Abstract
Introduction
In top-level football clubs players and employees are shifting between clubs. Standardised longterm information about each player is difficult to get, especially in performance diagnostics and medical. This abstract presents the idea of developing a test battery for professional football clubs that focuses the combination of performance analysis and medical data. The main issue is to develop a model for healthy reference patterns (HRP) that makes it possible to analyse the health status of each player at one specific point to determine the medical status.
Methods
The chief objective of the development is that the HRP model should meet the needs of the
medical department. Interviews with the employees had been done, leading to four tests: 3D
motion capturing for gait analysis with EMG, maximum strength, drop jump and anthropometrical data. A U17 team (n = 17) of a German Bundesliga Club had passed through the tests. At IsoMed they had done static knee extension and knee flexion of each leg three time. For the gait analysis a treadmill and a Vicon 3D motion capturing system with ”Plug-in Gait” model for the lower body (16 marker) have been used. The test persons had to act in two speed levels (8 km/h = walking / 12 km/h = running). For Drop Jumps an optical detection (Opto Jump)
was used to measure the ground contact time. The test persons had to start of a 30 cm step
and had to jump single leg over a 24 cm hurdle as fast as they could. For the bodyscan, a Vitus
3D Body Scanner (300 dots per cm2) had been used.
Results & Discussion
The 3D motion capturing data will be used to analyse the joints and rotation of knee and ankle.
Gait graphs will be created to compare them with normal standard values for prevention and
also to compare further analysis with the status quo. Maximum strength data showed enormous differences between quadriceps and hamstring of the player. This data could be combined with 3D anthropometric data to see if there are any correlations. Additionally contact time of the drop jump could be added and will be used as indicator for rehabilitation and determining the health status of the player.
Conclusion
Further research will show if healthy reference patterns could be useful and how they could be
used in sport practice. After that, the influence of such data in prevention and rehabilitation
has to be evaluated and should be extended to adult players as well. HRP could help medical
professionals to get long-term information and get an impression of the players condition before the injury happened.
