The Effect Of A Pettlep Imagery Intervention-Based Pre-Performance Routine On Golfer's Short-Game Performance, Logan Baughman

College of Graduate Studies: Theses & Dissertations

Studies have suggested that imagery has a positive effect on performance in a variety of sports. The PETTLEP model (Holmes and Collins, 2001) includes the seven minimum elements sport psychologists incorporate into their imagery scripts. The PETTLEP model is the most comprehensive imagery model, thus providing the most functional equivalence. Golf is the interest of this study, with research stating that imagery has an overall positive impact on golf performance (Nicholls & Polman, 2005). However, studies involving the PETTLEP model have not been investigated thoroughly. There are several shots that have not been studied with the PETTLEP model, therefore this …

Cardiovascular Risk, Remote Ischemic Postconditioning, And Endothelial Ischemia-Reperfusion Injury, Brian A. Hemenway

Electronic Theses and Dissertations

Remote ischemic postconditioning (rIpost) is a potent vasculoprotective stimulus that is thought to reduce reperfusion injury associated with heart disease. However, certain animal models of cardiometabolic risk factors such as dyslipidemia, diabetes, and hypertension suggest the beneficial effects of rIpost to lessen reperfusion injury may be diminished. These findings have not been studied in clinically relevant humans. The aim of this study was to determine whether the protective effects of rIpost are reduced in the context of raised cardiometabolic risk in humans. Seven participants with raised cardiometabolic risk burden (age:57±7 years; BMI: 31±4kgm²participated in this 2X2 randomized cross-over …

Effects Of A Post-Activation Potentiation Warm-Up On Submaximal Parallel Back Squat Volume, Rating Of Perceived Exertion, Peak Velocity, And Peak Power, Carlton Wei

Cal Poly Humboldt theses and projects

Resistance training (RT) is effective for improving athletic performance, with specific training loads and volumes dictating the adaptations. A warm-up is necessary to safely and effectively engage in RT: typically with a low intensity aerobic activity, stretching, and movement specific potentiating exercises. Post-activation potentiation (PAP) acutely increases muscular power following a conditioning contraction, though limited research has assessed its use for RT. The purpose of this study was to assess how a PAP warm-up protocol affects volume, rating of perceived exertion (RPE), and peak velocity and power with 75%1RM in the barbell parallel back squat (PBS) exercise across 4 sets. …

The Effect Of Workload Reductions On Anaerobic Work During High Intensity Running, Taylor Keith Kennon

Cal Poly Humboldt theses and projects

Anaerobic capacity has implications in health and sport. Sprint interval training improves anaerobic capacity, aerobic factors, as well as performance. Optimal durations for taxing anaerobic capacity have been shown to be 60 seconds, and have been elicited using the Anaerobic Speed Test. In order to maintain this optimal duration for multiple sets, a decreasing workloads method must be used as fatigue increases following each set. These work-loading methods must be compared to determine which protocol allows for the maximum exercise volume to be achieved. The purpose of this study was to compare the effects of three different workload protocols on …

The Effects Of Kinesio Tape On Circulation And Healing: A Meta-Analysis, Stephanie A. Chuml

The tape that these athletes were wearing is called Kinesio Tape (KT). KT was made to resemble the skin, in that it is elastic like the skin and can be stretched and return to its original property (Kinesio Taping Method, 2013). Since KT has become more popular, the claims of what KT can do has risen. The purpose of this study was to perform a meta-analysis on the …

The Effects Of Limb Dominance On Cross-Education In A Four Week Resistance Training Program, Caitlin Wend

Masters Theses

Cross-education is known as the phenomenon of strength transfer from the trained side of the body to the untrained side of the body by unilateral resistance training. Research has shown that limb dominance has an effect on the amount of strength that is gained on the untrained side. Studies have found that there is a greater cross over effect in strength from the dominant side of the body to the non-dominant side of the body than vice versa. The present study examined this effect by taking 12 college females and splitting them into three groups: dominant training, non-dominant training, and …

The Addition Of A Concurrent Bimanual Task Influences Postural Sway And Walking Speed Performance And Prioritization Across All Ages, Derek Matthew Liuzzo

Theses and Dissertations

As individuals age, there is an increase in attentional demands, a heavier reliance on vision, reduction in efficiency of both tasks, and longer processing intervals causing greater dual task interference on postural sway and walking speed. While cognitive-motor interference has been investigated, the impact of adding a functional, manual task while balancing or during gait is poorly understood across all ages. The overall purpose was to examine the relationship between age and task automaticity in dual-task conditions with a functional bimanual task, and describe how age influences attentional prioritization strategies. Older adults demonstrated differences in single and dual task performance …

Psychosocial Predictors Of College Student Athlete Burnout And Engagement, Brigid Byrd

Wayne State University Dissertations

Purpose: The purpose of this study was to assess salient psychosocial predictors of both academic and athletic burnout and engagement in college student athletes. Method: One-hundred and seventy-nine male and female college student athletes were recruited from a Midwestern University to complete a questionnaire at one time point. Results: The prediction model for athlete burnout was statistically significant, F (4,174) = 16.41, p<.001, and accounted for approximately 27% of the variance. The prediction model for athlete engagement was also statistically significant, F (4,174) = 9.25, p ≤ .001, and accounted for approximately 18% of the variance. The prediction model for student burnout was statistically significant, F (6,172) = 3.79, p<.005, and accounted for approximately 10% of the variance. The prediction model for student engagement was not statistically significant. Conclusions: Athletes who felt misunderstood by their coach, felt their coach did not provide options and choices, and who felt their coach was not confident in their sport ability experienced symptoms of athlete burnout while athletes who felt understood by their coach, felt their coach provided options and choices, and who felt their coach had confidence in their sport ability, believed in their ability to accomplish their sport goals, felt engaged in their sport. Also, athletes who felt their coach was less friendly and supportive if they were not training and competing well, felt intimidated by their coach, and who felt their coach tried to control their free time and who also felt their teammates did not encourage them to study or did not make sure they got to class had high student burnout. Application: Coaches should aim to create an autonomy supportive coaching climate in which athletes feelings of autonomy are enhanced. Exploratory findings also suggest decreasing controlling coaching behaviors and increasing teammate academic social support may be important in thwarting feelings of student burnout in student athletes.

The Effect Of Intrinsic And Extrinsic Motivations On Health Behavior In College Students: A Systematic Review, Kristen Melendez, Sharon Jalene

AANAPISI Poster Presentations

When measuring the weight of individuals to create healthy lifestyle plans with proper diet and exercise it is alarming how many people follow even the MINIMUM requirement to live a long healthy life. Research has proven that even people who are aware that they are overweight will likely only have a short-lived maintenance of healthy behaviors. Therefore, both intrinsic and extrinsic motivations were examined in order to better understand the difference between the population who maintains healthy lifestyles and those whose healthy habits are not sustained. Methods: A systematic review process was used to filter and screen for applicable studies …
