Field dependence-independence (FDI) as measured by Rod-and-Frame Test (RFT) is related to sports ability and potential since RFT involves the use of body information (Brady, 1995). Recently, research also indicates the close relationship between FDI and physical activity (PA) involvement (Liu, 2003, 2004). Meanwhile, it becomes aware that black adolescents’ daily PA level is lower than their white peers (CDC, 1996). The factors contributing to black adolescents’ lower PA level, however, are not totally clear. The purpose of the study was to examine if FDI as measured by RFT was related to the difference of PA level between black and white adolescents. The Self-Administered Physical Activity Checklist (Sallis et al., 1996) was administered to 113 American middle school students (47 black, 27 girls, 20 boys; 66 white, 37 girls, 29 boys) to determine their PA level. Potable RFT (Oltman, 1968), most frequently used when involving FDI and sport potential (Brady, 1995), was employed to examine the participants’ FDI status. The results of two-way (gender × race) MANOVA showed a significant difference (F_{(1, 109)} = 9.44, p < .01) in FDI status indicating that black adolescents were significantly more field dependent than white adolescents, suggesting the lower sport potential on the part of black adolescents. Consistent with the difference in FDI, the two-way MANOVA also yielded significant differences in four of six PA variables in favor of white adolescents: (a) minutes of PA (M: 116.48 for white vs. 77.62 for black, F_{(1, 109)} = 5.97, p < .05), (b) MET score (10.37 vs. 6.60, F_(1,109) = 5.76, p < .05), (c) weighted MET score (11.13 vs. 7.02, F_(1,109) = 6.03, p < .05), and (d) weighted moderate and vigorous PA MET score (8.88 vs. 5.76, F_(1,109) = 3.97, p < .05). FDI as measured by RFT reflects the effectiveness of using body information, or kinesthetic feedback, which is one factor related to sport potential and PA involvement as well. The results suggest a possible relationship between black and white adolescents’ difference in FDI status and their disparity in PA involvement. Enhancing black adolescents’ sport potential is desirable since it may contribute to the enhancement of black adolescents’ PA level.
