- The study assessed shoulder rotational mobility, dynamic stability, and isometric strength in elite and national-level tennis players.
- Significant anthropometric differences were found between the National-Level Female Group (NFG) and other groups.
- National-Level Male Group (NMG) showed reduced external rotation in the dominant shoulder compared to NFG and Elite Male Group (EMG).
- EMG exhibited significant asymmetries in external rotation between dominant and non-dominant shoulders, likely due to higher training volumes.
- No significant differences in isometric strength were found across groups, but NFG had lower internal rotation strength and ER/IR ratio asymmetry.
- Dynamic stability scores were low, with asymmetries between dominant and non-dominant sides.
- The findings suggest the need for targeted training to address asymmetries and enhance dynamic stability.
- Future research should include more participants and explore associations with performance metrics like serve speed and playing style.
