Injured Athletes' Preferences Regarding Source Of Emotional Support, Kristin Kutz 2014 Bowling Green State University

Injured Athletes' Preferences Regarding Source Of Emotional Support, Kristin Kutz

Honors Projects

Athletes often experience emotional distress as a result of an injury. Feelings of loss, decreased self-esteem, frustration, and anger are not uncommon. Athletic trainers (ATs) who work with injured athletes are focused on helping the progression of athletes' physical healing, but their role in helping athletes emotionally and psychologically is often unclear. There are twelve Athletic Training Education Competencies that the National Athletic Training Association requires to be taught to undergraduate AT students, one of them being psychosocial intervention and referral. However, little research has been done to define the exact role of ATs in this area, as well as ...

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: Barefoot running (BF) is popular in the running community. Biomechanical changes occur with BF, especially when initial contact changes from rearfoot strike (RFS) to forefoot strike (FFS). In addition, changes in lumbar spine range of motion (ROM), particularly involving lumbar lordosis, have been associated with increased low back pain (LBP). However it is not known how changing from RFS to FFS affects lumbar lordosis or LBP. Thus, the purpose of this study was to determine if a change from RFS to FFS would change lumbar lordosis, and/or decrease shock attenuation, and/or change comfort levels in healthy recreational ...


Examining Lower Extremity Range Of Motion And Movement Variability Chages Due To Focus Of Attention During Landing, Andrew Nordin, Janet Dufek 2013 University of Nevada, Las Vegas

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 ...

Osteochondritis Dissecans Development After Bone Contusion Of The Knee In The Skeletally Immature: A Case Series, Kevin G. Shea, John C. Jacobs Jr., Nathan L. Grimm, Ronald P. Pfeiffer

Kinesiology Faculty Publications and Presentations

Osteochondritis dissecans (OCD) is thought to be an acquired osteochondral disorder, and its etiology may be multi-factorial. Trauma, both acute and repetitive events, has previously been proposed as a potential cause for OCD development. We present two cases of skeletally immature males who developed a symptomatic OCD lesion following a femoral condyle bone contusion. These cases suggest that an acute traumatic event may lead to the development of OCD of the knee.


Women's Cycle Racing: Enduring Meanings, Shelley Lucas 2013 Boise State University

Women's Cycle Racing: Enduring Meanings, Shelley Lucas

Shelley Lucas

In this study, I explore the challenges associated with long distance women's road racing. Within the sport of cycling, road race distances for women and men differ greatly. I examine the meanings that these distances have acquired within women’s road racing, according to promoters/race organizers, athletes, and governing bodies, as based upon their experiences with well-known and historically significant women’s competitions, circa 1950s-1990s. Based upon this research, the three main ways that distance has taken on meaning in women's road racing are as follows: 1) women do not have the stamina, strength or speed to ...

Effects Of Ageing And Exercise Training On Postural Stability In Relation To Strength Ratios Of The Lower Limb Muscles, Zachary James Crowley-McHattan 2013 Southern Cross University

Effects Of Ageing And Exercise Training On Postural Stability In Relation To Strength Ratios Of The Lower Limb Muscles, Zachary James Crowley-Mchattan

Theses

The aims of the research presented in this thesis were to determine the relationships between the muscle strength ratios of the agonists and antagonists at the knee and ankle joints, and the measurements of postural control, and how these relationships were influenced by ageing and specific exercise programs. The outcomes of the research suggested that ageing differentially affected the two strength ratios of the lower limb and had a significant negative effect on postural control. Tai Chi exercise had a benefit on muscular strength of the thigh muscles however no effect on strength ratios or static postural control.
