Training Specificity And Functional Performance In Collegiate Cheerleaders, Carly Routman
Electronic Theses and Dissertations
INTRODUCTION: Competitive collegiate cheerleading requires participants to be conditioned for explosive powerful movements. Studies have shown cheerleading is associated with a high incidence of catastrophic injury (Mueller, 2009; Boden, 2005; Xu et al., 2021). In response to high injury rates, studies have recommended strength and conditioning requirements to decrease the likelihood of injury due to the lack of cheer-specific training (Jacobson et al., 2004). Although it has been recommended for cheerleaders to receive formal strength training, many schools do not provide these resources to their cheerleading teams. PURPOSE: The purpose of this study was to determine if there are differences …

Due to limited glycogen stores, carbohydrate (CHO) consumption during exercise is effective at improving performance in endurance events lasting longer than 90 minutes in duration. Recent research has established that CHO mouth rinsing may improve performance over shorter durations, independent of actual consumption. However, research is lacking in determining if an extended period of mouth rinsing has any additive benefit in conjunction with typical CHO beverage consumption over longer competition durations, where CHO ingestion/consumption is likely warranted. PURPOSE: Determine the effects of CHO mouth rinsing combined with consumption compared to CHO consumption alone on cycling performance. METHODS: Following …
The Effect Of Motivational General-Mastery Imagery On Reaction Time Performance And Heart Rate, William J. Bean Jr.
The Effect Of Motivational General-Mastery Imagery On Reaction Time Performance And Heart Rate, William J. Bean Jr.
Electronic Theses and Dissertations
Research suggests that imagery can reduce reaction time (Alikhani et al., 2001; Grouios, 1992; Hanshaw & Sukal, 2016; Iftikhar et al., 2018; Shanks & Cameron, 2000). Previous studies examining the imagery and reaction time relationship have almost exclusively focused on motor imagery. Additionally, a recent study by McNeil and colleagues (2019) concluded that imagery training improved decision time variables, but not overall reactive agility. Individuals may not be able to generate unpredictable stimuli during imagery. The purpose of this study was to examine the effects of motivational general-mastery (MG-M) imagery on reaction time and heart rate. Reaction time was measured …
