Background: The Aspetar Sports Injury and Illness Prevention Programme introduced the Aspetar IP 2 NetWork, a customizable injury prevention programme for professional football clubs in Qatar during the 2020/2021 season. It includes 23 focus areas selected by stakeholders to prevent sports-related health issues., Objective: To assess the real world implementation of the IP 2 NetWork preventive focus areas during the first season after introduction, focusing on team adoption and player compliance., Methods: A survey was conducted among team physicians, physiotherapists and fitness coaches from the 18 professional football clubs in Qatar. The survey examined the implementation of the IP 2 NetWork focus areas and the roles of the different professionals in managing these areas., Results: 17 out of 18 clubs reported using IP 2 focus areas, applying an average of 11.4 areas (range 4-21). The most commonly used strategies were the Nordic hamstring exercise, cold water immersion, taping and concussion prevention. Team physicians led 38% of the focus areas, followed by physiotherapists (25%) and fitness coaches (24%), with 11% managed collaboratively. Fitness coaches primarily handled exercise-based areas like warm-ups and load monitoring. Preventive measures were applied to the full squad in 81% of cases, with 19% targeting at-risk players. Player compliance was high, with 86% of focus areas adopted by all or most players, rising to 97% for players identified to be at greater risk of injury or illness., Conclusion: Implementing the IP 2 focus areas was widespread among teams in Qatar, with strong collaboration between medical staff. Player compliance, especially among at-risk players, was excellent, demonstrating the programme's feasibility and effectiveness in real-world settings., Competing Interests: None declared., (Copyright © Author(s) (or their employer(s)) 2025.

Prospectively collected injury surveillance data are essential for designing and implementing injury prevention programmes. We investigated the incidence, characteristics and patterns of professional football injuries in Qatar, providing details on the most observed injuries' burden. We prospectively recorded individual time-loss injuries and training/match exposure from 17 professional football teams in Qatar during 8 seasons (2014/15 to 2021/22). Injury definitions and data collection procedures followed the 2006 consensus statement and results reported according to the 2020 IOC consensus statement on football injuries and methodology of epidemiological studies on injuries, respectively. In total, 1466 players with 4789 registered injuries were followed. The overall injury burden was 129 [95% CI: 128-130] days/1000 h. Over the 8 seasons there was a significant decreasing trend in the incidence of gradual onset injuries (p = 0.0012) and a non-significant decreasing trend for suddenonset match injuries (p = 0.063). The injury burden for match injuries was greater than the burden resulting from training injuries (460 [95% CI: 460-460] vs 56 [95% CI: 55-57] days/1000 h, p < 0.0001). There was no difference in time loss between index and recurrent injuries. Hamstring muscle strain represented the most frequent injury with a median of 11 (inter-quartile 5-20) days to return to play (RTP). ACL complete tear was the most impactful injury, in term of return to play, with a median of 200 (116-253) days to RTP. Re-injuries constituted 10.8% (4.7% of exacerbations). Mean illness incidence was 1.1 (SD = 0.4) illness/1000 hours, representing 5 illnesses per squad per season, with no variation over time. Qatari professional football is characterized by an overall injury pattern and risk similar to Asian and European norms. There was a significant decreasing trend in the incidence of gradual onset injuries and a non-significant decreasing trend for sudden-onset match injuries., Competing Interests: The authors declare no conflict of interest., (Copyright © Institute of Sport – National Research Instutite.)

Objectives: To compare injury incidence, burden and characteristics between the pre- and post-COVID-19 lockdown periods in Qatari professional football., Design: Prospective cohort study., Methods: Injury and exposure data for two post-COVID-19 lockdown periods [early post-lockdown period: short-term ~2 months (54 matches) and late post-lockdown period: long-term 8-months (183 matches)] were compared to the benchmark of the same periods from the three previous seasons (2017/18-2019/20)., Results: We observed no difference in overall, training or match incidence between early post-lockdown period and the benchmark reference. However, this short-term period resulted in lower burden for overall- (RR 0.80, P < 0.0001), training- (RR 0.73, P < 0.0001) and match-injuries (RR 0.40, P < 0.0001) compared to the benchmark. During late post-lockdown period match injury incidence (RR 0.72, P = 0.0010) and match injury burden (RR 0.69, P < 0.001) were lower than the benchmark. In contrast, both overall- (RR 1.30, P < 0.001) and training-injury burden (RR 1.65, P < 0.001) were higher. A significant increase in adductor strains in both post-lockdown periods was observed., Conclusions: Immediately after the COVID-19 lockdown (short-term effect), there was no difference in injury incidence but a lower injury burden compared to benchmark. Moreover, the rapid return to competition for the successive season (long-term effect) was associated with a higher overall- and training-injury burden, but a lower match-injury burden compared to the benchmark., Competing Interests: Declaration of Interest Statement The authors—Karim Chamari, Yorck Olaf Schumacher, Mokhtar Chaabane, Raouf Nader Rekik1, Souhail Chebbi, Ramadan Daoud, Lena Kristin Bache-Mathiesen, Khalid Alkhelaifi, Roald Bahr, Montassar Tabben—declare that they have no competing interests., (Copyright © 2023 Sports Medicine Australia.

To assess the mechanisms of ACL injury in male professional football players in Qatar across multiple seasons using systematic video analysis. 15 ACL injuries occurred in competition among the professional football teams that participated in an injury Surveillance Programme during 6 seasons (2013/2014 to 2018/2019). High-definition broadcast videos of these injuries were analyzed (49 views; 34 slow motion) by five analysts who independently described the injury mechanisms (situation, behavior, biomechanical characteristics) using validated observational tools. A knee valgus mechanism was observed in two-thirds of the cases (1 with direct contact to the knee, 3 with indirect contact (other body parts) and 6 with no contact). No visible valgus was reported in 2 of the direct knee contact injuries, while 3 cases of non-contact and indirect contact injuries were unclear. We observed 4 main categories of injury situation among those (n = 12) classified as non-contact/ indirect contact (multiple combinations were possible): pressing (n = 6), tackling or being tackled (n = 4), blocking (n = 3) and screening (n = 2). Direct contact injuries (n = 3) were suffered by 2 players during tackling and 1 whilst being tackled. Contact injuries represented only 20% of ACL injuries occurring during competition in Qatari professional soccer players. Independent of the playing situation, knee valgus was frequently observed (10/15 cases). Pressing was the most common situation (6/15 cases) leading to injury. Landing after heading was not reported in any of these ACL injuries., Competing Interests: The authors declare having NO conflict of interest., (Copyright © Biology of Sport 2023.)

Aim: To ascertain ACL injury incidence, severity (injury burden) and patterns (contact/non-contact and reinjuries) in a professional male football league in the Middle East over five consecutive seasons., Methods: Prospective epidemiological study reporting ACL injuries in professional male soccer players in the Qatar Stars League, with complete matches/training exposure over five seasons (2013-2014 to 2017-2018), corresponding to 2243 player seasons and 729 team months., Results: 37 complete ACL ruptures occurred in 37 players during 486 951  hours of player exposure. The overall ACL injury rate was 0.076 injuries/1000  hours of exposure (season range 0.045-0.098). Injury incidence during matches and training was 0.41 and 0.04 injuries/1000  hours of exposure, respectively. Match injury incidence was greater than that of training (OR 11.8, 95%  CI 6.21 to 23.23, p<0.001). Average injury-related time-loss following ACL injury was 225 days±65 (range 116-360). Overall injury burden was 16.3 days lost/1000  hours of exposure., Conclusion: The overall ACL injury rate in professional male soccer players competing in the Middle East was 0.076 injuries/1000  hours of exposure, match injury incidence was greater than training, while the average ACL time-loss was 225 days., Competing Interests: Competing interests: None declared.

Previous literature suggests that human behaviour and physiology are somehow altered by the moon-cycle, with particular emphasis on poorer sleep quality and increased aggressive behaviour during full moon. The latter variables can negatively impact athletes' recovery and increase the likelihood of injury resulting from collision with another athlete. Therefore, the current study aimed to investigate the association between the lunar cycle and injury risk in professional football players (soccer). We monitored injuries and player exposure in the premier professional league in Qatar during four consecutive seasons (2013-2014 through 2016-2017). Acute (sudden-onset traumatic) injuries (n = 1184; 587 from contact with another player and 597 without player contact) recorded during matches and training were classified according to the lunar cycle characteristics on the date of injury: (i) moon illumination, (ii) lunar distance from earth and (iii) tidal coefficient, acquired from the lunar calendar and tide tables. We used a Poisson regression model to examine the relationship between injury risk and lunar cycle characteristics. We did not detect any association between injury risk and moon illumination, earth-to-moon distance or tidal coefficient, not for all acute injuries, nor for contact and non-contact injuries when examined separately. The findings suggest that the full moon or new moon or the gravitational pull have no effect on football injuries. Thus, organisers need not consult moon or tide tables when planning future event schedules.
