Official title
General Assessment of Strength and Mobility in Artistic Swimmers of the Spanish Swimming Federation
Overview
This cross-sectional observational study aims to establish reference values for joint mobility and isometric muscle strength in elite artistic swimmers across different competitive categories. The study will analyze inter-limb asymmetries and agonist-antagonist strength ratios in upper and lower limbs. Additionally, relationships between isometric strength, countermovement jump performance, and handgrip strength will be explored to assess their utility as functional performance indicators. Participants will be assessed during national team training camps using standardized, validated measurement protocols. The findings are expected to contribute to the identification of sport-specific functional profiles and potential injury risk factors in artistic swimming.
Interventions
- Other Standardized Functional Performance Assessment
Participants undergo a standardized, non-invasive functional assessment protocol conducted during national team training camps. The evaluation includes anthropometric measurements, photographic goniometry of shoulder and hip joint mobility, isometric muscle strength testing of upper and lower limbs using a validated force sensor, countermovement jump performance assessed on a contact platform, and handgrip strength measured with a digital dynamometer. All procedures are performed in a single ass
