Abstract

Early specialization in sports for young elite athletes was undertaken for a variety of positive reasons, but it also can lead to increased vulnerability to injury, burnout, limited skill development, and negative effects on mental well-being as a result of intense training from a young age. The purpose of this study was to determine the relationship between age of sport specialization and training components to the achievements. This was a correlational survey and a cross-sectional approach to elite athletes in the city of Bandung. The sample for this study consisted of 84 high-level athletes who competed in 27 different sports and were eligible for athlete incentives from the government. Athletes were surveyed using a questionnaire to answer questions about their debut age, training frequency, duration, intensity, and highest championship achievement. The results of bivariate analysis showed that age, gender, age of specialization, duration of exercise, and intensity of exercise were not related to sports achievement. Based on the results of statistical analysis, it was known that the frequency of exercise was significantly correlated with sports achievement. Compared to athletes who train less than five times per week, athletes who train more than five times per week were found to have higher performance. Future possible research will assist in identifying the success factors of young athletes who begin sports specialisation at a young age.

Abstract

The development of measurement instruments for basketball skills and physical performance is essential to support athlete training programs based on systematic and data-driven approaches. Although basketball in Indonesia has grown steadily, the transition from amateur to professional levels still faces challenges, one of which is the absence of standardized measurement tools that are both valid and reliable across different stages of athlete development. This study aimed to develop and examine the validity and reliability of basketball skill and physical test instruments intended for athletes aged 12–18 years. A quantitative methodological approach was employed, focusing on content validation through expert judgment. The validation process involved ten experts in basketball and sport science who assessed the relevance of each test item. Content validity was analyzed using the Content Validity Ratio (CVR), while inter-rater reliability was examined with Fleiss’ Kappa. The results indicated that of the 11 skill test items, 7 were valid and reliable, with coefficients ranging from moderate to almost perfect. However, several items, such as passing version II, right- and left-hand dribbling, and speed dribbling shoot, were deemed invalid and showed low reliability (slight). In the physical test domain, 8 of 10 items were validated and demonstrated almost perfect reliability, while the standing long jump and hexagon test were found invalid and yielded low reliability (poor). These findings suggest that the developed instruments meet validity and reliability standards for most items, and thus hold potential as reference tools for assessing physical and technical performance in youth basketball. Furthermore, the instruments provide a foundation for future studies involving field trials to confirm their effectiveness in athlete development programs.
