A closer analysis of individual data shows a general trend. It seems that the abdominal skin fold method overestimates BF when compared to the seven point method. The abdominal circumference method, on the other hand, underestimates BF when the subject is above average BF according to the seven site method. This "cut off" seemed to be somewhere within 15.59 % BF and 22.68 % BF. When BF was 15.59 % and lower, according to the seven site method, the abdominal circumference method overestimated BF. It can be seen how a greater than normal musculature of the midsection could falsely decrease the LBW calculation, therefore increasing the % BF calculation. The overestimation of BF on some calculations and an underestimation of BF on others is most likely responsible for the seemingly high correlation with the seven point method shown above. Despite the ambiguity of the abdominal circumference method, it was thought to be more reliable than the seven site skinfold with those individuals above 22.68 % BF. It is known that more obese individuals pose a greater threat to the reliability of skinfold measurements. (Lohman and Roche)
It became evident only after the first few calculations that the trial formulas were not applicable to the population tested in this study. As mentioned before, Behnke and Wilmore's formula's were derived from average age college students. The subjects used in this study were, probably at best, average age college students with excessive muscle mass.
