Body Composition, Muscular Performance, And Free Testosterone Following 12-Weeks Of Protein Supplementation And Resistance Training In Men Aged 35-55, Matthew Steven Stone
Body Composition, Muscular Performance, And Free Testosterone Following 12-Weeks Of Protein Supplementation And Resistance Training In Men Aged 35-55, Matthew Steven Stone
Graduate Theses and Dissertations
PURPOSE: The purpose of this study was to investigate the effects of 12 weeks of protein supplementation and Autoregulatory Progressive Resistance Exercise (APRE) training on measures of body composition, muscular performance, and free testosterone in middle-aged men. METHODS: Untrained males (n = 35; 43.3 ± 6.6 years) participated in this study. Lean mass (LM) and fat mass (FM) were measured via Dual Energy X-ray Absorptiometry (DEXA), while strength was measured utilizing one repetition maximum (1RM), endurance measured using maximum repetitions completed (REPS) at 75% 1RM for the bench and leg press, and free testosterone was measured using changes in serum …
Dehydration, Muscle Damage, And Exercise In The Heat: Impacts On Renal Stress, Thermoregulation, And Muscular Damage Recovery, Cory L. Butts
Dehydration, Muscle Damage, And Exercise In The Heat: Impacts On Renal Stress, Thermoregulation, And Muscular Damage Recovery, Cory L. Butts
Graduate Theses and Dissertations
Purpose: The purpose was to identify the combined influence of dehydration, muscle damage, and exertional hyperthermia on biological markers of acute kidney injury and renal function. We also investigated the effects of performing muscle damaging exercise during mild hypohydration on muscle damage biomarkers and muscular strength recovery. Methods: Eighteen recreationally-active males (age 24 ± 5 y, body fat 17.3 ± 6.2%) completed a familiarization visit and two experimental trials separated by ≥28 days. The two experimental conditions consisted of either euhydration (EU; maintaining hydration, -1.2 ± 0.8%) or hypohydration (HY; restricting fluid consumption for 24 hours prior to and during …
The Relationship Between Mental Health And Ultra-Running: A Case Study, Joshua Justin Cook
The Relationship Between Mental Health And Ultra-Running: A Case Study, Joshua Justin Cook
Graduate Theses and Dissertations
This instrumental case study sought to explore the relationship between ultra-running and mental health through the lived experiences of a single participant who self-identifies as an ultra-runner. Three research questions were used to explore this relationship; how did the individual decide to participate in ultra-running, what aspects of ultra-running impact the participant’s mental health, and how has engaging in ultra-running impacted the participant’s mental health? The case study utilized three semi-structured interviews, two participant observations, video documentary review, and journaling to answer these questions. A thematic analysis of the data revealed four essential themes; 1) Development of participation, 2) Promotes …
Determinants Of Hydration In Children: The Role Of Physical Activity And Parental Dietary Habits, Hyun-Gyu Suh
Determinants Of Hydration In Children: The Role Of Physical Activity And Parental Dietary Habits, Hyun-Gyu Suh
Graduate Theses and Dissertations
PURPOSE: The purpose of these studies was 1) to examine the factors that influence the water intake in children and 2) to identify the optimal time window to assess hydration status that would be equivalent to 24-hour urine sample in children. METHODS: Study 1: Data for 200 parents (age:3-13y, female:62%, BMI:28.4±7.0kg∙m-2) and 200 children (age:7.5±2.9y, female:44%, BMI:17.7±3.9kg∙m-2) were recruited. Subjects recorded their fluid and food consumption on the 2-day diary, and food data were analyzed by using the Nutrition Data System for Research (NDSR) program. Physical activity levels were assessed with the International Physical Activity Questionnaire (IPAQ). All urine samples …
Effect Of A Skating Unit On Fitness In Fifth Grade Students, Eric Lange
Effect Of A Skating Unit On Fitness In Fifth Grade Students, Eric Lange
Graduate Theses and Dissertations
The purpose of this quantitative study investigates the effect of a skating unit on factors of cardiovascular fitness, static balance, explosive power, and agility in fifth graders. Methods: During a 6-weeks skating unit (twelve lesson), seventy-one students (ages 10-12; M age = 10.34) participated during regularly scheduled physical education classes. Three separate classes served as control group (C) (n=19; 8 male; 11 female) and two experimental groups: roller skating (RS) (n=26; 11 male; 15 female) and inline skating (IS) (n=26; 10 male; 16 female). Control group had no access to roller or inline skates during class time of study. Control …
Survey Of Hydration Knowledge And Behavior In Youth Mountain Bike Teams, Natasha Brand
Survey Of Hydration Knowledge And Behavior In Youth Mountain Bike Teams, Natasha Brand
Graduate Theses and Dissertations
Many youth sports organizations recognize the importance of educating on hydration practices and awareness, although according to recent research current hydration education is not correlating to effective practices. PURPOSE: The purpose of this study was to assess and describe the hydration knowledge and behavior of student-athletes participating in competitive junior high and high school mountain bike teams, in order to substantiate further research. METHODS: A total of 133 male and female participants, ranging from 11-18 years were surveyed on their hydration knowledge and behavior. All participants were apparently healthy and were active members of a National Interscholastic Cycling Association (NICA) …
The Comparison Of Using The Preferred Or Non-Preferred Wrist When Measuring Physical Activity In College Students, Bryce Daniels
The Comparison Of Using The Preferred Or Non-Preferred Wrist When Measuring Physical Activity In College Students, Bryce Daniels
Graduate Theses and Dissertations
Introduction. People who participate in regular physical activity have a decreased risk of chronic diseases and premature death. A dramatic decrease of physical activity occurs from adolescence to young adulthood. With important implications to health, physical activity is an important behavior to measure. However, inconsistencies exist on how to measure physical activity. When using accelerometers, differences between the preferred or non-preferred wrist may result in different estimates of physical activity. Purpose. The purpose of this study was to compare the preferred and non-preferred wrist accelerometry measured physical activity using commonly used research accelerometers during structured daily college activities (Actigraph GT3x-bt …
Disordered Eating Risk And Body Image Dissatisfaction Of Division I Male And Female Cheerleaders, Christopher Blaszka
Disordered Eating Risk And Body Image Dissatisfaction Of Division I Male And Female Cheerleaders, Christopher Blaszka
Graduate Theses and Dissertations
The sport of cheerleading is growing both in the high school and college setting, however there is little research on cheerleaders specifically, both sideline and competitive. It is clear that while this sport does not benefit from being affiliated with the NCAA, the athletes are still at large risk for disordered eating and eating disorders, and are in need of more accurate screening and prevention methods. With the lack of cheerleading studies in general, there is an even larger scarcity of studies that focus on males in cheerleading. The current study aims to fill the gap in the research regarding …
