Comparison Of Landing Biomechanics Between Different Competitive Levels Of Irish Dance, Jade Shields
Comparison Of Landing Biomechanics Between Different Competitive Levels Of Irish Dance, Jade Shields
West Chester University Master’s Theses
Abstract
Objectives: To determine differences in lower limb landing biomechanics and lower extremity function scale scores between champion levels, in young female Irish dancers.
Design: Cross-sectional.
Setting: McDade-Cara School of Irish Dance
Participants: 12 Open Champion (OC) level female Irish dancers (11.9 ± 3.37 years) and 9 Preliminary Champion (PC) Irish dancers (13.5 ± 3.37 years) performed the landing error scoring system test (LESS), and completed the lower extremity functional scale (LEFS) and a descriptive data questionnaire
Main outcome measures: LESS scoring sheet and LEFS PRO
Results: No significant differences found between OC and PC levels on …
Simulation Of A Rat Muscle-Tendon Unit With Hill-Type Model Dynamics And The Study Of Viscoelasticity In A Collagen Molecule Via Molecular Dynamics, Veronica Siko
West Chester University Master’s Theses
The field of biological science has established that tendons transfer muscular forces to adjacent bones, but there is a dearth of information about the underlying physical principles of these interactions and how the property of viscoelasticity (displayed in tendons as a difference in mechanical response to stress with differing stretching rates) is encompassed in the collagen of tendons. This thesis details the results of concentric and eccentric contractions of the rat muscle-tendon unit (MTU) with and without viscoelasticity (concentric contraction requires active shortening of the muscle, while eccentric contraction requires active lengthening of the muscle) (Lovering & Brooks, 2014). Once …
