SUMMARY:

INTRODUCTION: Young athletes of the same chronological age may vary in biological maturation among their peers, which can generate competitive inequality. Biobanding is an attempt to minimize these differences by grouping athletes based on maturational rather than traditional age groups (cronological age - CA). OBJECTIVE: To compare the external (ETL) and internal (ITL) training load and thecnical performance in small-sided games (SSG) in athletes grouped in biological bands and in athletes grouped in chronological ages (CA) METHODS: 20 young male soccer athletes (age: 11.8 ± 1.15 years; body mass: 51.36 ± 18.14 kg; height: 153.64 ± 10.57 m; sitting height: 78.37 ± 5.88 cm; vertical jump: 25.03 ± 5.43 cm; aPHV: -1.47 ± 1.18) were evaluated in 6 training sessions carried out in 3 consecutive weeks with teams formed based on chronological age and somatic maturation level (biobanding). ETL (PlayerLoad) and ITL (session PSE and TRIMP) were monitored during all training sessions. The athletes' technical performance was analyzed through video recordings of all games in all sessions. The teams played the SSG in 5x5 format on the field with measures of 40m x 25m and the games had 4 halves of 5 minutes and 3 minutes of active recovery between halves. The biobanding groups were divided into two conditions according to the years from Peak Hight Velocity (PHV) classification: condition 1 (pre-PHV) -2 years from PHV (-2.5 to -1.5) and condition 2 (PHV) -1 year from PHV (-1.5 to -0.5). The paired t test was used to analyze the same variables (CET, CIT and technical performance) between the pre-PHV and PHV conditions and the CA condition. RESULTS: The pre-PHV group had significantly higher TRIMP (99.42 ± 2.71 au) compared to the IC group (91.08 ± 4.05 a. u.). The PHV group produced significantly lower external load (11.96 ± 0.48 a. u.) compared to the CA group (12.66 ± 0.43 a. u.). In realtion to thecnical performamnce, the pre-PHV group produced significantly more tackles compared to CA group. There was no significant difference in the parameters of total involvement between the analyzed groups. CONCLUSION: Under-13 athletes when grouped by somatic maturation (pre-PHV) produced significantly higher TRIMP value and significantly more tackles compared to CA group and athletes from PHV condition produce significantly lower external load compared to CA group. Regarding total involvement, there were significant differences to state that a change in the way of classifying the groups, when there are no large maturational amplitudes, is necessary.
