Effects Of An Angled Starting Block On Sprint Start Kinematics, Nathaniel A. Brown Dec 2007

Effects Of An Angled Starting Block On Sprint Start Kinematics, Nathaniel A. Brown

All-Inclusive List of Electronic Theses and Dissertations

The purpose of the present study was to investigate the effects of an angled proto-type starting block on sprint start kinematics. The angled starting block rotates the foot medially at a 16 degree angle, which emulates the 16 degree angle of the ankle on the medial axis of the foot. This 16 degree should allow for the athlete to apply more force against the block, resulting in a higher velocity at take-off and a faster block clearance time. In the present study, six female collegiate sprinters were filmed and analyzed using the angled starting block and a standard starting block. …

Fabrication Of Ankle-Foot Orthoses Using Selective Laser Sintering Technology, Allison Kinney, M. C. Faustini, Richard R. Neptune, R. H. Crawford, S. J. Stanhope

Mechanical and Aerospace Engineering Faculty Publications

Passive dynamic ankle-foot orthoses (AFOs) are often prescribed to improve gait performance for those with various neuromuscular disorders. Designs and materials used for AFOs range from simple polypropylene braces to advanced custom carbon fiber dynamic AFOs that passively store and release mechanical energy during gait. AFO designs vary in the shape and length of the foot component as well as the stiffness and length of the tibial component, depending on the desired functional outcomes. However, the current fabrication technology is not ideally suited for refined customization of AFO characteristics to optimize performance, or for rapid lowcost, high volume manufacturing and …

Development And Analysis Of A Software Package To Quantify In Vivo Polyethylene Wear After Total Hip Arthroplasty, Allison Kinney, Catherine G. Ambrose Jul 2007

Development And Analysis Of A Software Package To Quantify In Vivo Polyethylene Wear After Total Hip Arthroplasty, Allison Kinney, Catherine G. Ambrose

Mechanical and Aerospace Engineering Faculty Publications

Since the first total hip arthroplasty (THA) in 1938, THA evolved and developed into one of the major concentrations of orthopaedic research. The typical hip implant device used today incorporates a femoral and an acetabular component that serve to replicate the anatomical and mechanical functions of the natural hip joint. However, several problems exist that can effect the function of the implant device. Wear in the polyethylene liner of the acetabular component of the total hip replacement device is known as one of the major factors that affects the longevity of total hip replacement devices. Both manual and computer-aided techniques …

Lower Extremity Motion Analysis Patterns During Various Foot-Landing Styles, Nelson Cortes Jul 2005

Lower Extremity Motion Analysis Patterns During Various Foot-Landing Styles, Nelson Cortes

Human Movement Studies & Special Education Theses & Dissertations

Walking, running, and jumping are considered essential human movement activities that occur on a daily basis. In every landing task, the lower extremity needs to dissipate and absorb the energy that is created by the landing height. In addition, more dissipation is normally needed when landing from higher jumps, which increases the work that needs to be done by joints, muscles, and bones in order to prevent injury. Great amounts of load during a landing have the potential to induce injuries, particularly in the ankle and knee complex. In many sports, such as soccer, basketball, football, and volleyball, there is …

Focal Temperature Change Facilitates The Peak-To-Peak Soleus Hoffmann Reflex And Muscle Response, Bentley Andrew Krause May 2002

Focal Temperature Change Facilitates The Peak-To-Peak Soleus Hoffmann Reflex And Muscle Response, Bentley Andrew Krause

All-Inclusive List of Electronic Theses and Dissertations

Objective: Cryotherapy is a widely used rehabilitative modality in sports medicine. Cooling joint tissues has been observed to facilitate active exercise following injury. Mechanisms effecting motoneuron recruitment during and following cryotherapy are presumed to be both local and central in nature.

Patellofemoral Joint Compressive Forces During Backward And Forward Running At The Same Speed, Hesham N. Alrowayeh

Rehabilitation Sciences Theses & Dissertations

A previous study found that the patellofemoral joint compressive force (PFJRF) during backward running was less than during forward running at free speed. Therefore, the purpose of this study was to compare the patellofemoral joint compressive forces during backward and forward running at the same speed. Ten runners (4 females, 6 males) between the age of 20-25 (X=22, SD=2) ran in backward and forward directions at the slow speed of 2.3 mph (1.0 m.sec-1). Using the inverse dynamic technique the knee extensor moment and PFJRF during the slow backward and forward running were calculated. Results showed that the …

Physiological Effects Of Varying Power Output In A Cycling Time Trial, Mark Alan Liedl

Human Movement Studies & Special Education Theses & Dissertations

During a bicycle time trial, varying power slightly to counter external conditions may result in improved performance [Swain, 1997], but it is not known if such power variations result in added physiological stress. Thus, the purpose of this study was to determine if variable power (VP) cycling produced greater physiological stress than constant power (CP) cycling of the same mean intensity. Eight trained male cyclists (age 28 ± 2 yr, mass 74.4 ± 2.3 kg, VO2max 4.24 ± 0.13 L•min-1, weekly training 277 ± 44 km) performed three 1 h ergometer trials. The first trial was performed …
