Wai Puna: An Indigenous Model Of Māori Water Safety And Health In Aotearoa, New Zealand, Chanel Phillips Ph.D. Apr 2020

Wai Puna: An Indigenous Model Of Māori Water Safety And Health In Aotearoa, New Zealand, Chanel Phillips Ph.D.

International Journal of Aquatic Research and Education

Māori (the indigenous peoples of Aotearoa, New Zealand) are intimately connected to wai (i.e., water) yet are overrepresented in New Zealand’s drowning statistics each year. On average Māori account for 20-24% of all preventable and non-preventable drowning fatalities, despite comprising only 15 percent of New Zealand’s population. Drowning remains a significant issue posing a threat to whānau (i.e., families) through premature death being imminent and whakapapa (i.e., genealogy) being interrupted. There is limited research that has examined Māori and indigenous understandings of water safety within the literature and limited studies that have investigated the issue of Māori drowning from a …

Use Of A Novel Whole-Body Imaging Approach To Predict Resting Metabolic Rates In Athletes, Nicole Vencil Apr 2020

Use Of A Novel Whole-Body Imaging Approach To Predict Resting Metabolic Rates In Athletes, Nicole Vencil

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Prediction of energy expenditure allows for calculation of appropriate energy requirements, which is especially important for athletes. Resting metabolic rate (RMR) is the greatest contributor to total daily energy expenditure (TDEE) and is typically measured via indirect calorimetry. Indirect calorimetry is not always available, which results in the need for predictive equations. Most predictive equations have been developed with participants resembling the general population and have not been found to be appropriate for athletes, as they may incorrectly predict RMR due to the unique differences of body composition between athletes and the general population. The purpose of the present study …
