To succeed as youth athlete: Is it the dead end in track and field?

It is reasonable to believe that a young athlete who succeeds in a World Youth Championship, will also be successful as a senior athlete. To determine the percentage of success of all World Youth Championship finalists who also became finalists in a subsequent senior World Championship, considering all athletes and events at World Athletics Championships. This study analyzed the eight male and eight female finalists of all the events conducted at the World Athletics World Youth Championship from 1999 to 2009, who also became finalists at the World Athletics World Championship from 2001 to 2011. Percentage of success was calculated for track and field events, for male, female, and both. For all the events, from 1759 finalists in a World Youth Championship only 83, representing 4.72%, were also finalists in a World Championship in 2001, 2003, 2005, 2007, 2009, or 2011. Of those 83 athletes, 45 were males and 38 were female. A low rate of success was found. These results were discussed including injuries, early specialization, biological maturation, and/or overtraining, as possible factors related to this low rate of success
