Research on Physical Fitness and Flatfoot in Children

Condition(s) studied

Investigational drug(s) / intervention(s)

No intervention (observational study): This is an observational study with no intervention.

Study summary

This study aims to explore the relationship between children's physical fitness and flatfoot. Specifically, it is designed to determine whether fitness levels are linked to the incidence and severity of flatfoot and to explore other possible factors, including genetics, exercise behavior, and body weight.

Eligibility

Primary outcome measure(s)

• Questionnaire Score — Baseline
  Score from a self-designed questionnaire on lifestyle habits and foot-related symptoms. Scale range: higher scores = better habits, fewer symptoms.
• Body Fat Percentage — Baseline
  Body fat percentage measured using InBody analyzer. Unit: Percent (%) (lower values indicate better body composition).
• Skeletal Muscle Mass — Baseline
  Skeletal muscle mass measured using InBody analyzer. Unit: Kilograms (higher values indicate greater muscle mass).
• Cardiorespiratory Endurance — Baseline
  Performance on standardized shuttle run test. Unit: Seconds (shorter time indicates better endurance).
• Handgrip Strength — Baseline
  Grip strength measured using digital dynamometer. Unit: Kilograms (higher values indicate greater strength).
• Pinch Strength — Baseline
  Pinch force measured with a pinch gauge. Unit: Kilograms (higher values indicate greater strength).
• Flexibility Test — Baseline
  Sit and reach distance measured in centimeters. Unit: Centimeters (higher values indicate greater flexibility).
• Balance Ability — Baseline
  Time maintaining one-leg stance without support. Unit: Seconds (longer time indicates better balance).
• Arch Index — Baseline
  Foot arch index derived from footprint analysis. Unit: Ratio (0.2-0.3 indicates normal arch).
• Achilles Tendon Alignment — Baseline
  Deviation angle of Achilles tendon alignment. Unit: Degrees (smaller angles indicate better alignment).
