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.

Ankle Isometric Strength
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.
Time frame: Single assessment session
Ankle Proprioception
Ankle joint proprioception assessed bilaterally for the dominant and non-dominant limbs using a joint position sense test with a digital inclinometer. Proprioceptive accuracy is expressed as absolute error in degrees between the target and reproduced ankle joint position.
Time frame: Single assessment session
