An Exploratory Biomechanical Analysis Of The Side-To-Side Swing Patterns Of Three Skilled Switch Hitters, Francesca Marie Castellucci
An Exploratory Biomechanical Analysis Of The Side-To-Side Swing Patterns Of Three Skilled Switch Hitters, Francesca Marie Castellucci
Master's Theses
The ability to successfully switch hit, or hit a baseball from both sides of the plate, requires a great amount of practice and coordination bilaterally. This study used three-dimensional kinematic and kinetic data to examine the swing patterns of skilled switch hitters in baseball. Three male minor league and division I collegiate switch hitters participated. Subjects stood on force plates and hit baseballs off a tee while their swings were recorded with a three-dimensional optical motion capture system. Each subject performed twenty total swings, ten from the right and ten from the left. The swings were digitally analyzed and the …
Effects Of Chainring Design On Performance In Competitive Cyclists, Christiane Rose O'Hara
Effects Of Chainring Design On Performance In Competitive Cyclists, Christiane Rose O'Hara
Master's Theses
The development of noncircular chainrings to improve cycling performance has been in progress since the 1980’s and continues apace. The aim of this study was to compare performance time and physiological responses in cycling using a standard circular chainring versus a noncircular chainring developed in 2005: the Rotor Q-Ring. Eight competitive male cyclists were pre-tested using the original circular chainrings and also on the initial week of testing. The intervention consisted of cycling with Rotor Q-Rings for four weeks. Post-testing occurred with the original chainrings for the final week of testing. Testing consisted of a maximal or submaximal graded exercise …
A Novel Exercise Device For Users In Wheelchairs: A Study Of Abdominal Muscle Activation, Rebecca Jo Campbell
A Novel Exercise Device For Users In Wheelchairs: A Study Of Abdominal Muscle Activation, Rebecca Jo Campbell
Master's Theses
This study evaluates the use of a wheelchair balance board. The balance board was created as a sensory stimulation tool for users with various disabilities. It was originally designed to create vestibular stimulation for the person after they were loaded on. This study was used as a way to test if the balance board could be used for other things such as physical therapy and exercise. Ten able-bodied individuals were used to show the functionality of the device. They were asked to perform six different abdominal exercises while the muscle activity of their rectus abdominis and external obliques was measured …
Impact Of Exercise On Brain Responses To Visual Food Cues: An Fmri Study, Nero Erezi Evero
Impact Of Exercise On Brain Responses To Visual Food Cues: An Fmri Study, Nero Erezi Evero
Master's Theses
On the basis of a strong body of data, the Institute of Medicine currently recommends at least 60 minutes of exercise per day to prevent body weight gain overtime. Previous studies have shown that there is no compensatory increase in food intake with this dose of exercise. Ultimately, the brain decides whether to alter food intake. Surprisingly, no published studies have assessed the impact of exercise on brain activation. Using functional magnetic resonance imaging (fMRI) and an appetite questionnaire, we investigated the effects of a single bout of aerobic exercise on brain responses to visual food cues and subjective appetite …
