Chronic Training Load And Dorsiflexion Range Of Motion Throughout A Season In Professional American Soccer, Tristan L. Young

Electronic Theses and Dissertations

Soccer has an incredibly complex movement profile. Players experience various types of strains on their body from the requirement to land in awkward positions while maintaining the ability to quickly accelerate and decelerate. Dorsiflexion range of motion (DFROM) is of concern due to the movement profile and ball control that requires constant eccentric and concentric actions at the talocrural joint. With an American soccer season spanning across nine months these demands can contribute to overuse, which has been linked to restricted range of motion. Restricted DFROM and asymmetries have been identified as injury predictors, but their relationship to performance has …

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 …
