Preseason measures were taken 1–2 weeks before the start of fall practice. Postseason measures were taken within 1 week after the last game of the season and spring season testing was done approximately 145 days after postseason testing. Anthropometric measures were made in light clothing with shoes removed. Height was measured in duplicate using a portable stadiometer (National Football League [NFL] Model 225, Hanover, MD, USA) and reported to the nearest 0.5 cm. A third measure was taken if the duplicate measures differed by more than 0.5 cm. Weight was measured to the nearest 0.1 kg using a digital scale (SECA, Model 770).
