# Epidemiology of Injury Compilants in Elite Sprinting Athletes in Athletics (Track and Field)
## 3 Results
### Injury Number and Prevalence  
A total of 302 injury complaints related to athletics activity were reported by 65 athletes of the 68 included athletes. The lifetime prevalence proportion was 95.6% (95% CI: 90.7 to 100.5%) (Table 1). Six athletes reported 1 injury, 10 athletes reported 2 injuries, 11 reported 3 injuries, 8 reported 4 injuries, 9 reported 5 injuries, 7 reported 6 injuries, 5 reported 7 injuries, 1 reported 8 injuries, 4 reported 9 injuries, 2 reported 10 injuries, 1 reported 11 injuries, and 1 reported 14 injuries (Figure 1).  
During the one-year period before the survey, 42 athletes reported having at least one injury complaint occurring during athletics. The 1-year prevalence proportion was 61.8% (95% CI: 50.2 to 73.3%) (Table 1). Eighteen athletes reported 1 injury, 14 athletes reported 2 injuries, 6 reported 3 injuries, 1 reported 4 injuries, 2 reported 5 injuries, and 1 reported 6 injuries (Figure 1).  
Eleven athletes reported having at least one injury complaint related to the athletics activity when filling out the survey. The point prevalence proportion was 16.2% (95% CI: 7.4 to 24.9%) (Table 1). Nine athletes reported one injury, one reported two injuries, and one reported six injuries (Figure 1).
