Post-Concussive Syndrome In A Female Basketball Player: A Case Study, Sarah L. Strand

Health and Human Sciences Faculty Works

The objective of this case study was to identify the signs and symptoms of concussion and post-concussive syndrome in a collegiate, female basketball player, as well as her progress to becoming symptom free. The patient, a previously healthy, 21-year-old with no previous head injuries, experienced a concussion and continued to participate in her sport. Even though the athlete knew the risks of playing while symptomatic, she did not report her symptoms, and continued playing until the season ended. This case highlights that even when patients know the risks, they may be willing to overlook them to continue playing and it …

The Effects Of Static Stretching On Muscular Hypertrophy During A Resistance Training Program, Zachary A. Martin

Senior Honors Theses

Abstract

Studies have shown that static stretching right before physical activity can negatively affect performance. In regards to weight lifting, it has been shown that static stretching immediately prior to lifting can decrease the maximum amount of weight that can be lifted. This study was created in order to determine if static stretching immediately prior to weight lifting over the course of nine weeks would result in smaller gains in muscle size compared to those who did not static stretch immediately prior to lifting over the course of nine weeks.

Examining Lower Extremity Range Of Motion And Movement Variability Chages Due To Focus Of Attention During Landing, Andrew Nordin, Janet Dufek

Interdisciplinary Research Scholarship Day

Attentional focus (AF) has been explored among a variety of motor skills providing evidence that external AF promotes automaticity and enhanced performance [6]. External focus of attention is distinguished from internal focus such that external focus is directed toward movement effect rather than body movements [6]. Movement variability provides a means of assessing functional characteristics of the neuromotor system, where normal functioning is suggested to occur within optimal limits, while excessively high or low movement variability is indicative of system dysfunction [2,4,5]. Additionally, the ability of the motor system to vary, or broadly distribute, internal loads is thought to reduce …

Gender Differences In Frontal Plane Lower Extremity Kinetic Variability During Landing, Andrew Nordin

Interdisciplinary Research Scholarship Day

Investigations of human movement variability have been used as a
means of exploring neuromotor functioning, where performance variability is
thought to provide the system with flexibility and a mechanism for adaptation to
movement repetition [1,2,4,6]. Operationally, variability has been considered to
fall within optimal limits (Figure 1), while excessively high or low variability has
been implicated in injury susceptibility [1,2,4,6]. Landing has been explored
due to a high incidence of injury in athletic performance, as well as the ability
to easily control task demands through increases in landing height [3,4].
The purpose of this investigation was to evaluate changes in …

External Factors And Athletic Performance, Kimberly D. Dahl

Senior Honors Theses

The science behind athletic performance has progressed significantly with the advancement of technology and research of sport. The current review examines further the effects of several external factors on athletic performance. Factors were deemed external if they involved either variables out of the athlete’s control or an athlete’s conscious decision. Addressing playing environment, voluntary consumption of alcohol, sleep, a variety of emotions, and team environment contributes to a better understanding of the wide variety of factors that may influence athletic performance. The conclusions reveal ways in which awareness of external factors may impact overall performance.

Kinematic And Spatiotemporal Analysis Between Sprint Drills And Maximal Sprinting, Julianne Cappadona

PTHMS Undergraduate Publications

Purpose: To determine if any kinematic differences exist between two common sprint drills (A- and B-drills) and maximal sprinting. Methods: 12 collegiate sprinters (19.17±1.11 y/o) granted informed consent were filmed performing two 40-meter sprints, A-skips, and B-skips. Three-dimensional motion analysis tracked the coordinates of 24 reflective markers and resulting joint kinematics were computed. Results: Statistical analysis revealed that sprinting yielded a significantly lower maximum hip flexion (p=0.015) but a significantly higher minimum ankle angular velocity (p=0.012) and step rate (p=0.000) value than A-drills. When compared to B-drills, sprinting values were significantly lower in maximum hip flexion (p=0.047), minimum knee flexion …
