The purpose of this study was to compare normative data from present Division I National Collegiate Athletic Association football teams to those from 1987. Players were divided into 8 positions for comparisons: quarterbacks (QB), running backs (RB), receivers (WR), tight ends (TE), offensive linemen (OL), defensive linemen (DL), linebackers (LB), and defensive backs (DB). Comparisons included height, body mass, bench press and squat strength, vertical jump, vertical jump power, 40-yd-dash speed, and body composition. Independent t-tests were used to analyze the data with level of significance set at p < 0.01. Significant differences (p < 0.01) were found in 50 of 88 comparisons. From 1987 until 2000, Division I college football players in general have become bigger, stronger, faster, and more powerful. Further research is warranted to investigate if these trends will continue.
本研究的目的是比较当前美国大学体育协会（NCAA）一级联赛橄榄球队的标准数据与1987年的数据。球员被分为8个位置进行比较：四分卫（QB）、跑卫（RB）、外接手（WR）、近端锋（TE）、进攻锋线球员（OL）、防守锋线球员（DL）、线卫（LB）和防守后卫（DB）。比较内容包括身高、体重、卧推和深蹲力量、垂直纵跳、垂直纵跳功率、40码冲刺速度和身体成分。使用独立样本t检验分析数据，显著性水平设定为p < 0.01。在88项比较中有50项发现了显著差异（p < 0.01）。从1987年到2000年，一级联赛大学橄榄球运动员总体上变得更高大、更强壮、更快且更有力量。有必要进行进一步研究以调查这些趋势是否会持续。
