Abstract
Generalizability theory was utilized to investigate the amount of variation associated with various facets in the assessment of skinfolds as suggested by the American Alliance for Health, Physical Education, Recreation and Dance (AAHPERD) Health Related Physical Fitness Test. The facets utilized were testers, instruments, and repeated trials. Results indicate that the variation associated with the tester, instrument, and trial facets was small. Components of variance and G coefficients indicate that skinfold measures vary little depending upon the tester, instrument, or trial used. Suggestions are made for accurate assessment of the skinfolds recommended in the AAHPERD Health Related Physical Fitness Test.
