The purpose of this study was to present a profile of body size and composition of National Football League (NFL) players prior to the start of the regular season. Fifty-three members of the Indianapolis Colts professional football team were measured for height, body mass, and percentage body fat using the BOD POD air-displacement plethysmography system during summer camp of the 2003 football season. These data were categorized by position for comparison with previous studies of NFL football players. The relationships observed were as follows (= represents nonsignificant; > represents p < or = 0.05): Height: Offensive Line = Defensive Line = Quarterbacks/Kickers/Punters = Tight Ends > Linebackers > Running Backs = Wide Receivers = Defensive Backs. Body Mass: Offensive Line = Defensive Line > Tight Ends = Linebackers > Running Backs = Quarterbacks/ Kickers/Punters > Wide Receivers = Defensive Backs. Percentage Body Fat: Offensive Line > Defensive Line > Quarterbacks/ Kickers/Punters = Linebackers = Tight Ends > Running Backs = Wide Receivers = Defensive Backs. Comparisons to teams in the 1970s indicate that body mass has increased only for offensive and defensive linemen; however, height and body fat among player positions have not dramatically changed. Furthermore, the body mass index is not an accurate measure or representation of body fat or obesity in NFL players. These data provide a basic template for size profiles and differences among various positions and allow comparisons with other studies for changes in the NFL over the past 3 decades.
本研究的目的是呈现国家橄榄球联盟（NFL）球员在常规赛开始前的身体尺寸和组成概况。在2003年橄榄球赛季的夏令营期间，使用BOD POD空气置换体积描记系统对印第安纳波利斯小马队职业橄榄球队的53名成员进行了身高、体重和体脂百分比测量。这些数据按位置分类，以便与之前关于NFL橄榄球运动员的研究进行比较。观察到的关系如下（=表示无显著差异；>表示p≤0.05）：身高：进攻线球员 = 防守线球员 = 四分卫/踢球手/弃踢手 = 近端锋 > 线卫 > 跑卫 = 外接手 = 角卫。体重：进攻线球员 = 防守线球员 > 近端锋 = 线卫 > 跑卫 = 四分卫/踢球手/弃踢手 > 外接手 = 角卫。体脂百分比：进攻线球员 > 防守线球员 > 四分卫/踢球手/弃踢手 = 线卫 = 近端锋 > 跑卫 = 外接手 = 角卫。与20世纪70年代的球队相比，表明只有进攻线和防守线球员的体重有所增加；然而，球员各位置的身高和体脂并没有显著变化。此外，身体质量指数并不是衡量NFL球员体脂或肥胖程度的准确指标。这些数据为不同位置的身体尺寸概况和差异提供了一个基本模板，并允许与过去30年NFL的其他研究进行比较。
