Psychological Predictors Of Injury In Collegiate Cheerleaders, Alexander Marchand

Electronic Thesis and Dissertation Repository

According to the revised stress-injury model (Williams & Andersen, 1998), greater life stress predicts greater vulnerability to athletic injury, with this relationship being strongest among athletes exhibiting competitive anxiety, less social support, and non-adaptive coping skills. This study tested the validity of this model among collegiate cheerleaders, an injury-prone athlete group. Ninety-two collegiate cheerleaders recorded instances of injury over 12 weeks. Measures of life stress, competitive anxiety, coping style, social support, and previous injury were obtained. Heightened negative life stress did not coincide with greater injury. A positive stress-injury relationship was observed among cheerleaders reporting high avoidance coping. A negative …

Head-Trunk Coordination And Coordination Variability During Anticipated And Unanticipated Sidestepping, Sam Zeff

Masters Theses

INTRODUCTION: Sensory systems within the head provide us with rich perceptual information and may require complex control of the head during locomotion when changing direction. Head position in space is maintained by head on trunk motion as well as lower extremity kinematic modifications, such as increased knee flexion and increased stance time in order to facilitate shock attenuation and reduce vertical CoM displacement. It has been established that the body organizes its degrees of freedom of the trunk, pelvis and lower extremities differently during anticipated and unanticipated sidestepping, which raises the question of how these modifications affect head control during …

Cadence As An Indicator Of The Walk-To-Run Transition, Colleen Chase

Masters Theses

Humans naturally select a point at which to transition from walking to running when gradually increasing locomotor speed. This point is known as the walk-to-run transition (WRT). The WRT is traditionally expressed in terms of speed and is known to occur within a close range of 2.1 m/s, which is an accepted heuristic (i.e., empirically based, rounded) threshold value. Very little research exists defining the WRT in terms of cadence (steps/min) despite the fact that spatial temporal aspects of gait underlying the WRT include this parameter. Preliminary evidence suggests that the WRT may be associated with a cadence of 140 …

An Investigation Of Stress-Related Factors And Injury Occurrence In Division Iii Ice Hockey Athletes 2020., Christian Kiesel

Master's Theses

Many variables can factor into a student athlete sustaining an injury, but one of the most interesting is stress. The Stress and Injury Model is excellent in explaining how exactly history of stressors, personality, and coping mechanisms play a pivotal role in the stress response. If these three factors cause a negative stress response, then that will lead to an athlete becoming more likely to become injured. This study used 40 ice hockey players from a Division III NCAA institution. Each participant completed the Inventory of College Students’ Recent Life Experiences (ICSRLE) and Pittsburgh Sleep Quality Index (PSQI) every month …

Effect Of Sport-Specific Demands On Swimmer's Shoulder, Jordan A. Thielbar

Honors Thesis

Swimming is a unique sport in that the shoulders generate most of the propulsive force. Therefore, due to the large amounts of repetitive force, the shoulders generate during freestyle, swimmer’s shoulder is the most common injury among competitive swimmers. Freestyle biomechanics, muscular imbalances and posture all play a pertinent role in a swimmer’s risk for developing a shoulder injury during their swimming career. Swimmers typically develop large muscular imbalances between their dominant and nondominant shoulders due to several sport-specific demands including freestyle stroke mechanics, breathing, and body roll. These muscular imbalances alter a swimmer’s posture and freestyle biomechanics which eventually …
