In recent years, the academic standards of the collegiate student athlete have become a popular subject within the sociology of sport. In January 1983, the top competitive division of the NCAA voted to make more stringent the academic standards for participants in Division I intercollegiate sports. This was known as Proposal 48, and although the vote was 2 to 1 in favor of it, much criticism was also voiced. This study examines the relationship between the American College Testing Program (ACT) and actual grade point average (GPA) for 753 male and female athletes at the University of Utah during a 10-year period. A secondary purpose was to determine the predictive validity of a predicted GPA formula (PGPA) and high school grade point average (HSGPA) as estimates of actual GPA. Other purposes were to determine the correlation of ACT, PGPA, and HSGPA with regard to gender, race, and sport. Pearson product-moment correlations were utilized to establish relationships between ACT scores, PGPA, and HSGPA with actual GPA. A multiple correlation coefficient was computed and a regression equation was established. In addition, a cross-validation was performed on the existing data. Results indicated that an equation combining ACT and HSGPA is the best predictor for Caucasians, while HSGPA alone is the best predictor for non-Caucasians. Factors other than ACT scores appear to be better predictors of academic success for the student-athlete, thus casting doubt upon the validity of Proposal 48 for the NCAA.

Physical function is regarded as the cornerstone of healthy aging, and exercise is an important determinant of healthy aging. This study examined the feasibility and physiological (heart rate, blood pressure, blood lactate, and rate of perceived exertion) and psychological (enjoyment) response resulting from an acute progressive sled-push (SLP) exercise session using the novel XPO Sled Trainer in older adults and compared that with walking (WKC) condition. The exercise session comprised six exercise bouts at 75%, 85%, 100% (2×), and 125% (2×) of normal velocity with a 2-min rest between bouts. Thirty-six older adults were randomly allocated into either the SLP or WKC conditions. No adverse events were observed during the exercise session, and all participants completed the exercise protocol as prescribed. One-third of the participants in the SLP group reported minimal body discomfort. Significantly higher responses were observed for all physiological variables as the intensity of the exercise increased in the SLP group compared with the WKC group (p < .001). The SLP group presented a decline in enjoyment as the intensity of the exercise increased (during), but similar enjoyment level than the WKC group for the overall exercise session (p = .711). Our findings support the viability and safety of SLP exercise using the XPO Sled Trainer in older adults. Such exercise demonstrated an intensity-driven modality that may have potential to elucidate positive adaptations in the cardiovascular system of older adults with acceptable levels of enjoyment.
