"Research is a way for me to engage myself in learning via a more hands on way. It creates a more involved approach to education by gaining knowledge and experience through active participation and critical thinking. I enjoy doing research for the very reason that it's not just learning out of a book in the classroom. With my research I am trying to answer my own questions and determine my own conclusions, in the pursuit of adding to the immense amount of knowledge already existing within academia."

Research Description

Evaluation of Metabolic Cost During Ergonomic Hand Drive Wheelchair Use
Our study will look at the metabolic cost, in terms of heart rate (HR) and oxygen consumption (VO2 - maximum volume of oxygen that a body can consume during intense exercise) while wheeling with an EHD wheelchair versus a conventional manual wheelchair. Oxygen consumption is what helps the body convert the food you eat to a usable chemical called ATP, which is necessary for the body's cells to do their jobs. VO2 will measure how efficient an individual’s cardiovascular system and skeletal muscles are when it comes to extracting and utilizing oxygen during activity (Buch, 2006). In addition VO2 measurements are evaluated to determine an individual’s cardiorespiratory fitness levels. Therefore, the more oxygen efficient an individual is, the healthier they will be. The focus of the study is to compare the metabolic cost between two different types of wheeling (EHD and manual wheeling) in healthy individuals. We strive to understand whether the EHD is a more effective and efficient way to wheel as opposed to standard manual wheeling. More efficiency in the system promotes better endurance, which in turn increases the overall health of the individual. If we can show EHD wheelchair propulsion is more energetically efficient than conventional wheelchair use, this will be a successful tool in the improvement of mobility and quality of life for wheelchair bound people. This study will help provide knowledge concerning the metabolic cost comparing two modes of wheelchair propulsion. The results may lead to an increase in quality of life by increasing mobility and access to recreational and occupational opportunities.
