Objectives: Injury and illness in elite national tennis programs can limit players' current and future performance. This study aimed to prospectively examine injuries and illnesses in an Irish elite national junior tennis program over 2 years. Methods: All injuries and illnesses that led to missed tennis training and match play in the Irish national junior tennis program (n = 82) over 2 years were collected in a prospective cohort study. Injury and illness prevalence and rates were calculated and reported with respect to gender and age group. Descriptive statistics were calculated for the type of illness and the region, location, type, nature, mechanism, and severity of injury. Results: Over the course of the study, 54% of players became injured, with 9.0% receiving more than one injury. Injuries were most frequent in the under-16 age group (12.93 injuries per 1,000 athletic exposures), compared to younger age groups (4.13 [U10], 3.43 [U12], 4.63 [U14] injuries per 1,000 athletic exposures) and seniors (1.98 injuries per 1,000 athletic exposures). Lower (49.5%) and upper limb (35.9%) injuries were frequent and mostly occurred due to overextension (35.9%). No significant differences in males and females injury rates were noted. However, females received a greater proportion of shoulder injuries (23.5% vs 10.9%), with more knee injuries in males (29.1% vs 7.8%). 0.52 illnesses per 1,000 athletic exposures were reported, with respiratory/cardiorespiratory (43.5%) most frequent. Injuries lead to greater average sessions lost (6.77 ± 11.56) than illness (1.83 ± 1.11). Conclusion: These findings can inform injury and illness preventative strategies to minimize absence from tennis play and should be prioritized in the under-16 group. Due to the different injury profiles between males and females, tailored preventative programs should be developed for males and females individually.
