Comparison of anaerobic power between tactical positions in soccer players: a retrospective study

This study aimed to compare the maximal anaerobic power (Pmax), mean anaerobic power (Pm) and fatigue index (FI) among soccer players of different tactical positions. For this purpose, 248 professional soccer players (25.8+ or -1.72 years old, 77.52+ or -4.90 kg and 178.48+ or -5.63 cm) from the 1 super(st) and 2 super(nd) division of the Rio Grande do Sul State, Brazil, participated in this study. They were evaluated between 1999 and 2010 and divided into five positions: goalkeepers (GK) (n=28), external defenders (ED) (n=35), central defenders (CD) (n=54), midfielders (MF) (n=81), and forwards (F) (n=50). The RAST test was performed to evaluate their Pmax, Pmed, and FI. ANOVA one-way and Tukey's post hoc were used to evaluate the relationship between the variables; significant level was p
