  1. Active children = children doing additional regular sports activity after school.
  2. Normal children = children doing no additional sports activity after school.
  3. PPT = pressure pain threshold (kg/cm2).
  4. % PPT difference at A = [(PPT at C) - (PPT at A)]/(PPT at C) × 100%
  5. % PPT difference at B = [(PPT at C) - (PPT at B)]/(PPT at C) × 100%
  6. a tested with Student's t-test.
