Abstract

Linear and multidirectional acceleration underpins success in professional soccer match-play. However, the physical qualities that determine these performance indicators are poorly understood in elite players. English Premier League players (n=26) performed isometric mid-thigh pulls (IMTP), bilatera...

However, the physical qualities that determine these performance indicators are poorly understood in elite players. English Premier League players (n=26) performed isometric mid-thigh pulls (IMTP), bilateral and unilateral drop jumps (DJ; from 40 and 20 cm, respectively), bilateral and unilateral countermovement jumps (CMJ) and assessments of linear (5-, 10-, 20-m) and multidirectional (left/right pre-planned and reactive) acceleration.

A 5.4 W&#xB7;kg increase in CMJ predicted a 0.03 s decrease in 5-m sprint time (P=0.02). For 10-m sprint time (1.72&#xB1;0.09 s), 44% of variance was explained by isometric relative peak force (PF; 30.4&#xB1;4.9 N&#xB7;kg) and bilateral relative CMJ PPO (54.5&#xB1;5.3 W&#xB7;kg). A 5.4 W&#xB7;kg increase in CMJ predicted reduced 10-m sprint times by 0.04 s (P=0.01). For 20-m sprint time (2.94&#xB1;0.11 s), 55% of the total variance was explained by isometric relative PF (30.4&#xB1;4.9 N&#xB7;kg) and relative CMJ PPO (54.5&#xB1;5.3 W&#xB7;kg). Increases of 5.4 W&#xB7;kg in bilateral CMJ predicted an improvement of 20-m sprint time by 0.06 s (P=0.002). Contributions were insignificant (P&gt;0.05) for pre-planned and reactive multidirectional acceleration. Relativized indices, especially those related to force production during CMJ and IMTP tests, likely underpin linear but not multidirectional acceleration performance in professional soccer players.
