title: Effects of repeated testing on the reliability of fitness scores of institutionalized mentally retarded individuals.
abstract: This study was designed to determine the effects of repeated trials on the reliability of physical fitness performance scores of 36, 12- to 20-year-old institutionalized mentally retarded children. They were tested 2 days a week for 5 consecutive weeks on the physical fitness criterion tests. The statistical analysis indicated no significant differences between trial scores on any variable over the 5 weeks. This lack of significance on all the physical fitness criterion tests suggests that administering all the trials on each item on one occasion is appropriate.
