Abstract
The objectives were: 1) compare the external load before and after a goal with average match demands, and 2) analyze differences in response of players pre and post goal scored and conceded. 23 official matches of twenty-two youth professional soccer players (age = 20.6 +/- 1.8 years, weight = 73.0 +/- 7.1 kg, and height = 1.80 +/- 7.4 m) were monitored. With Global Positioning System (GPS) were obtained the Distance Covered (DC), DC >21 kmh(-1), DC >24 kmh(-1), Player Load, accelerations and decelerations (+/- 2-3 ms(-2) and +/- 3 ms(-2)) during the mean of the matches (Team) and in the 5 and 10 min before (Pre5 and Pre10) and after (Post5 and Post10) the goals scored and conceded. DC >24 kmh(-1) was higher to the Team in all periods independently of the goal status (p <= 0.05). Similarly, Team showed lower DC >21 kmh(-1) than Pre5 in goals scored and Post5 in goals conceded (p <= 0.05). DC, Player Load (except, Pre10), as well as much of the accelerations and decelerations periods were reduced when the goal was conceded (p <= 0.05). Similarly, accelerations and decelerations were reduced in Post5 when the goal was scored, including accelerations between 2-3 ms(-2) in Post10 and higher than 3 ms(-2) in Pre5 (p <= 0.05). Comparing the same period of scoring or conceding a goal, small differences were observed with higher values during goals scored (p <= 0.05). Around goal moments, players' external load change compared to the match average, varying depending on whether the goal is scored or conceded, and the period analyzed.
