• Description:
  Over the last 30 years, the obese population has grown to over 60 million people in the US. Along with obesity, the associated risk of injury related to biomechanical factors also increases. In order to understand these mechanisms of obesity-related risk of injury, accurate body segment parameter (BSP) measurements are required to model joint contact forces and muscle forces applied during a given task. Current anthropometry tables, which show the mass of each body part as a percent of total body weight (BW), and center of mass (COM) and radius of gyration (RG) locations as percent of segment length were compiled using healthy, college-age adults, however these parameters have shown to be inaccurate in predicting BSP's in subjects with an increased body mass index (BMI), as well as in different age groups. Several methods exist for determining BSP's including cadaver-based studies, magnetic resonance imaging, computed tomography, and measurements based on bony landmarks, however these methods have some issues as far as cost, time required, and high doses of radiation. Dual energy x-ray absorptiometry (DXA) is a validated method of determining BSP's in vivo that avoids these common problems. DXA scans are commonly used to determine bone density and body composition, as well as mass calculations. The scan itself is an inexpensive, low radiation scan that can differentiate between bone, muscle, and fat. The goal of this study is to determine differences in segment masses, COM's, and RG's in normal weight (NW), overweight (OW), and obese (OB) young males. We will focus on the differences in the torso and dominant-side thigh. [Description provided by NIOSH]
