Objectives. The study aimed to compare the incidence of muscle injuries in the qualifying rounds, semifinals and finals in athletics.
Materials and Methods. A total of 14 male and 12 female athletes who participated in all rounds (preliminaries, semifinals, and finals) of the 100 m, 200 m, and 400 m matches were analyzed over a 4-year period starting in 2021-2024. The female athletes were aged 22.4 ± 3.81 years, with a mean height of 167 ± 8.6 cm, and weight — 64.6 ± 17.5 kg. The male athletes were aged 23.4 ± 3.82, having an average height of 169 ± 8.3 cm, and weight — 66.4 ± 15.8 kg. A t-test was used to conduct comparative assessment of performance between finals, semifinals, and preliminaries for each gender and event. A 95% confidence interval was calculated separately for each gender, event, and round. Additionally, incidence rates were compared. The significance level was accepted at p < 0.05.
Results. HMI (hamstring muscle injuries) incidence rate for female qualifiers was found to be 1.50 (1.05-1.95), semifinals — 1.33 (0.79-1.88), and the final — 1.91 (1.44-2.38). LLMI (lower limb muscle injuries) incidence rate among female qualifiers was 1.50 (0.58-2.42), semifinals — 1.00 (1.00-1.00), and the final — 1.55 (1.36-1.74). HMI incidence rate in male qualifiers was 0.50 (0.08-1.28), semifinals — 0.67 (0.77-2.10), and 1.00 (0.34-1.66) in the final. LLMI incidence rate for male qualifiers was 0.40 (0.28-1.08), semifinals — 0.24 (0.55-1.05), and the final revealed 0.60 (0.08-1.28).
Conclusions. The highest incidence of muscle injury in all forms among men was observed in the all-round category. In women, hamstring muscle injuries occurred in the final, while lower limb muscle injuries were most prevalent in the preliminaries and semifinals.
