Abstract

Purpose: The powerful activity profile of elite soccer match play has not been 4 documented appropriately to inform specific maximal power assessment and 5 development criteria. The aims of the current study were to develop a soccer specific 6 powerful action (SSPA) notational analysis coding system that could be used to 7 compare frequency and durations of powerful actions during elite youth soccer match 8 play. Methods: Sixteen elite male English Premier League (EPL) Academy players 9 (19±1 yrs) were recorded by an individual camera during sixteen competitive EPL U18 10 and U21 games. Video footage was analyzed using performance analysis software and 11 SSPAs were coded according to the following categories: initial acceleration, leading 12 acceleration, sprint, unilateral jump and bilateral jump. Results: The SSPA coding 13 system demonstrated very good inter- and intra-rater objectivity (kappa coefficients 14 ≥0.827). Elite youth EPL soccer players undertook significantly more initial (31±9) and 15 leading (37±12) accelerations than sprints (8±3; p=0.014, d=1.7, and p<0.001, d=1.7, 16 respectively) and jumps (6±5; p=0.002, d=1.7 and p<0.001, d=1.7, respectively). 17 Players performed a significantly greater number of initial and leading accelerations 18 with action durations below 1.5s compared to above 1.5s (p=0.001, d=1.6, and p=0.002, 19 d=1.4), respectively. Conclusions: Our SSPA coding system provides an objective 20 observational instrument for quantifying the frequency and duration of powerful 21 actions performed during elite soccer match play. In our sample of elite youth soccer 22 players, horizontal accelerations of short duration (<1.5s) from different starting speeds 23 appear the most dominant powerful action in elite youth soccer match play
