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.
This study aims to examine the relationship between children's physical fitness and flatfoot. We will recruit a sample of children across different ages, genders, and fitness levels. Physical fitness will be assessed using standardized tests, including body composition, cardiorespiratory endurance, muscle strength, and flexibility. Foot structure and function will be evaluated through arch index and plantar pressure analysis to determine the presence and severity of flatfoot. Background information, such as age, gender, height, weight, exercise habits, and family history, will also be collected.

Questionnaire Score
Score from a self-designed questionnaire on lifestyle habits and foot-related symptoms. Scale range: higher scores = better habits, fewer symptoms.
Time frame: Baseline
Body Fat Percentage
Body fat percentage measured using InBody analyzer. Unit: Percent (%) (lower values indicate better body composition).
Time frame: Baseline
Skeletal Muscle Mass
Skeletal muscle mass measured using InBody analyzer. Unit: Kilograms (higher values indicate greater muscle mass).
Time frame: Baseline
Cardiorespiratory Endurance
Performance on standardized shuttle run test. Unit: Seconds (shorter time indicates better endurance).
Time frame: Baseline
Handgrip Strength
Grip strength measured using digital dynamometer. Unit: Kilograms (higher values indicate greater strength).
Time frame: Baseline
Pinch Strength
Pinch force measured with a pinch gauge. Unit: Kilograms (higher values indicate greater strength).
Time frame: Baseline
Flexibility Test
Sit and reach distance measured in centimeters. Unit: Centimeters (higher values indicate greater flexibility).
Time frame: Baseline
Balance Ability
Time maintaining one-leg stance without support. Unit: Seconds (longer time indicates better balance).
Time frame: Baseline

Arch Index
Foot arch index derived from footprint analysis. Unit: Ratio (0.2-0.3 indicates normal arch).
Time frame: Baseline
Achilles Tendon Alignment
Deviation angle of Achilles tendon alignment. Unit: Degrees (smaller angles indicate better alignment).
Time frame: Baseline
