| The purpose of this study was to evaluate the physical demands
of English Football Association (FA) Premier League soccer of three
different positional classifications (defender, midfielder and striker).
Computerised time-motion video-analysis using the Bloomfield Movement
Classification was undertaken on the purposeful movement (PM) performed
by 55 players. Recognition of PM had a good inter-tester reliability
strength of agreement (κ= 0.7277). Players spent 40.6 ± 10.0%
of the match performing PM. Position had a significant influence on
%PM time spent sprinting, running, shuffling, skipping and standing
still (p < 0.05). However, position had no significant influence
on the %PM time spent performing movement at low, medium, high or
very high intensities (p > 0.05). Players spent 48.7 ± 9.2% of
PM time moving in a directly forward direction, 20.6 ± 6.8% not moving
in any direction and the remainder of PM time moving backward, lateral,
diagonal and arced directions. The players performed the equivalent
of 726 ± 203 turns during the match; 609 ± 193 of these being of 0°
to 90° to the left or right. Players were involved in the equivalent
of 111 ± 77 on the ball movement activities per match with no significant
differences between the positions for total involvement in on the
ball activity (p > 0.05). This study has provided an indication
of the different physical demands of different playing positions in
FA Premier League match-play through assessment of movements performed
by players.
