Epidemiology and clinical characteristics of football injuries among academy players in Ghana.

Abstract:

Objective: To determine the epidemiology and clinical characteristics of match and training injuries among football players at an academy in Ghana.

Methods: In this prospective observational study, we followed 80 youth and adult football players at a Ghanaian academy over a season of 39 weeks. Medical attention and time-loss injuries, as well as exposure times of players, were recorded by resident physiotherapists using a standardised injury surveillance form. The average weekly injury prevalence was calculated. Injury incidence rates were calculated per 1000 exposure hours, with significance indicated as 95% CIs.

Results: 126 injuries were recorded during the season, with an average weekly injury prevalence of 4.1%. The overall injury incidence was 4.5 (95% CI 3.8 to 5.4) injuries per 1000 hours with under 14 (5.8 (3.3 to 10.2)/1000 hours) and under 18 players (5.7 (4.4 to 7.4)/1000 hours) recording a higher incidence than under 16 (5.1 (3.5 to 7.4)/1000 hours) and senior players (2.7 (1.9 to 3.9)/1000 hours). Match injury incidence was 13 times higher than training injury incidence (27.4 (21.5 to 34.9) vs 2.3 (1.8 to 3.0) injuries/1000 hours). Injuries to the lower extremities had the highest incidence (3.9 (2.1 to 7.2) injuries/1000 hours), with the knee being the most commonly injured site (n=30, 23.8%). The most common type of injury was a joint sprain (1.9 (1.5 to 2.5) injuries/1000 hours), and the most common injury mechanism was direct contact with another player (1.5 (1.1 to 2.0) injuries/1000 hours). Most injuries were moderately severe (2.0 (1.5 to 2.6) injuries/1000 hours).

Conclusion: Ghanaian academy football players have a substantial risk of sustaining injuries, especially among younger players. Further studies should focus on developing specific injury prevention programmes in under-researched football-playing populations.
