BMI unable to clearly state measure of high school footballers

BMI unable to clearly state measure of high school footballersAccording to a study presented at American College of Sports Medicine's 57th Annual Meeting in Baltimore, high school football players might be defined as obese and overweight when using body mass index measurements.

About 71 males belonging to seven different high schools were examined by a team of researchers. Body weight, height, age-adjusted body mass index (BMI), body fat percent (BF %), fat mass and fat-free mass of the subjects, were measured by the team following an overnight fast. The team did these tests as they would assess the effectiveness of BMI as an analyst of being overweight or obese.

According to BF %, about 45 of the subjects were considered as normal weight, the BMI stated that 26 were normal weight; 18 were declared overweight using BF% as compared to 21 who used BMI and six were called obese by BF% as compared to 24 using BMI.

Gary D. Steffes stated, "The use of age-adjusted BMI percentile rank in high school football players is not effective for determining overweight/obesity levels as it can lead to misclassification of overweight and obese status. This is especially true for bigger athletes such as linemen."
