Ancient And Recent Demographic Events Influence Mitochondrial Dna Diversity In An Immigrant Basque Population, Michael Christopher Davis
Ancient And Recent Demographic Events Influence Mitochondrial Dna Diversity In An Immigrant Basque Population, Michael Christopher Davis
Boise State University Theses and Dissertations
The Basques are an ancient people, considered by many anthropologists to represent the oldest extant European population. Because of this, they have been the subject of numerous sociological and biological investigations. The Basque Diaspora, a relatively recent demographic expansion of the Basque population, has until now been overlooked in molecular genetic studies. Samples were taken from 53 individuals with Basque ancestry in Boise, Idaho, and the mitochondrial DNA (mtDNA) sequence variation of the first and second hypervariable regions were determined. Thirty-six mtDNA haplotypes were detected in the sample. Comparing the genetic diversity in the Idaho sample with other Basque populations, …
Differences In Muscle Activation In The Lower Extremities While Performing Traditional Squats And Non-Traditional Squats, Christopher M. Scotten
Differences In Muscle Activation In The Lower Extremities While Performing Traditional Squats And Non-Traditional Squats, Christopher M. Scotten
Boise State University Theses and Dissertations
Purpose: To determine if muscle activation in the lower back and lower extremities differ when performing traditional squats compared to non-traditional (forward center of pressure on foot) squats. The erector spinae, hamstrings, quadriceps, adductor longus, gastrocnemius, and gluteus maximus muscles were monitored for differences in this study. There are several variations of the back squat and each variation may possibly target muscles differently. Determining if non-traditional squats leads to larger erector spinae muscle activation, which in turn may lead to more lower back fatigue and possible lower back injury is a major aim of this study. Participants: Thirteen healthy males …
Costs And Benefits Of Variable Nest Density In Burrowing Owls: Effects On Predation, Ectoparasites, Egg Yolk Hormones, And Productivity, Justin Lamar Welty
Costs And Benefits Of Variable Nest Density In Burrowing Owls: Effects On Predation, Ectoparasites, Egg Yolk Hormones, And Productivity, Justin Lamar Welty
Boise State University Theses and Dissertations
Nesting density in birds is influenced by a number of factors including food availability, predation, and breeding site availability. As a result of a species’ nesting density, individuals incur certain costs and benefits related to predation rates, parasite levels, and productivity. I evaluated hypotheses related to these costs and benefits in burrowing owls (Athene cunicularia hypugaea) that nested within the Morley Nelson Snake River Birds of Prey National Conservation Area in southern Idaho. I calculated territory overlap, an index of nesting density, of actual nests by creating a 200m radius buffer around each nest and measuring the percentage …
Effects Of Old Nest Material On Occupancy And Reuse Of Artificial Burrows, And Breeding Dispersal By Burrowing Owls (Athene Cunicularia) In Southwestern Idaho, Corey S. Riding
Boise State University Theses and Dissertations
This thesis comprises two chapters describing my investigations of the breeding ecology of burrowing owls (Athene cunicularia) in southwestern Idaho. The first chapter details two experimental studies where I examined the effects of old nest material, primarily mammal dung, on the occupancy and reuse of artificial burrows by burrowing owls in 2004 and 2005. For burrows that owls had not used previously for nesting, adding material from actual nests did not induce occupancy. Thus, old nest material does not appear to function as a cue for burrow suitability. Removing old material from burrows that owls had used for …
A Case Study On The Use Of Athletic Performance Strategies In An Elite Athlete’S Management Of Pancreatic Cancer, Brooke Elisabeth Harris
A Case Study On The Use Of Athletic Performance Strategies In An Elite Athlete’S Management Of Pancreatic Cancer, Brooke Elisabeth Harris
Boise State University Theses and Dissertations
In 2007, 11.7 million people in the United States were living with a cancer diagnosis. Specifically, 12 in every 100,000 Americans are diagnosed with pancreatic cancer each year. The five year survival rate of pancreatic cancer in the United States is only 5.6% (National Cancer Institute, 2007). In addition to traditional pharmacological treatments, physical activity has been increasingly used to help individuals successfully cope with cancer. One area that has not been studied extensively is the use of sport psychology techniques to help athletes cope with cancer. It is possible that these techniques, learned by elite athletes during their careers, …
An Examination Of Strength Training Practices In A Sample Of Varsity High School Athletic Programs In Idaho, Monica Lynn Reynolds
An Examination Of Strength Training Practices In A Sample Of Varsity High School Athletic Programs In Idaho, Monica Lynn Reynolds
Boise State University Theses and Dissertations
The use of strength training, or resistance training to improve athletic performance, is growing among athletes of all ages. Currently, Idaho possesses no rules, regulations, and/or guidance for varsity high school athletics and strength training. PURPOSE: The purpose of this research was to explore the current practices for varsity level high school athletes and strength training. Specifically, examined were: who designs and implements strength training programs for varsity high school athletes, what kinds of training activities they do for their programs, and whether the responsible party or emphasis of strength training changes depending on the gender of the athletes. METHODS: …
Hip Power Asymmetry In Older Adult Fallers And Non-Fallers, Lauren Grace Mcdonald
Hip Power Asymmetry In Older Adult Fallers And Non-Fallers, Lauren Grace Mcdonald
Boise State University Theses and Dissertations
The purpose of this study was to determine if a difference exists in hip power asymmetry between community-dwelling older adult fallers and non-fallers. Hypothesis: fallers would be more asymmetrical than non-fallers. Participants: 21 non-fallers (10 females, 11 males) and 18 fallers (14 females, 4 males) over the age of 65 (76.5 ± 6.9yrs). Method: Isokinetic peak torque during flexion, extension, abduction, and adduction at four velocities was recorded as measures of leg power. Asymmetry equaled the percent of power difference between each leg. Data analysis: Differences in age, physical activity, height, weight, and BMI were assessed …
Reproductive Failure And The Stress Response In American Kestrels Nesting Along A Human Disturbance Gradient, Erin Hennegan Strasser
Reproductive Failure And The Stress Response In American Kestrels Nesting Along A Human Disturbance Gradient, Erin Hennegan Strasser
Boise State University Theses and Dissertations
Human disturbance may be an influential environmental stressor that affects birds across life stages. I examined whether external and endogenous factors including habitat type, habitat quality and individual quality (hereafter quality), or human disturbance affect American Kestrel reproductive success in southwestern Idaho. Specifically, I was interested in how these factors lead to nest failure or abandonment. I also investigated whether elevated corticosterone (CORT) concentrations mediate the relationships among explanatory variables and nest failure. As nestling kestrels may respond to stressors differently from adults, I examined whether conditions experienced during the nestling stage affected nestling American Kestrel (Falco sparverius) hypothalamic pituitary …
Determining Intensity Levels For Selected Wii Fit Activities In College Aged Individuals, Joshua D. Grieser
Determining Intensity Levels For Selected Wii Fit Activities In College Aged Individuals, Joshua D. Grieser
Boise State University Theses and Dissertations
Introduction: Physical activity is important to the proper growth, development, and overall health of an individual. Current physical activity trends show declines in activity level throughout aging. To counteract inactivity many physical activity interventions have been implemented in different age groups and yet very little change in activity level has been seen. The Nintendo Wii® offers a popular technological intervention tool with its movement oriented game play. The physiological costs and intensity of the Nintendo Wii Fit® game have not been thoroughly researched, yet the Wii is being used as a physical activity tool in many arenas. Purpose: The purpose …
An Examination Of The Effectiveness Of An 8-Week Bikram Yoga Program On Mindfulness, Perceived Stress, And Physical Fitness, Zoe Louise Hewett
An Examination Of The Effectiveness Of An 8-Week Bikram Yoga Program On Mindfulness, Perceived Stress, And Physical Fitness, Zoe Louise Hewett
Boise State University Theses and Dissertations
Previous research has examined the effects of yoga on levels of mindfulness. The physical and psychological outcomes of participation in a Bikram yoga program have not been thoroughly researched, yet this type of yoga may be significant with regards to stress management and inactivity due to its unique method of practice. The purpose of this study was to observe the changes in the levels of mindfulness, perceived stress and physical fitness due to participation in an 8-week Bikram yoga program. It was hypothesized that participants would show improvements in mindfulness, perceived stress and physical fitness. Fifty-one males and females between …
