Soccer is a multifaceted sport. Performance depends on many factors: technical, biomechanical, tactical, mental and physical.

Aims

The purpose of this study is the analysis, through the use of GPS devices, of the parameter of the external load of anaerobic metabolism in official championship matches. This study considers: time match, players’ roles and round.

Methods

We used GPS devices (GPEXE 18 Hz) to analyze a team of 28 soccer players without goalkeepers (age 18,6 ± 0.629 years; height 1,79±0.062 m; weight 74.4±6,901 kg).
We recorded 22 matches of “Primavera” championship choosing only the players who finished the match.

We analyzed some parameters: Distance, Equivalent Distance Coverage, Anaerobic Energy, Accelerations, Decelerations, Metabolic Power and Recovery times.
The statistical analysis was processed using the multi-factor ANOVA procedure.

Results

There’s no statistically significant difference between the first and second round, but there’s differences between the first and second halfes (P-value<0.05) for Distance, Equivalent Distance Acceleration, Deceleration, Metabolic Power.
We noticed that in second halves there was more rest.

The midfielders covered more distance and had higher values of metabolic power.
The attackers had higher values of accelerations and decelerations.
The defender had a lower physical demands.

Conclusions

Soccer players’ performance decline markedly during the second half, and this study suggest which parameter had a greater decrement for plan an appropriate training program.

The different exercise intensities produced by two SSG formats, allow to organize the training sessions in the weekly microcycle.
