Werkself complete performance tests

In addition to the internal and orthopaedic tests, that were carried out in part on Monday, 17 players (split into groups of three) and excluding the international players, completed a range of tests on strength, coordination, movement, balance, acceleration and stamina. "With the help of the data, we produce an individual profile for each player to see exactly where the particular strengths, weaknesses or performance limiting factors are," explained Malte Krüger, the head sports scientist at Bayer 04. The data acquired primarily serves to optimise the training programme over the course of the pre-season. "That means the players can work in a targeted and individual way with our fitness coaches Schahriar Bigdeli, Terry Peters and Daniel Jouvin to endeavour to make up deficits or to reduce the risk of injury – without the daily training on the pitch having to suffer," added Krüger.

Of course, the aim is to be as well prepared as possible for the three competitions facing the Werkself of the Bundesliga, the Champions League and the DFB Cup. "We want to keep all players fit and healthy through the season and make sure they are fully fit when the busy weeks start," said Krüger.

Kai Havertz, Lukas Hradecky, Aleksandar Dragovic, Tin Jedvaj and Paulinho, who were given extra leave due to their international appearances at the beginning of June, will complete the performance tests on Sunday.
