The PERT Study - Training Factors of PERformance and Injuries (PERT)
The goal of this observational study was to learn about injuries in professional football players and to find out whether daily monitoring data could help predict injuries. The study followed male players from the first team and the reserve team of a French first-division professional football club over one full competitive season.
The main questions were:
How often did injuries occur among players over the season? Which day-to-day changes in routinely monitored data were linked to the onset of a new injury (all injuries combined, intrinsic and extrinsic)? Were the results similar when looking only at intrinsic injuries?
Each day, the club's staff recorded each player's physical workload during training sessions and matches using tracking technology. Players also reported how they felt, including sleep, fatigue, mood, and pain. New injuries were recorded daily by the club's medical staff. Players took part through the club's usual daily monitoring, with no additional tests or visits.

Professional football players
Male players from the first team and the reserve team of a French first-division professional football club, followed daily over one full competitive season through the club's routine monitoring of external workload, self-reported wellness and injury status. |
No intervention was assigned. Data came from the club's usual daily monitoring: external workload measured by tracking technology during training sessions and matches, and self-reported sleep, fatigue, mood, pain and perceived intensity. |

Injury prevalence and occurrence of new injuries
Tidsramme: Daily from June 26, 2023, to May 19, 2024 (47 weeks).
|
Daily injury status (non-injured or injured) recorded by the club's medical staff, used to describe season-long injury prevalence. |
Daily from June 26, 2023, to May 19, 2024 (47 weeks).
|
|
Player characteristics
Tidsramme: Daily from June 26, 2023, to May 19, 2024 (47 weeks).
|
Age (years), professional status (reserve team or professional), playing position (defender, midfielder or forward) and number of previous injuries (0, 1 or ≥2), examined as putative factors associated with injury occurrence. |
Daily from June 26, 2023, to May 19, 2024 (47 weeks).
|
|
External workload
Tidsramme: Daily from June 26, 2023, to May 19, 2024 (47 weeks).
|
Measured by tracking technology during training sessions and matches: match exposure (yes or no), session duration (minutes), total distance covered (km), number of accelerations and decelerations per day, distance covered (m) and number of sprints per day at 80-90% and 90-100% of each player's individual maximal speed. Examined as putative factors associated with injury occurrence. |
Daily from June 26, 2023, to May 19, 2024 (47 weeks).
|
|
Self-reported wellness and perceived exertion
Tidsramme: Daily from June 26, 2023, to May 19, 2024 (47 weeks).
|
Sleep time (hours/day), sleep quality (1 = best to 7 = worst), mood (1 = best to 7 = worst), fatigue (1 = min to 7 = max), pain (1 = min to 7 = max) and perceived exertion (1 = min to 10 = max). Examined as putative factors associated with injury occurrence. |
Daily from June 26, 2023, to May 19, 2024 (47 weeks).
