Figure 1. Average 20-meter sprint speed and V̇O_2max, normalized to lean body mass, for each playing position. Each data point represents individually obtained values of male young elite soccer players. A) Means and standard deviations for average sprint speed are presented for forwards (n = 9), attacking midfielders (n = 8), defending midfielders (n = 4), central defenders (n = 4), and full-backs (n = 4). B) Means and standard deviations of normalized V̇O_2max are displayed for forwards (n = 9), attacking midfielders (n = 8), defending midfielders (n = 5), central defenders (n = 4), and full-backs (n = 4). There were no significant differences between the playing groups for average sprint speed (P = 0.769) and normalized V̇O_2max (P = 0.241).
