[quote=Anonymous][quote=Anonymous]Really quick. Some of you are conflating Relative Age Effect (the selection of talent by relation to the beginning cutoff date for youth sports grouping) with biological maturity ( the maturation rate at which an individual reach full adult performance).

The biological maturation rate (age) directly affects not only physical attributes (height, force, oxygen), but psychological and emotional maturation. There are tests both hormonal and structural that help determine biological age. RAE is generally determined by the specific organizational structure around that sport, which does change based on culture/country.

Most studies find that during talent selection, there is a bias toward Q1 selection at the pre-puberty growth stage. This also relates to the biological maturation of the person. Since this skews selection, there have been efforts to combat the bias selection and allow players of talent but less biologically mature to play with players closer to their biological maturation.

Weather MLS next is applying it correctly, the goal I assume still attempts to account for the different maturation rates related to selection and performance.

On the other side, there has also been studies that show surviving RAE may provide even greater indication of skill/aptitude which means Q2, Q3, and Q4 selections if still engaged in the sport often can outperform early selections after adult maturation.

There is a lot to read on the subject if you want.

This is an important distinction.  Thanks for laying it out.  The early selection of young kids for top teams (e.g. U11) allows those kids access to better training resources and coaching.  And at those early pre-pubescent the biological age matters most to physical stature and maturity.  Once the kids start hitting puberty, that is the more important factor in size and weight.
