, and fatigue in the muscle post-exercise. DOMS results from bouts of eccentric exercise (the lengthening phase of muscle contraction). Symptoms usually reach their peak intensity between 24 and 72 hours post-exercise and subside within 5-7 days. LLLT is a type of therapeutic modality which is used to treat body dysfunctions by introducing light energy into the body. LLLT has been gaining popularity as a new treatment for DOMS, but ...


Is Low Level Laser Therapy Effective For The Treatment Of Delayed Onset Muscle Soreness, Breanna Fortney 2016 The College at Brockport

Is Low Level Laser Therapy Effective For The Treatment Of Delayed Onset Muscle Soreness, Breanna Fortney

Senior Honors Theses

Delayed Onset Muscle Soreness (DOMS) is a phenomenon that is experienced frequently in the active population. As the name implies, the onset of muscle soreness occurs at a point in time long after the bout of exercise was performed. DOMS may hinder athletic performance through decreases in strength and range of motion (ROM) and may cause considerable pain upon movement. The goal of this paper is to investigate different therapeutic modalities as treatment for DOMS and determine which intervention produces the most desirable results by way of treating the signs and symptoms associated with delayed onset muscle soreness.
