Resumo: | The functional asymmetry of the lower limbs has been considered an important factor in the performance of soccer players. In this sense, the purpose of this study was to examine the effects of specific technical training for non-preferred foot on its utilization rate during the game; and to investigate if interruption of a technical training programme for the non-preferred foot influences its utilization rate during the game. Fifty young soccer players were randomly divided into two groups: G1 (n=26, 9.50±1.04 years) and G2 (n=24, 9.58±1.02 years). At the beginning of the first 4 months, each player’s use of both feet during the game was assessed. The study lasted eight months divided into two periods of four months. In the first training period G1 was subjected to a technical training programme directed to the non-preferred foot, while G2 had no constraints on the use of both feet. At the end of the 4th month the two groups were newly assessed. During the second training period G1 and G2 reversed the training programmes. After the 8 months of training the evaluation of the utilization rate of both feet during small-side games was again performed. The main conclusions of the study were: (i) the technical training of the non-preferred foot allowed significant increases in its utilization rate during small-sided games; (ii) the interruption of such training partially reversed this effect. Thus, technical training for the non-preferred foot should be systematically performed in order to maintain the positive effects induced over functional asymmetry. |

Effects of technical training in functional asymmetry of lower limbs in young soccer playersEfeitos do treino técnico na assimetria funcional dos membros inferiores de jovens futebolistasThe functional asymmetry of the lower limbs has been considered an important factor in the performance of soccer players. In this sense, the purpose of this study was to examine the effects of specific technical training for non-preferred foot on its utilization rate during the game; and to investigate if interruption of a technical training programme for the non-preferred foot influences its utilization rate during the game. Fifty young soccer players were randomly divided into two groups: G1 (n=26, 9.50±1.04 years) and G2 (n=24, 9.58±1.02 years). At the beginning of the first 4 months, each player’s use of both feet during the game was assessed. The study lasted eight months divided into two periods of four months. In the first training period G1 was subjected to a technical training programme directed to the non-preferred foot, while G2 had no constraints on the use of both feet. At the end of the 4th month the two groups were newly assessed. During the second training period G1 and G2 reversed the training programmes. After the 8 months of training the evaluation of the utilization rate of both feet during small-side games was again performed. The main conclusions of the study were: (i) the technical training of the non-preferred foot allowed significant increases in its utilization rate during small-sided games; (ii) the interruption of such training partially reversed this effect. Thus, technical training for the non-preferred foot should be systematically performed in order to maintain the positive effects induced over functional asymmetry. A assimetria funcional dos membros inferiores é considerada um fator relevante para o desempenho dos futebolistas. O presente estudo teve como propósitos: verificar se um programa de treinamento técnico para o pé não-preferido promovia o aumento do seu índice de utilização durante o jogo; e indagar se a interrupção do programa de treinamento técnico seria acompanhada pela inversão desse efeito. Cinquenta jovens futebolistas foram divididos aleatoriamente em dois grupos: G1 (n=26; 9,50±1,04 anos) e G2 (n=24; 9,58±1,02 anos). Antes do início do programa de treinamento avaliou-se em jogos reduzidos o índice de utilização de ambos os pés de cada jogador. O programa de treinamento teve a duração de 8 meses, divididos em dois períodos de 4 meses. Durante o primeiro período submeteu-se o G1 a um protocolo de treinamento do pé não preferido, enquanto que o G2 serviu de grupo controlo. Durante o segundo período de 4 meses o G1 interrompeu o treinamento técnico enquanto o G2 passou a realizar treinamento técnico. Terminados os 8 meses do programa de treinamento os dois grupos foram sujeitos a nova avaliação do índice de utilização dos membros inferiores. Concluiu-se que (i) o treinamento técnico direcionado para o pé não preferido permitiu aumentar significativamente o respetivo índice de utilização durante jogos reduzidos e que (ii) a interrupção do treinamento revertia de forma parcial este efeito. Deste modo, o treinamento técnico do pé não preferido de jovens futebolistas deverá ser sistemático de forma a que os efeitos positivos sobre a assimetria funcional possam ser mantidos.Universidade Federal de Santa Catarina.
