An objective description of routine sleep habits in elite youth football players from the Middle-East.

Background And Study Objectives: Adequate sleep is essential to support preparation and recovery processes for training and competition in athletes.

This study aimed to provide an objective description of routine sleep habits in elite youth football players from the Middle-East.

Bilateral Deficit and Bilateral Performance: Relationship with Sprinting and Change of Direction in Elite Youth Soccer Players.

The purpose of the study was to examine the differences in bilateral deficit (BLD) at different loadings during the half-squat jump (SJ) and horizontal countermovement jump (HCMJ) to determine if there is a relationship with linear sprint or change of direction (COD). The second goal was to check if fast players were more powerful in SJ and HCMJ than slow players in bilateral performance (BP). Twenty-seven male youth soccer players participated in the study.

Talent identification (TID) and development (TDE) are large fields in professional soccer and in science. However,  TID and TDE processes in youth academies have not been assessed in detail. As such, our aim was to survey professional clubs from around the world about their youth academy TID and TDE processes, with 29 clubs responding to the survey.

No association between perceived exertion and session duration with hamstring injury occurrence in professional football.
