The time required to perform the three-site and seven-site measurements were also recorded. The Jackson Pollock three-site (thigh, suprailiac, triceps) and seven-site (thigh, suprailiac, triceps, abdominal, subscapular, chest, and axilla) equations were used to determine body fat percentage values. Study participants included 40 National Collegiate Athletic Association (NCAA) Division-II female athletes from volleyball, soccer, and softball teams. It was hypothesized that body fat percentage determined via the seven-site method would be different from those obtained by three-site measurement technique. Thus, the purpose of this study was to compare the three-site and seven-site methods using the BodyMetrix™ to determine body fat percentage in female collegiate athletes. However, the three-site technique allows for faster testing and a reduction of time needed to test an entire team or multiple sports teams. Despite these advantages, research regarding the BodyMetrix™ is limited and has primarily focused on the seven-site testing technique.
Furthermore, the portability and short duration testing features of the BodyMetrix™, allows for testing of a large group of athletes inside or outside of a clinical setting. A-mode ultrasound, when used with the BodyMetrix™, has been found to be a reliable and a cost-effective tool for measuring overall body fat percentage. One method to measure body composition that is gaining popularity is the BodyMetrix™, which uses A-mode ultrasound.
