The explanation as to why football players are getting older is likely related to a combination of multiple factors. Technology, diet, training, injury prevention, money invested and the expertise of nowadays coaching staffs could all be contributing factors. Teams now train better; players take more care of themselves and science has helped to better understand what is needed to make fewer mistakes. It is also possible that we are expanding the limits of performance.
The practical application of these findings suggest that:
1.We should not just focus on signing very young players. The market value of players decreases drastically after the age of 30, however it appears that at this age athletes can still offer quality performance for a number of seasons. Furthermore, an experienced player may possibly require less time to adapt to a new club and play their best from the moment they join the club.
2. The trend of ageing players appears likely to continue in upcoming years. Players are getting older, especially goalkeepers and centre-backs.
3. The investment made by clubs in research, technology and well-qualified coaching staff may all have contributed to maintaining the value of the players.
