An Analysis Of Strength Training Implementation In Ballet, Claire Hoover

Senior Honors Theses

Ballet, a style of dance that is known for its 180-degree external rotation, extreme precision, discipline, and aesthetics, is an athletic activity that is undertaken by many young people, particularly females. Although ballet has many athletic components, recent studies have shown there are a variety of weaknesses that impact its participants, including the female athlete triad, lack of lower extremity muscular strength, risk of injury, and overtraining. According to recent research, strength training, although not historically paired with ballet, could minimize ballet dancers’ deficiencies by increasing muscular strength and reducing risk of injury and incidence of the female athlete triad. …

Evaluating The Need For Return-To-Learn Concussion Protocols In High School Student-Athletes: An Integrative Review, William David Midgette

Doctoral Dissertations and Projects

Over a million high school students are estimated to sustain at least one sports-related concussion annually. Unfortunately, over a third of these student-athletes suffer from post-concussion syndrome, which leads to the question of whether student-athletes are allowed proper time to heal after a concussion or if more can be done to optimize concussion recovery. Proper and optimal recovery post-concussion encompasses both physical and cognitive rest. While concussion management has traditionally focused on the physical aspects of recovery, emphasis has shifted to the cognitive impacts of concussions. There is literature to support that cognitive rest is vitally important, if not equally …

Health Consequences Of Low Energy Availability In Females And Their Underlying Physiological Mechanisms, Grace Parry

Senior Honors Theses

Low energy availability (LEA) is a state in which energy intake is insufficient to support energy expenditure while maintaining energy balance, which has been shown to result in gastrointestinal distress, immunosuppression, reduced metabolic rate, menstrual dysfunction, diminished bone health, and impaired cardiovascular function in females. Alterations to the microbiome and mucosal lining may propagate gastrointestinal complaints and compromised immune function associated with LEA. The pathophysiology of LEA is otherwise largely driven by hormonal adaptations. Diminished production of thyroid hormones is known to contribute to reduced metabolic rate. Decreases in leptin and insulin and increases in ghrelin disrupt reproductive function through …

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.

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.

A Review Of Stretching Techniques And Their Effects On Exercise, Cassandra M. Bernhart

Senior Honors Theses

The role of flexibility in exercise performance is a widely debated topic in the exercise science field. In recent years, there has been a shift in the beliefs regarding traditional benefits and appropriate application of static stretching. Static stretching has previously been proposed to increase exercise performance and reduce the risk of injury, however recent research does not support this belief consistently and may even suggest conflicting viewpoints. Several types of stretching methods have also been promoted including proprioceptive neuromuscular facilitation (PNF) stretching, AIS, and dynamic, and ballistic stretching. The role of flexibility in exercise performance continues to be researched …
