Determining The Validity Of A New Cycle Ergometer Protocol For Estimating Vo(2) Max, James Allen Parrott

Human Movement Studies & Special Education Theses & Dissertations

The current American College of Sports Medicine (ACSM) submaximal cycle ergometer protocol has been evaluated by several researchers for its validity in estimating maximal oxygen consumption (VO₂max). It has been found that the ACSM protocol overestimates VO₂max by 28% on average (Swain and Wright, 1997). It is felt that the short stage duration, only 3 minutes, of the ACSM protocol is largely responsible for this overestimation. The new submaximal cycle ergometer protocol evaluated here utilizes a 6-minute stage in an attempt to reduce the overestimation of VO2max while increasing the overall test validity.

A Cross-Validation Of The Marshall University Step Test On College Males And Females Age 18-24, Mary Robin Hampton

Theses, Dissertations and Capstones

Positive health entails more than the absence of disease; it is a state of physical, mental, and social well-being (Hartung, Krock, Crandall, Bisson, & Myhre, 1993; Payne & Hahn, 1995). Physical fitness, as described by Francis (1987), is the potential for making adequate functional adjustments to increased metabolic demands. Cardiorespiratory fitness (aerobic fitness) is believed to be the single best indicator of physical fitness (Astrand & Rodale, 1985). The standard index of cardiorespiratory fitness is maximum oxygen uptake (VO^^), or the maximum rate at which oxygen can be consumed. VO2max is dependent upon the cardiovascular system’s ability to deliver blood …

Acute Blood Pressure Responses To Static And Dynamic Exercise: Racial Differences, Reuben Leon Wright

Theses and Dissertations in Urban Services - Urban Education

African Americans have a higher incidence of hypertension than other racial groups. Furthermore, some research suggests that normotensive individuals who exhibit exaggerated blood pressure (BP) responses to exercise may be at risk for future hypertension. This study sought to determine if normotensive African Americans exhibited exaggerated BP responses to static exercise or dynamic exercise relative to Caucasian Americans and Asian Americans. Thirty normotensive subjects participated from each of the three racial groups (15 males and 15 females). Subjects held 30% of maximal voluntary contraction (right knee extension) for 3 minutes, and BP was recorded during the third minute. On a …
