Tennis Research Group


Tennis Research and Performance Group

Established January 2020

Sophiahemmet University

Tennis Research and Performance Group is based at and hosted by Sophiahemmet University, Stockholm, Sweden. It is a subgroup to the overall research group MUSIC (Musculoskeletal & Sports Injury Epidemiology Center) directed by professor Eva Skillgate.


The sport of tennis develops in many ways, most of them very positive. However, along with the development of early specialization in tennis the need for a uniform way of protecting players health, development and performance becomes more important. This statement is not only important when the players eventually reach the WTA or ATP level since those players might be the premium selection and “survivors of the fittest”. Therefore, we need to establish this from the level of Tennis Europe (under 14) and ITF Junior level (under 18) in order to improve the situation.


Therefore, the aim within our group is to:

(1) Establish long-term research programs on injury and disease prevention including studies on basic epidemiology, risk factors, injury mechanisms and high performance,

(2) Fostering collaborative relationships with individuals, institutions and organizations to improve tennis players’ health.
