Variability Of Practice And Strength Training Periodization: When Theories Collide, Katherine Lauren Streder
Variability Of Practice And Strength Training Periodization: When Theories Collide, Katherine Lauren Streder
Master's Theses
The primary purpose of this study was to examine whether variability of practice enhances neuromuscular adaptations when compared to traditional strength training. The secondary purpose was to investigate whether there was a difference in perception of exertion between the two strength programs. Forty one subjects (23 women and 18 men) were assigned to either the control group or one of two treatment groups by a blocked-random method. Subject's one repetition maximum (1RM) for the kettlebell press and leg press were measured at baseline, after 4 weeks of training, and after 8 weeks of training. The treatment groups completed 8 weeks …
Role Of Adenylyl Cyclase S674 In Central And Forearm Vasomotor Control, James Corkal
Role Of Adenylyl Cyclase S674 In Central And Forearm Vasomotor Control, James Corkal
Electronic Thesis and Dissertation Repository
This study examined the cardiac and vasomotor responses to submaximal handgrip exercise and beta-adrenergic control in carriers (n = 6) and non-carriers (n = 4) of a genetic variant of adenylyl cyclase 6 (AC S674). Rhythmic handgrip contractions (1 minute bout; 2 second contraction-relaxation period) were performed at three different intensities (20, 40, and 60% of maximal voluntary contraction force) to test the vasodilatory response to exercise. Additionally, two 5 minute infusions of isoproterenol (0.01 and 0.02 µg·kg-1·min-1 diluted in 5% dextrose) and one 10 minute infusion of propranolol (0.1 mg·kg-1 diluted in 0.9% saline) were …
Exercise Participation During Weight Loss On A High Protein – Low Carbohydrate Diet Plan In Females Aged 15-25 Years, Margaret Mobley-Meulman
Exercise Participation During Weight Loss On A High Protein – Low Carbohydrate Diet Plan In Females Aged 15-25 Years, Margaret Mobley-Meulman
Electronic Theses and Dissertations
Weight gain due to poor diet and lack of exercise is responsible for over 300,000 deaths each year (U.S. Department of Health and Human Services, 2010). Obese adults have an increased risk for serious health conditions including high blood pressure and cholesterol, type 2 diabetes, coronary heart disease, stroke, gallbladder disease, osteoarthritis, sleep apnea, respiratory problems, and certain cancers (National Cancer Institute, 2012). Participation in exercise can help control weight, strengthen muscles and bones, and reduce the incidence of cardiac events, stroke, hypertension, type 2 diabetes, colon and breast cancers, osteoporotic fractures, gallbladder disease, obesity, depression, anxiety, and delay mortality …
Surfing Injuries Requiring First Aid In New Zealand, 2007-2012, Kevin Moran, Jonathon Webber
Surfing Injuries Requiring First Aid In New Zealand, 2007-2012, Kevin Moran, Jonathon Webber
International Journal of Aquatic Research and Education
In an island nation such as New Zealand with easy access to surf beaches, surfing activities are very popular and, while generally perceived as a healthy form of outdoor recreation, they do have attendant risks. This study reports on nondrowning, surfing-related incidents that required medical first aid on beaches during five summer seasons from 2007-2012. Retrospective descriptive analysis of data from lifeguard first aid reports found that 16% (n = 1,327) of injuries were the consequence of surfing activity. More males than females were treated for surfing injuries (68% male, 31% female). Lacerations (59%) and bruising (15%) accounted for most …
The Influence Of Respiratory Muscle Training On Exercise Endurance 2013, Justin Vanderbeck
The Influence Of Respiratory Muscle Training On Exercise Endurance 2013, Justin Vanderbeck
Master's Theses
Exercise endurance in multiple populations has been shown to increase after bouts of respiratory muscle training (RMT) (Bailey, Romer, Kelly, Wilkerson, Dimenna & Jones, 2010; Brown, Sharpe, Graham & Johnson, 2008; Griffiths & McConnell, 2007; Kilding, Brown & McConnell, 2007; Laoutaris et al., 2012; Markov, Spengler, Stuessi, Boutellier & Knöpfli-Lenzin, 2001; Spengler & Boutellier, 2000; Stuessi, Spengler, Knöpfli-Lenzin, Markov & Boutellier, 2001; Volianitis et al., 2000). The use of resistance via respiratory muscle strength training (RMST) has been shown to produce greater increases in endurance than with no resistance, but the method of RMST that produces the greatest increases in …
The Role Of Appearance In Perceptions Of Personal Trainers 2013., Patrick R. Boerner
The Role Of Appearance In Perceptions Of Personal Trainers 2013., Patrick R. Boerner
Master's Theses
The field of personal training in the United States is believed to have begun in the late 1970‟s and the early 1980‟s (Brooks, 2004). Today, personal training is a healthy profession that, according to the United States Department of Labor and the Bureau of Labor Statistics (2012), is expected to grow 24% (60,400 jobs) between 2010 and 2020. In comparison, the Bureau of Labor Statistics (2012) predicts the average growth rate for all occupations within the U.S. to be only 14% during the same ten-year span. Rapid growth within the field of personal training has brought an increased scrutiny on …
Resistance Training Behaviors In College-Aged Women 2013, Melanie Kornblatt
Resistance Training Behaviors In College-Aged Women 2013, Melanie Kornblatt
Master's Theses
The purpose of this study was to develop an understanding of women’s training behavior in the weight room. A secondary purpose was to determine what their beliefs and perceptions were in regards to lifting weights. Participants were college-aged females ranging in age from 17-29 years. Observations of weight lifting activities were conducted during peak hours of operation (Mondays, Wednesdays, and Fridays from 3- 6pm) in the fitness facility. A total of 60 hours of observations were conducted over a period of four weeks. In addition to observations, two focus groups were conducted. Participants were divided into two specific groups: I …
The Effect Of Skeletal Muscle Mass On Basal Metabolic Rate In College-Age Males 2013, Chase Vaughn
The Effect Of Skeletal Muscle Mass On Basal Metabolic Rate In College-Age Males 2013, Chase Vaughn
Master's Theses
There are many misconceptions within the fitness community. One such misconception is that an increase in muscle mass will have a large increase in basal metabolic rate, yet this may not be the best way for successful weight loss. The purpose of this study was to determine the strength of the correlation between skeletal muscle mass and basal metabolic rate. The hypothesis tested was that basal metabolic rate is strongly correlated with skeletal muscle mass. The participants were college-aged males (n =17). Skeletal muscle mass (SMM) was estimated using the skin-fold circumference model (SFCM): SMM (kg) = Ht (0.00744 CAG2 …
The Effects Of Intermittent Isometric Fatigue On Concentric, Eccentric, And Isometric Torque, Robert W. Lewis Jr.
The Effects Of Intermittent Isometric Fatigue On Concentric, Eccentric, And Isometric Torque, Robert W. Lewis Jr.
College of Education and Human Sciences: Dissertations, Theses, and Student Research
Fatiguing intermittent isometric (ISO) muscle actions of the leg extensors have been shown to result in a similar percent (%) decline in torque for concentric (CON), eccentric (ECC), and ISO muscle actions. However, the effects of intermittent ISO fatigue of the forearm flexors on CON, ECC, and ISO torque, have not been established. The purpose of this investigation was to determine the effects of 50 maximal, intermittent ISO forearm flexion muscle actions on CON, ECC, and ISO torque. Twenty adults (10 men (mean ± SD age = 21.9 ± 2.3 years) and 10 women (mean ± SD age = 22.7 …
Too Much Puff, Not Enough Push? Surf Lifeguard Simulated Cpr Performance, Kevin Moran, Jonathon Webber
Too Much Puff, Not Enough Push? Surf Lifeguard Simulated Cpr Performance, Kevin Moran, Jonathon Webber
International Journal of Aquatic Research and Education
The purpose of this paper is to report on the technical competency of volunteer surf lifeguards to perform CPR on a manikin in light of their lifeguard experience, age, and gender. The CPR skills of surf lifeguards on patrol at the beginning of the 2010-11 summer season were tested on manikins by observation of CPR procedures and electronic recording of compression and ventilation skills. Almost all lifeguards (n=252) made the appropriate initial checks for responsiveness (98%). Compression skills were generally performed accurately with few technical errors (such as incomplete release). Most lifeguards (87%) over-ventilated the lungs (> 600ml) on each …
