Extension of 3-year contract with AJAX

Extension of 3-year contract with AJAX

ACES Ajax

AJAX has recently extended the contract of Sports physician Hans Tol for a period of 3 years. The contract, which runs since 2018, is thanks to the high-quality top sport medical care that is offered by the Academic Center for Evidence-Based Sports medicine (ACES) of Amsterdam UMC, location AMC.

ACES combines multidisciplinary care of elite athletes with scientific research and education. Tol: “Within ACES we have very short lines of communication between sports medicine, Gino Kerkhoffs of sport traumatology and orthopaedics, Peter Struijs of paediatric orthopaedics, Mario Maas of sport radiology and Harald Jorstadt of sports cardiology. As a result, we can offer AJAX the best possible care 24/7. Additionally, medical professionals of AJAX have direct access to our education and profit from the insights that we attain through scientific research. Meanwhile, we manage to keep our feet planted in the mud of elite football. The experiences that we gain there is beneficial to all athletes under treatment in Amsterdam UMC.”

Scientific Research
The cooperation with AJAX has enabled ACES to make growth related injuries a research priority. Tol: “Until recently, little research had been done on this topic, despite certain injuries being career-limiting at a very young age. Osgood-Schlatter is such an example; an injury of the knee that frequently occurs in growing young boys. It is described as an innocent injury that is self-limiting. However, we suspect that this injury has many long-term consequences than is currently assumed. A torn cross ligament, that always receives plenty of attention, is likely less career limitating than growth related injuries.”

Sports physicians Amsterdam UMC
The daily sports medicine care at AJAX is in the hands of a large team. Besides Hans Tol, two other sports physicians of Amsterdam UMC are part of that team: Guus Reurink and Niels Wijne. The last two mentioned physicians are employed by AJAX for this purpose. Reurink, together with Tol, is responsible for all care associated with the youth selections. Additionally, they accompany the games of the Young-AJAX. This team, with the big, young talents, play in the so-called Keuken Kampioen Divisie (First Division). Niels Wijne is head of the medical staff at AJAX and accompanies the first team.

Orthopaedic Surgery basketball players

At the Academic Medical Center Amsterdam, the department of Orthopaedic Surgery is looking for basketball players (male and female) that would like to participate in scientific research to assess the efficacy of calf exercises on performance and the prevention of muscle injury.

As an athlete you want to improve performance and reduce the risk on injury. Former research has shown that an increase in calf muscle force can positively change the jumping height. With the application of a novel MRI technique, the researchers would like to visualize muscle characteristics to understand the mechanism of preventive exercises on muscle morphology in the calf muscles.

What does participation mean?
When the basketball player is contacted by the researchers a first MRI scan and intake is scheduled. The player is then randomized into one of the three groups: Interventiongroup A (Alfredson’s eccentric heel drop), Interventiongroup B (Concentric heel raise) or in a controlgroup (no intervention). The intervention period will take 12 weeks following an individual exercise plan. These exercises will cost no longer than 3 times 15 minutes per week. Travel expenses are reimbursed.

The exercises can be easily executed on the stairs or on a small elevation. If you are a female or male basketball players, 16 years or older, curious and excited to participate in this research? Sign up and let us know by sending an e-mail to l.s.bannink@amsterdamumc.nl or sign up via our website!
