To better understand the relationship between BMI and %BF in an older athletic population, BMI and %BF were measured in masters athletes (N = 35, Nmale = 24, Nfemale = 11), between 45-65 years. Height, weight, waist circumference, BMI, and %BF via hydrostatic densitometry were determined and compared to the general population. Independent samples t-tests were used to compare measures of body size and composition between the general population and masters athletes. Results indicated that masters athletes had a significantly lower BMI and waist circumference compared to the general population. A chi-squared analysis for goodness of fit was used to determine the sensitivity and specificity of BMI and waist circumference. Results indicated that for the cut point of 25 kg.m-2, BMI was 100% sensitive and 64% specific, indicating that the accuracy of BMI is limited in this population. In summary, masters athletes were more often identified as overweight but were not overfat based on %BF, and had significantly lower BMI and waist circumference when compared to the general population.
