NFL Draft Trainee Performance Profiling by Position
Abstract
The purpose of this study was to profile NFL draft trainees on physical and performance characteristics. Fifty-four players were categorized into Big, Big-skill, and Skill groups. We measured body fat (BF%), lean body mass (LBM), total mass, sprinting forces and ground contact time (GCT), jump height (JH), jump absolute (AJP), and relative (RJP) power, and reactive strength (RS). ANOVA determined between-group differences. Profiles were viewed via Z-score radar plots. There was a significant between-group difference in characteristics, F(24, 76)=5.18, p<0.001;Wilk's Λ=, partial η2=0.621. Post-hocs showed Skill had greater JH (p<0.001), RJP (p<0.001), and RSI (p=0.005) versus Big. Big had greater values versus Skill and Big-Skill in BF% (p<0.001), total mass (p<0.001), LBM, (p<0.001), AJP (p<0.001). GCT was longer in Big versus Skill (p<0.001) and versus Big-skill (p=0.007). Sprinting force was not different, p>0.025. Body composition and jump performance differences are pronounced between Skill and Big. Big-skill possess characteristics from both groups.
