  The main objective of coaches is to provide a structured training program, ensuring a balance between the application of training loads and periods of recovery aiming to increase physical fitness. Considering this, the present study aimed to investigate the associations between internal training load indexes and changes in performance in young football players during a 4-week pre-season. 17 male athletes participated in the study, nine belonging to Under 15 category and eight belonging to Under 17 category, being the performance analyzed through the Yo-yo Intermittent recovery test level 1. During the pre-season the rating of perceived exertion (RPE) of the session were monitored to determine the internal training load (ITL), weekly training load (WTL), monotony and strain. Increases in WTL, monotony and strain were identified for both categories by comparing the values obtained in the first two weeks of training with the last two weeks preceding the competition. A significant increase in the distance covered in the Yo-Yo IR1 test was identified in both categories. During the pre-season a negative and significant correlations were found between the ITL indexes and the performance in the Yo-Yo IR1 for both categories. However, no relationship was found between WTL and performance for the U-15 category. Evidences found in the present study show that young athletes with higher ITL parameters during the preseason are more susceptible to lower performance gains.

  O principal objetivo de técnicos é fornecer um programa de treinamento estruturado, levando em consideração um balanço entre a aplicação de cargas de treinamento e por períodos de recuperação visando o aumento do desempenho físico. Visto isso, o presente estudo objetivou investigar as associações entre os índices de carga interna de treinamento com as mudanças no desempenho em jovens atletas de futebol durante uma pré-temporada de 4 semanas. Participaram do estudo 17 atletas do sexo masculino, nove pertencentes a categoria Sub-15 e oito pertencentes a categoria Sub-17, sendo o desempenho avaliado por meio do teste Yo-Yo Intermittent Recovey test nível 1. Durante a pré-temporada foram avaliados a percepção subjetiva de esforço da sessão (PSEsessão) para determinação da carga interna de treinamento (CIT), carga de treinamento total semanal (CTST), monotonia e esforço global de treinamento. Foram identificados aumentos na CTST, monotonia e esforço global de treinamento para ambas as categorias comparando os valores obtidos nas duas primeiras semanas de treinamento com as duas últimas que precediam a competição. Foi identificado um aumento significativo na distância percorrida no teste de Yo-Yo em ambas as categorias. Durante a pré-temporada foram encontradas correlações negativas e significantes entre os parâmetros de CIT e o desempenho no teste de Yo-Yo para ambas as categorias. Entretanto, não foram encontradas relações entre a CTST e o desempenho para a categoria Sub-15. Desta maneira as evidências encontradas demostram que jovens atletas que apresentam parâmetros de CIT elevados durante a pré-temporada estão mais suscetíveis a apresentarem menores ganhos de desempenho. ABSTRACT Association between parameters of internal training load and physical performance in pre-season football athletesThe main objective of coaches is to provide a structured training program, ensuring a balance between the application of training loads and periods of recovery aiming to increase physical fitness.
