The present study investigated the effect of training load distribution on the perceived sources and symptoms of stress during 6 weeks of sports training in young athletes. The session RPE method and the DALDA questionnaire were used to assess internal training load and stress tolerance. Twenty young men athletes participated in this study. Repeated measures ANOVA revealed higher training loads in the first and second weeks of training (p<0.05). Interestingly, increased symptoms of stress were also observed in the first two weeks of training, with a similar tendency for sources of stress when the group was analyzed as a whole. A significant increase in the "worse than normal" answers in part B of the DALDA questionnaire (symptoms of stress) was observed for the subgroup submitted to a higher training load (>400 AU) (two-way ANOVA, p<0.05). The present findings support the hypothesis that the internal training load (session RPE) affects stress tolerance. These results emphasize the importance of regular training monitoring in order to reduce the occurrence of deleterious adaptations and to optimize desired adaptive responses.
