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

Human Movement Sciences & 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.

The Short-Term Effects Of Grade 1 And 2 Joint Mobilizations On Subject Pain Range Of Motion And Muscle Activity In The Pathological Lumbar Spine, Sean Hanrahan

Human Movement Sciences & Special Education Theses & Dissertations

The purpose of this study was to examine the short-term effects of Grades 1 and 2 posteroanterior joint mobilizations (JM) at the pathological lumbar spine on subject pain, range of motion (ROM), and muscle force. All subjects were determined to have sustained mechanical dysfunction of the lumbar spine of less than 48 hours as assessed through a standardized evaluation. Subjects were randomly assigned to a group; the control group received ice and stretching while the experimental group received JM in addition to ice and stretching. The JM's were performed at 3 consecutive lumbar segments surrounding the area of greatest discomfort. …
