1 Participating clubs
As a consequence of the unscheduled break in European football due to COVID-19, this
season report contains results from July to March of the 2019/20 season for 20 teams that all
participated in the group stage of the UEFA Champions League. The following teams have
been included: AFC Ajax, Bayer 04 Leverkusen, Borussia Dortmund, Chelsea FC, Club Atlético
de Madrid, Club Brugge KV, FC Barcelona, FC Bayern München, FC Shakhtar Donetsk, FC
Zenit, Galatasaray AS, GNK Dinamo Zagreb, Juventus, KRC Genk, Manchester City FC,
Olympique Lyonnais, Paris Saint-Germain, SL Benfica, SSC Napoli, Tottenham Hotspur FC.
2 Presentation
The report is divided into nine sections, with data on exposure, general injuries, training
injuries, match injuries, severe injuries, muscle injuries, ligament injuries, re-injuries, and,
squad attendance/availability and absence. These sections contain data of the 2019/20
season from your club in comparison with other participating clubs described as means of
the data from July to March as well as specifically for each month. Each section also contains
historic data which gives you the opportunity to compare the current season with data from
your club and other participating clubs in previous seasons. The injury sections are generally
split into four sub-sections:
• Injury patterns: the relative distribution of injuries of this kind, looking at injury location,
type, overuse/trauma, contact/non-contact, severity and re-injury rate.
• Injury rate: the number of injuries of this kind relative to exposure time, allowing the
individual injury rate to be evaluated. Injury rate is expressed as the number of
injuries/1,000 hours of exposure.
• Days’ absence: the mean number of days lost because of injuries of this kind.
• Injury burden: a combined measure of the frequency (injury rate) and severity (days´
absence) of injuries of this kind giving the burden of injury for the player and the
consequences for the team. Injury burden is expressed as the number of days of
absence/1,000 hours of exposure. Example: Team A with 10 injuries in 5,000 hours, each
resulting in an absence of 10 days on average, has an injury burden of 20 days/1,000
hours. Team B with 20 injuries in 5,000 hours, each resulting in an absence of 5 days on
average, also has an injury burden of 20 days/1,000 hours.

3 Interpretation of results
When comparing your club’s results with those of other participating clubs, please bear the
following in mind:
• Because of the limited amounts of data collected over one season, the injury rates
presented are sometimes based on just a few actual injuries. This means that some results
should be interpreted with caution.
• The overall number of injuries varies between clubs, mainly because of the number of
minor injuries. It is therefore important to look not only at the overall injury rate, but also
at the data on severe injuries and squad availability, as these variables may have a greater
impact on the club.
• In the case of players who were still injured at the end of the season, we have used either
the club’s estimated return date or an approximation of severity based on the mean
absence for this particular injury. Some data on the number of days’ absence and injury
risk presented in the report could therefore be based on approximate values/estimates.
We hope that you will find this report useful in your daily work treating and preventing
injuries at your club. Please do not hesitate to contact FRG if you have any questions about
how to interpret the results.

4 Exposure
In total, 100 000 hours of exposure were recorded during the season, with approximately 85
000 training hours (85%) and 15 000 match hours (15%). Team x reported xx hours of total
exposure, with xx training hours (xx%) and xx match hours (xx%).
On average, teams reported 165 training sessions and 45 matches over the review period.
Since the reporting period differed between teams, we have also calculated a monthly
training and match load. On average, teams had 19 training sessions and 5.2 matches each
month, giving an average training-to-match exposure ratio of 5.3 hours of training for each
hour of match play.
