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. Subjects were junior high school females in regular physical education classes during the spring semester. Complete data was available for 27 (7th and 8th grade female students) volunteers, who were assessed both in the morning and after lunch on skinfolds (calf and triceps) and bioimpedance, on 4 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. ANOVA 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. Thus, feasibility of the BI scale was better than for skinfolds, considering self-assessment and teacher time. Following the last assessment date, girls were given an inventory to complete that asked which technique: 1) they liked; 2) liked best, 3) wanted the teacher to use; and 4) whether or not they’d use the scale at home. They were also asked to respond to perceptions about their body fat percentage, and whether they believed the scale results to be accurate. Results from the questionnaire indicated that students liked both techniques (SF: Yes=22; No=5; BI : Yes 22; No=5). Students preferred slightly the BI (14=BI; 12=SF; Both=1); preferred the teaher to use the BI (16) over SF (10); and would use the BI at home (25=yes; 2=no). Test retest reliability of BI was .99; while for skinfolds was .97. In summary, the bioimpedance scale seems to be a viable alternative to 2 site skinfold assessment of body composition for junior high school girls in physical education class.
