Overview
Brief Summary
This observational cross-sectional study aims to profile ankle isometric strength and proprioception in 9-10-year-old junior ice hockey players and to compare these outcomes and limb symmetry indices with age-matched non-athlete children. Ankle isometric muscle strength is assessed using a handheld dynamometer, and ankle proprioception is evaluated using a digital inclinometer. Measurements are performed bilaterally for dominant and non-dominant limbs. Group comparisons and limb symmetry analyses are conducted to identify potential neuromuscular differences related to sports participation.

Arms & Interventions
Junior Ice Hockey Players
Children aged 9-10 years who participate in organized junior ice hockey training on a regular basis
Non-Athlete Children
Age-matched children aged 9-10 years who do not participate in organized sports or structured athletic training.
Outcomes
Primary Outcomes
Ankle Isometric Strength
Time Frame: Single assessment session
Ankle isometric muscle strength of the dominant and non-dominant limbs measured using a hand-held dynamometer (Lafayette Manual Muscle Testing System). Peak force values are recorded for dorsiflexion, plantar flexion, inversion, and eversion.
Secondary Outcomes
- Ankle Proprioception(Single assessment session)
