Physical Performance Differences Between Starter and Non‐Starter Players During Professional Soccer Friendly Matches

a high intensity ( Bradley et al., 2009 ; Di Salvo et al. 2009). A large number of studies have reported on the specific energetic and physical performance demands of elite soccer players, including the effects of positional variation, using time motion analysis ( Bradley et al., 2009 ; Di Salvo et al., 2009 ; Rampinini et al., 2007). For example, central midfielders were reported to cover more total distance than any other positions with the wide midfielders and fullbacks also displaying superior high‐intensity efforts during a match ( Bradley et al., 2009 ; Di
