Assessment Of Balance In Collegiate Cheerleaders: Is Implementing A Balance Training Program A Good Idea?, Caitlin Carroll

Honors Theses

Cheerleading has evolved immensely over the years. Gone are the days of simply shaking pom poms and yelling "GO TEAM!" Flips, twists, and prime athletic ability are what can be seen on the sidelines of any collegiate football or basketball game. Cheerleaders in general are assumed to have an above average level of balance, due to the nature of their training and sport. However, with these new skills comes the increasing risk for injury, and this risk may differ according to a cheerleader's position. As with any sport, cheerleading has specific positions. The cheerleaders that are put into the air …

The Effect Of The Female Athlete Triad On Performance: Both Physiologically And Psychologically, Constance Darlington

Honors Theses

The female athlete triad is a condition that is composed of an interaction of three separate disorders: low energy intake due to the presence of an eating disorder or disordered eating, menstrual dysfunction, such as, oligomenorrhea or amenorrhea, and osteoporosis. Separately, each disorder can affect performance; however, when the disorders are combined, the consequences are magnified. The female triad has a profound effect on an athlete's performance both physiologically and psychologically. The female athlete triad can affect any female athlete; however, it is more prevalent among the athletes that specialize in aesthetic sports or sports that emphasize leanness, for example, …

Prolonged Treadmill Walking In Healthy Participants With And Without The Use Of Foot Orthoses To Support The Medial Longitudinal Arch, Daisy K. Ng

Electronic Thesis and Dissertation Repository

In the research setting, instrumented treadmills are often used to study prolonged periods of walking. This thesis examines the effects of in-shoe foot orthoses on walking gait during prolonged periods of treadmill walking. The two types of foot orthoses investigated were: 1) a pedorthist hand-made orthotic with medial longitudinal arch (MLA) support and 2) a proprioceptive feedback-type orthotic designed to stimulate the intrinsic foot muscles of the MLA. The three kinematic variables observed over 60 minutes of intermittent treadmill walking were toe-out angle in the transverse plane, pelvic tilt angle in the sagittal plane, and trunk lean angle in the …

The Operational Load Carriage Context Of The Australian Army Soldier, Rob Orr, R. Pope, V. Johnston, J. Coyle

Rob Marc Orr

Military soldiers are required to carry loads as part of their occupation. These loads have led to injuries and even mortalities on the battlefield (Orr et al., 2011). Recent evidence suggests that the absolute loads carried by Australian Army soldiers are increasing (Orr, et al., 2010). The intent of this study was to investigate the loads can ied by Australian Regular Army soldiers on operations and the contexts in which these loads are carried.

Analytical Research Topics In Sport Management, Gi-Yong Koo

Graduate Theses and Dissertations

The field of sport management has grown tremendously as an academic discipline. Researchers have continuously discussed the scope and direction of research and the importance of the diversity of research design. There have been a significant number of studies examining the scope and direction of research over the past few decades such as: the lack of diversity in methodology; the lack of diversity in research focus; the lack of importance of power analysis; and the lack of diversity in topic areas. Embracing a variety of research designs is an absolutely necessary condition for the growth and credibility of sport management …

Load Carriage For The Tactical Operator: Impacts And Conditioning - A Review, Rob Marc Orr

Rob Marc Orr

Tactical operators are required to carry loads as part of their occupations. Carriage of these loads have been associated with causing physical injuries to the carrier and impairing their ability to perform occupational tasks. One potential means of negating these risks associated with load carriage tasks is through physically conditioning the carrier. Through use of the Frequency, Intensity, Time and Type (F.I.T.T.) formula this review explored the literature to determine the optimal conditioning stimulus to enhance the resilience of tactical operators required to perform load carriage tasks. It was determined that a conditioning stimulus of one load carriage session every …
