Resumo(s)
O presente estudo comparou a carga semanal de treino interno em 10 microciclos (M) em atletas sub-12. Vinte e oito jogadores de futebol sub-12 (idade, 10,96 ± 0,19 anos, altura, 152,82 ± 7,47 cm, peso 40,76 ± 6,29 kg) participaram no estudo. A carga de treino interno foi quantificada através da perceção subjetiva de esforço da sessão. Foram calculadas a carga semanal média, a carga semanal acumulada, a monotonia e tensão do treino para cada M (1 a 5 do período preparatório e 6 a 10 do período competitivo). Os resultados revelaram diferenças significativas considerando todas as métricas (p < 0,001 para todas). Especificamente, a carga semanal média foi menor nos M4 e M7, enquanto a carga semanal acumulada foi menor nos M1, M2 e M9. A monotonia do treino e o esforço do treino apresentaram os valores mais baixos (p < 0,001 para todos) nos M1 e M9 (0 unidades arbitrárias) e os mais elevados no M6. Os dados revelaram variações de carga com todas as métricas analisadas. No entanto, as principais diferenças foram encontradas entre os microciclos com menor número de sessões de treino (uma ou duas) e os restantes microciclos, o que revela uma manutenção geral da carga ao longo dos períodos preparatório e competitivo. No entanto, este parece ser o primeiro estudo realizado com atletas sub-12, fornecendo dados relevantes para os treinadores e as suas equipas técnicas.
The current study compared weekly internal training load across 10 microcycles (M) in under-12 athletes. Twenty-eight under-12 soccer players (age, 10.96 ± 0.19 years; height, 152.82 ± 7.47 cm; weight, 40.76 ± 6.29 kg) participated in the study. Internal training load was quantified using session Rating of Perceived Exertion. The average weekly load, accumulated weekly load, monotony and training strain were calculated for each M (1 to 5 of the preparatory period and 6 to 10 of the competitive period). Results revealed significant differences considering all metrics (all, p < .001). Specifically, the average weekly load was lower in M4 and M7, while the accumulated weekly load was lower in M1, M2 and M9. Training monotony and training strain showed lower values (all, p < .001) in M1 and M9 (0 arbitrary units) and the highest on M6. The data revealed load variations with all metrics analysed. However, the main differences were found between the microcycles with the lowest number of training sessions (one or two) and the remaining microcycles, which reveals a general maintenance of the load throughout the preparatory and competitive periods. However, this appears to be the first study carried out with under-12 athletes, providing relevant data for coaches and their technical staff
