Evaluation Of Accelerated Plethysmography As A Measure Of Health And Fitness, Angela Marie Humble

Dissertations and Theses

Plethysmography is a technique used for measuring alterations in the volume of organs or limbs. Japanese researchers have developed a relatively new application of plethysmography (accelerated plethysmography) that uses information from the pulse wave measured at the fingertip to make inferences about health and fitness status. The instrument used to collect data -- the Precaregraph (accelerated plethysmograph) -- provides an accelerated pulse waveform and APG index, a mathematical representation of the waveform. It was the purpose of this study to evaluate the validity of the Precaregraph by examining the relationship between the APG index and previously validated measures of health …

Comparison Of Cardiovascular Disease Risk In Japanese Natives And Japanese Americans, Mayumi Takeda

Dissertations and Theses

This research examined potential differences in cardiovascular disease risk (CVR) in two groups: Japanese Natives living in Saga, Japan and Japanese Americans living in or near Portland, Oregon. It explored data gathered in an effort to build a theoretical framework for future studies. Environmental, nutritional, and lifestyle differences were also examined to compare the health status of Japanese residents in the two countries. The history of Japan from World War II to present, and the history of Japanese Americans both first and second generation, are discussed in the literature review.

Accelerated plethysmography (APG) is a technique which presumably allows the …
