In 2010, Roger Federer said that the biggest change in the last five year on the men´s circuit was the athleticism of the players.
The physical trainer is an important part of the team and responsible for the implementation of the fitness training programme. This means that in order to increase the chances of playing at a higher level, the physical trainer must work on areas such as coordination, strength, speed, power and resistance. Although there is never a guarantee, a sound foundation in these areas is instrumental in the development and performance of a player.
