A Comparison of Body Composition of Junior High School Girls in Physical Education Using Skinfolds and Bioimpedance Techniques. (Measurement)

Article excerpt

The purpose of this study was to replicate and extend the research previously conducted by Ballinger and Malone (2001) on the use of the Tanita Bioimpedance Scale in Physical Education classes, as an alternative to the two-site FITNESSGRAM skinfold technique recommended by AAHPERD and CIAR. Participants were junior high school girls in regular physical education classes during the spring semester. Complete data were available for 27 (seventh-and eighth-grade female students) volunteers, who were assessed both in the morning and after lunch on skinfolds (calf and triceps) and bioimpedance, on four different dates throughout the semester. The schedule was selected to check for sensitivity to changes in hydration and dietary intake before and after lunch, as this was an unknown factor regarding the sensitivity of the bioimpedance scale, and for the skinfolds two-site method. Analysis of variance between the impedance and skinfolds methods reflect no significant differences in percent fat from the two methods (p< .01). Time needed for assessment was similar, as reported by the physical education teacher, however, the girls were able to self-assess using the scale, but not using skinfolds. …
