RESUMO:

 

Introduction: in spite of the popularity of soccer at the youth level, data on the incidence of injuries in Brazil is limited. Muscle injuries are the most frequent in soccer, accounting for about 30% of all injuries. Although scientific knowledge on muscle injuries has increased in the last decade, the prevalence of these injuries has not decreased. Few studies on this field were dedicated to young soccer players, which highlights the need for further research. Objectives: to describe the incidence of injuries sustained by male elite youth soccer players over the 2017 season; to investigate the interaction between age, previous injury, match and training exposure and strength imbalances in the occurrence of muscle injuries in this population. Methods: demographic and anthropometric data, history of injuries, match and training exposure, and strength variables were recorded and analyzed. Injury incidence was calculated as the number of injuries occurred, divided by the number of hours of exposure on match play and training sessions, times 1,000. Players who sustained a non-contact muscle injury composed the injured group (IG) and players who suffered no non-contact injuries composed the uninjured group (UG). The relative risk was calculated and independent t-tests, the chi-square test and a multivariate logistic regression model were also conducted in the statistical analysis, considering P<.05. Results: one hundred and eighty seven injuries were documented in 122 players (65.2%). The overall incidence of injuries was 1.86 per 1,000 hours of exposure, with a rate six times higher in matches compared to training (P < .0001). Forty-five muscular injuries occurred in 34 players: 16 (36%) hamstring; 12 (27%) quadriceps; 14 (31%) adductor; and 3 (6%) calf injuries. The IG had a greater exposure to training [Mean Difference (MD) = 25.70 hours, 95% Confidence Interval (CI) = 1.12, 50.27, P = .041] and a greater overall exposure (match plus training) (MD = 32.97 hours, 95% CI = 6.22, 59.73, P = .016) than the UG. Regarding the time of arrival at the club, the IG presented a significantly smaller time of arrival in comparison to the UG (MD = - 6.57 months, 95% CI = 11.99, -1.18, P = .017). The muscle strength tests revealed that the IG had greater eccentric quadriceps strength (MD = 3.29 N / kg.100, 95% CI = 1.41, 5.17, P = .001), compared to the UG. The IG also had a lower hamstring:quadriceps strength (H:Q) ratio than the UG (MD = -5.24, CI95% = -8.84, -1.65; P = .005). Previous lower limb injury significantly increased the chance of sustaining a muscle injury (OR: 3.027, 95% CI = 1.133, 8.086). Conclusion: the risk of injury was higher during match play than during training and older players (U-20 years old) were the most likely to sustain injuries. Muscle injuries were the most prevalent and athletes with a previous history of lower limb injury, lower values of H:Q ratio and smaller time of arrival at the club, presented a higher risk of suffering muscle injuries. The interaction of both modifiable and non-modifiable risk factors seems to better explain the occurrence of injuries and this type of analysis should be continuously performed in the attempt to prevent injuries in adolescents.
