The FITNESSGRAM health-related physical fitness test battery is the latest test battery sponsored by the American Alliance for Health, Physical Education, Recreation, and Dance. To ensure that the FITNESSGRAM test battery is an appropriate assessment tool, it is necessary to document reliability and validity evidence. Although there are documented univariate reliability estimates for the FITNESSGRAM test items, there are no reports of multivariate test battery reliability. The purpose of this study was to estimate the optimal test battery reliability of the FITNESSGRAM test battery among children in grades 3 through 6. The FITNESSGRAM was administered to children (N = 390) from one elementary school in both the fall and spring semesters of one academic school year. Test items included the 1-mile run/walk, the modified pull-up, the back saver sit-and-reach, the curl-up, the trunk lift, and the body mass index. Only children with complete sets of data (n = 352) were included in the reliability analyses. Canonic al correlation analyses were used to analyze the data and compute optimal reliability estimates for the FITNESSGRAM test battery. The optimal reliability estimate is the collective evaluation of the first canonical correlation coefficient (Rc1) and the total redundancy index (Rd Total) and can be used to determine if the FITNESSGRAM test battery reliably measures the norm-referenced health-related fitness scores of children in both the fall and spring. …
