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

Human Movement Sciences 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 Effects Of Four Gymnastics Skills On Vertebral Column Hyperextension In Young Female Gymnasts, Tonia Mcclure Burke

Human Movement Sciences Theses & Dissertations

There is very limited information available on the effects of gymnastics skills on spinal hyperextension. Eleven young female gymnasts between the ages of 11 and 15 participated in this study. The subjects height and weight were taken then they were screened for musculoskeletal injuries, normal abdominal and back extensor strength, normal hip flexor and hamstring flexibility, spondylolisthesis, and scoliosis. Hyperextension of the spinal column was measured during normal standing, hyperextending the spine in standing, and during four different gymnastics skills, using the Peak5 motion analysis system. Each subject performed five acceptable trials of four different gymnastics skill including a back …
