Advisor: Dr. Qin Lai

Major: Kinesiology and Exercise Science

Degree: Masters of Education

Background: Muscle fatigue is an exercise induced decline in the ability of muscles to produce force or power. Recent studies showed that decline in proprioception due to fatigue lead to an increasing risk of falls and injury. However, it was unknown whether fatigue-induced proprioception decrease affects skill acquisition and memory consolidation. Purpose: The aim of the study was to investigate the effects of local muscle fatigue on perceptual motor learning in …

Methodology For Performing Whole Body Pmhs Underbody Blast Impact Testing, And The Corresponding Response Of The Hybrid Iii Dummy And The Finite Element Dummy Model Under Similar Loading Condition, Karthik Somasundaram

Wayne State University Theses

In recent wars, the use of improvised explosive devices and landmines has dramatically increased as a tactical measure to counter armored vehicles. These weapons not only deform and damage the vehicle structure but also produce serious vertical deceleration injuries to mounted occupants. The reported injury patterns largely differ from those in an automotive crash and are often more severe than those in other vertical loading scenarios such as pilot seat ejection, helicopter crash, parachute landing and fall from height. High kinetic energy predominately along the principal vertical (Z-axis) over a short duration makes the underbody blast (UBB) loading conditions unique …

Football Helmet Fitment And Its Effect On Helmet Performance, Ron Jadischke

Wayne State University Theses

A method and system to objectively quantify helmet fitment was designed and developed. It measures the pressure between the energy-absorbing material in the helmet and the athlete's head. This system is also capable of measuring surface pressure during impact events. A volunteer-based field study was conducted to quantify how helmets were fitting athletes in a real-life setting. The helmets fit athletes in varying degrees of tightness and evenness. Most athletes (59%) had the highest pressures in the frontal area and 29% had the highest pressure in the occipital area. A large-sized helmet on the Hybrid III headform represented how most …

Contact Pressure Distribution Of Osteochondral Defects Of The Knee: Effects Of Non-Vertical Walls, Scott Ensminger

Wayne State University Theses

Purpose: To examine the relationship between well-shouldered osteochondral defects and

defects of different geometries by studying their effects on rim stress concentration and

load redistribution in the human knee.

Methods: Ten fresh-frozen cadaveric knees were mounted at 30° of flexion in a materials

testing machine. Digital electronic pressure sensors were placed in the medial and lateral

compartments of the knee. Dynamic pressure readings were recorded throughout the

loading and holding phases as each knee was loaded to 700N and held for 5 seconds.

Artificial defects were created in each knee to simulate well-shouldered defects and

beveled-defects. Loading was repeated for …

Psychological And Physiological Responses Of Males Viewing Same Gender Advertisements, Phil Dittmer

Wayne State University Theses

Body image has been a well established research topic in the field of sport and exercise psychology. However, most of the literature focuses on female body image and ignores male body image. It has been established by current literature that men react the same way as females when presented with pictures of the ideal body of the same sex; a negative body image affect. However, it is unknown in both females and males if this negative body image affect is a strong enough response to elicit a physiological stress response. This master's thesis serves as an explorative project to bridge …
