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.

Outcome Measures

Primary Outcomes (1)

• 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.

  Single assessment session

Secondary Outcomes (1)

• Ankle Proprioception

  Single assessment session

Study Arms (2)

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.

Eligibility Criteria

• Age: 9 Years - 10 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17)
• Sampling Method: Non-Probability Sample

Study Population

The study includes 70 healthy children aged 9-10 years, comprising junior ice hockey players and age-matched non-athlete controls.

You may qualify if:

• Children aged 9 to 10 years.
• For the ice hockey group: regular participation in organized junior ice hockey training.
• For the control group: no participation in organized sports or structured athletic training.
• Ability to understand and follow test instructions.
• Written informed consent obtained from parents or legal guardians

You may not qualify if:

• History of lower extremity injury within the past 6 months.
• Previous ankle or lower limb surgery.
• Presence of neurological, musculoskeletal, or balance disorders that could affect ankle strength or proprioception.
• Current pain or injury affecting lower extremity function.
• Any medical condition that would limit safe participation in the assessments.
