### Performance Indicators to Predict Future Success  
The identification of reliable performance markers plays a crucial role in physiology research and applied studies, aiding in training planning and talent selection [6; 7]. While many studies have focused on describing the physiological profiles and training responses of youth and elite cyclists of different disciplines [3; 10; 27; 28; 29], track cycling remains an area with relatively limited investigation [2]. Moreover, exploring easily accessible performance data, such as those available in UCI databases, can provide valuable indicators of track cyclists' performance levels across different seasons [6].  
In light of this, the present study identified a potentially more reliable indicator of future success, defined as the \"corrected UCI points score\". Achievers in track cycling tended to exhibit higher scores in the junior category compared to the riders who did not reiterate their high youth performances, which was notable in the sprint disciplines. Additionally, gender differences were observed, with a more pronounced scoring gap between the achievers and non-achievers in the female cyclists compared to males. However, it is essential to interpret these findings with caution, as the effect size of these differences was found to be relatively small. Therefore, even though the \"corrected UCI points score\" showed promise as a potential performance marker, it should be used judiciously as an indicative tool for future talent assessment. Recent studies have explored the value of publicly available data as a means to predict road cycling performance and identify talent among U-23 category riders [6]. However, uncertainties persist when considering younger athletes in the junior category. Various studies have suggested a trend toward weaker predictive power in the very early categories, but stronger predictability as athletes approach the U-19 and U-23 categories [8; 9; 11]. In the context of talent identification in track cycling junior categories, expert coaches, athletes, and former athletes acknowledge the limitations of relying solely on publicly available UCI indicators, especially considering the increased opportunities for showcasing throughout the season offered by a denser competition calendar. While achieving high UCI scores remains essential for qualification to events like the world championships, specific results obtained in key competitions emerge as richer/more meaningful indicators for talent scouts and national team selectors, attracting sponsors to support the future careers of young athletes at the same time. Moreover, advancementsin laboratory and field-based performance analyses could provide a more comprehensive understanding of an athlete's current physiological status and potential.  
Overall, the present study sheds light on the potential value of the \"corrected UCI points score\" as a performance marker in track cycling. It highlights the significance of incorporating easily accessible UCI data alongside physiological testing as part of a more comprehensive performance analysis approach for talent identification and training planning. The UCI scores and derived indicators could serve as complementary markers, helping establish performance targets to qualify for prestigious events or quantifying the necessary competition experience to reach higher-level competitions. Nevertheless, coaches and athletes stress the need for further research and a cautious interpretation of the results to ensure the responsible use of such performance indicators in talent selection processes.
