    ENGLISH ABSTRACT : To ensure success for athletes at the highest level, it is of outmost importance to develop them to the best of their abilities. There is a wide range of laboratory and field-based tests to identify talent and help develop these biomotor abilities. The long term athlete development models can help coaches to develop children to the best of their sporting abilities at the correct tempo. A total of 550 children, 275 boys and 275 girls, took part voluntarily in the study. The study design was an observational study design. The different biomotor abilities of speed, power and strength were investigated with field-based testing equipment in children. The two primary findings in the current study were the correlation between SLJ and sprinting performance in children and also the correct phase when children should train the various biomotor abilities. The boys had significantly performed better than the girls in speed (p=0.01-0.05), SLJ (p=0.01-0.05) and handgrip strength (p=0.01-0.05). The results indicated a strong correlation (r=0.61-0.85) between SLJ (measuring power) and sprinting speeds at 2.5 m, 5 m, 10 m and 20 m for boys and girls. Furthermore, the results correspond well with the YPD model that proposes that a child’s speed, power and strength can be trained and developed over an extended period throughout childhood. Initially the LTAD model were the front runner the theory that children should systematically be trained throughout childhood, but according to this model there were only specific windows of opportunities at certain ages to train certain biomotor abilities.According to results found in this study the newer athlete development models, the models after the LTAD model, is more inline and this approach should be used in future to develop children to the best of their abilities to succeed in sport at the highest level. Coaches can use reliable field-based tests like SLJ to develop talent and discover new talent
