The overall rowing-related injury rates per 1000 training hours and per 1000 training sessions by age and gender are shown in Figures 2 and 3. The overall injury rate per 1000 training hours was 0.46 (95% CI: 0.38-0.54), and the overall injury rate per 1000 training sessions was 2.16 (95% CI: 1.79-2.53). Among male rowing athletes, the injury rate was 0.37 (95% CI: 0.29-0.46) per 1000 h (\(\leq\)18 years: 0.35, 95% CI: 0.24-0.46; >18 years: 0.41, 95% CI: 0.26-0.55) and 1.77 (95% CI: 1.35-2.19) per 1000 training sessions (\(\leq\)18 years: 1.43, 95% CI: 0.98-1.89; >18 years: 2.48, 95% CI: 1.61-3.35). Among female rowing athletes, the injury rate was 0.62 (95% CI: 0.47-0.78) per 1000 h (\(\leq\)18 years: 0.42, 95% CI: 0.28-0.57; >18 years: 1.37, 95% CI: 0.87-1.86) and 2.85 (95% CI: 2.14-3.56) per 1000 training sessions (\(\leq\)18 years: 1.83, 95% CI: 1.20-2.45; >18 years: 7.85, 95% CI: 4.99-10.70). Based on the data of the 95% CI, female rowing athletes showed a significantly greater incidence rate per 1000 training hours than males, and female rowing athletes aged \(>\)18 years showed a significantly greater incidence rate than those aged \(\leq\)18 years and males, regardless of training hours and sessions. Using collinearity diagnostics, the VIF value between weight and BMI was 1.838; the VIF value between height and BMI was 1.838; hence, weight, height, and BMI were all used for analysis.
