Influence Of Traditional And Nontraditional Entries On Figure Skating Jumps, Bryanna L. Nevius

Undergraduate Review

The purpose of this study was to determine whether or not adding a non-traditional jump entry into a routine is more beneficial to the skater or if there is more value in performing the same jump with a traditional entry. Specifically, the study examined the kinematics of a non-traditional verses a traditional jump entry by looking at the angles of the hip, knee, and ankle joints at take-off and landing. Maximum jump height, airtime, and horizontal displacement were also examined. It was hypothesized that non-traditional entries would change jump kinematics when compared to the same jumps performed from traditional entries. …

Expandable Total Humeral Replacement In A Child With Osteosarcoma, Eric R. Henderson, Jidi Gao, John Groundland, Odion Binitie, G. Douglas Letson

Orthopaedics and Sports Medicine Faculty Publications

Case. A right-handed 8-year-old female patient presented with a conventional, high-grade osteosarcoma involving her right humerus; through-shoulder amputation was recommended. After consultation, total humerus resection with expandable, total humeral endoprosthesis reconstruction was performed with a sleeve to encourage soft-tissue ingrowth. At three-year follow-up she has received one lengthening procedure and her functional scores are excellent. Conclusion. Total humeral resection and replacement in the pediatric population are rare and although early reports of expandable total humeral endoprosthesis outcomes demonstrate high failure rates, this patient’s success indicates that expandable total humeral replacement is a viable option.

Gait Intervention For Improvements In Human Top Speed Running, Michelle Buechner

Graduate Student Theses, Dissertations, & Professional Papers

Between individuals faster sprinting speeds are achieved by applying greater stance average forces against the running surface. Recent evidence further indicates that elite level performers also strike the ground with leg kinematics that differ from those of non-elites and that these leg movements act to enhance the force transients occurring in the milliseconds following foot-ground impact. I investigated whether sprint performance could be enhanced through a short term gait intervention, consisting of 3 laboratory training sessions wherein subjects (n = 6) completed 5 high-speed runs on an instrumented force treadmill at 90% of their measured top sprint. The subjects received …

Acl Injuries In Female Athletes: Are Prevention Programs The Answer?, Brooke Chandor

Honors Theses

Around 400,000 people tear their anterior cruciate ligaments (ACLs) every year in the United States. The majority of these injuries occur during athletics, and most commonly to females. Their neuromuscular abilities, anatomies, and hormones put female athletes at a much higher risk of ACL injury than male athletes. The current gold standard of treatment, ACL reconstruction, is an imperfect technique at best. It leaves patients with much higher risk of both ACL reinjury and early onset of osteoarthritis. Prevention programs, aimed at reducing the neuromuscular risk factors in female athletes, have proved to effectively reduce the number of noncontact ACL …

Genu Recurvatum In Dance Training: Assessing And Addressing The Structural Deformity In Dancers, Anne Mercedes Mushrush

Undergraduate Honors Thesis Collection

Genu recurvatum is a medical condition in which the knee curves baac kwar d past the normal range of extension predominantly in the sagittal plane. Hyperextension can be attributed to extra laxity in the body, therefore the surrounding ligaments of the knee allow for the femur and tibia to be placed past a sagittal alignment of 180°, which is the possible knee extension of normal knee alignment. Genu recurvatum, medically viewed as a deformity, is desirable and considered a positive attribute in the dance world, especially classical ballet. Hyperextension also makes the line of the leg appear longer and straighter …

Intravascular Atp And The Regulation Of Blood Flow And Oxygen Delivery In Humans, Anne R. Crecelius, Brett S. Kirby, Frank A. Dinenno

Health and Sport Science Faculty Publications

Regulation of vascular tone is a complex response that integrates multiple signals which allow for blood flow and oxygen supply to appropriately match oxygen demand. Here, we discuss the potential role of intravascular ATP as a primary factor in these responses and propose that deficient ATP release may contribute to impairments in vascular control exhibited in aged and diseased populations.

Should Educators Be ‘Wrapping School Playgrounds In Cotton Wool’ To Encourage Physical Activity? Exploring Primary And Secondary Students’ Voices From The School Playground, Brendon P. Hyndman, Amanda Telford

Australian Journal of Teacher Education

Physical activity in school playgrounds has changed considerably over recent decades to reflect a climate of ‘surplus safety’. A growing culture of surplus safety can be attributed to a desire of parents and teachers responsible for children to protect school students from danger. The aim of this research was to examine students’ perceptions of playground safety influences on physical activity during school breaks from the perspectives of the ‘users’ of school playgrounds. Data collection consisted of seven focus groups (4 primary school & 3 secondary school) conducted across four schools (2 primary & 2 secondary). During this study, the focus …
