The purpose of this investigation was to determine the test-retest reliability of four submaximum oxygen uptake (VO2) test protocols: (a) Modified Physical Working Capacity Cycle Ergometry, (b) Balke Ware Treadmill, (c) Canadian Step Test, and (d) Cooper Twelve-Minute Run/Walk in predicting the cardiovascular fitness of adults who were mentally retarded. The subjects worked in a sheltered workshop setting (N=17, M age=35 years, M IQ=54). The four submaximal VO2 tests were administered over eight sessions with test–retest reliability scores determined by administering each protocol separately and 1 week apart. An intraclass correlation coefficient revealed the following scores on each of the four protocols: Modified PWC Cycle Ergometry, R=.64; Balke Ware Treadmill, R=.93; Canadian Step Test, R=.95; Cooper Twelve-Minute Run/Walk, R=.81. Discussion includes considerations for administering predictor VO2 tests with persons who are mentally retarded. In this particular investigation the Balke Ware Treadmill Test (R=.93) and the Canadian Step Test (R=.95) revealed the highest reliability scores.

Burnout is a syndrome that has had a negative effect on the behavior of regular and special classroom teachers. The purpose of this investigation was to determine (a) whether special physical educators experience symptoms of burnout and (b) whether these symptoms fluctuate over time. Based on the results of this investigation, the subjects exhibited several symptoms that are related to the burnout phenomenon. Furthermore, these symptoms characteristically are high throughout the school year. It was concluded that special physical educator supervisors should design appropriate strategies to prevent or reduce these symptoms. Not only would this have a positive effect on teaching behavior but it would in turn improve student learning.
