Abstract | The aims of this study were to analyze the effect of contextual variables on physical metrics during transitions and investigate repeated transitional activities during transitions. Data was collected from 10 matches (23 elite soccer players). A total of 4249 individual observations were recorded including 1164 positive transitions (defense-to-attack), 1269 negative transitions (attack-to-defense), 1120 fast attacks, and 696 high pressure activities. Metrics per minute (m·min-1) as well as absolute variables: Total Distance (TD), high-speed running distance (HSRD, >19.8km·h-1), sprint distance (SD, >25.2km·h-1), relative high-speed running distance (VelB4), relative sprint distance (VelB5), acceleration distance (AccB3 Dist., distance with variations in running speed >3m·s-2), the number of high-intensity accelerations (HI Acc, >3m·s-2) and decelerations (HI Dec, >3m·s-2) were quantified. Significant effects of match half were found for TD (p <.001; ES =.03), HSRD (p = .023; ES = .012), VelB4 (p < .001; ES = .04), and HI Dec (p = .037; ES = .010). Match outcome had a relation to TD (m), HSRD (m) (p < .001), SD (m) and VelB4 (m) (p = .011) as well as VelB5 (m), and AccB3 Dist. distance (m) (p = .002 and p = .020, respectively). Performance in lost matches was lower in the 2nd half (p≤0.05). This study indicates that players are exposed to repeated short and intermittent high velocity actions together, highlighting the need to move away from 90min averages and pay more attention to transitional activities in modern training design. |
