Internal load of youth elite soccer players in various small-sided games

Summary/Abstract: The main aim of the study was to find more information about the internal load of elite young soccer players in small-sided games with different parameters. The group consisted of elite soccer players (n = 16) in under 15 years category. The team participated in the 1st Slovak league. We've tracked the time spent by players in selected bioenergetics load zones (% of maximum HR) during small-sided games with 2:2, 3:3 players and 25x18-meter and 30x25-meter playing field. We used the basic mathematical-statistical characteristics and Wilcoxon t-test for non-parametric selections. We found that in the category under 15 years, a larger number of players (3: 3) in the small-sided games indicates less time spent in bio-energy zones 4. and 5. Indirect intentions also apply to the dimensions of the playing field, depending on the time spent in load zones no. 4. and 5. That means that the larger the size of the playing field causes less time spent by players in bio-energy load zones that are imported to us. If we want to use them as a comprehensive training tool (game training), this is what we consider to be an adequate training tool.
