Subjective Indicators of Overtraining and Their Relationship to Sport Fitness: A 1-year Observation of Elite Athletes.

This study explores the relationships among indicators of overtraining in adolescent athletes. The research employed widelyaccepted tools for subjective overtraining indicator detection, as identified through a systematic review. Two groups of athletes were observed, comprising 13 athletes with bi-weekly assessments and 66 athletes with assessments every 3 months over a one-year period. The study analyzed relationships between variables using repeated measures correlations. A correlation matrix was subjected to principal component analysis. Three fundamental groups of indicators, reflecting negative emotionality (accompanied by sleep problems), self-concept characteristics, and core symptoms of overtraining syndrome captured through subjective sport fitness and vigor. This research emphasizes the intrinsic link between emotional and physical aspects in the lives of elite athletes, shedding light on the complex interplay of overtraining indicators in the context of adolescent developmental period.
