体能是集体球类项目的核心竞技能力之一，获取运动员需要达到的具体体能标准对于训练目标设定和训练内容规划具有重要意义。研究通过受试者工作特征曲线(receiver operating characteristic curve，ROC)分析过去20年(2004-2023年)美国国家橄榄球联盟(National Football League，NFL)选秀联合测试大会(Scouting Combine，SC)中的体能测试和选秀结果，探究NFL SC选秀成功的体能标准阈值。结果:1)NFL SC中的体能测试能够分辨选秀结果(P＜0。05)，符合体能标准的运动员选秀成功的概率是未达到标准运动员的1。5～4。4倍(OR=1。514～4。413，P＜0。05);2)选秀标准可以区分不同指标对不同位置运动员的影响程度;3)选秀指标在纵向上具有明显变化，该变化在很大程度上反映了橄榄球运动员体能需求的变化及其趋势。研究结果为我国美式橄榄球体能训练中的标准和目标设立提供了科学化研判思路。
The Research of Physical Fitness Criteria for NFL Draft Success from 2004 to 2023
Physical fitness is one of the core competitive abilities in team sports,and it is important to confirm the specific levels that athletes need to achieve in order to set training goals and training plans.In this study,we analyzed the physical fitness test and draft results of the National Football League(NFL)Scouting Combine(SC)over the past 20 years(from 2004 to 2023)through ROC curve,so as to investigate the threshold of physical fitness standard for draft success.Results:1)NFL draft fitness tests could discriminate draft outcomes(P＜0.05),the athletes who meet fitness standards was 1.5 to 4.4 times more likely to be drafted successfully than athletes who do not meet the standards(OR=1.514-4.413,P＜0.05);2)The fitness standards of draft can distinguish the effects of different index on athletes at different positions;3)The longitudinal draft stands was changed significantly,and the changes reflect the trend of physical fitness requirements in rugby players.This study provides new ideas and methods for scientific setting of standards and goals in the physical training of American football in China.
