 Active children = children doing additional regular sports activity after school.
 Normal children = children doing no additional sports activity after school.
 PPT = pressure pain threshold (kg/cm^{2}).
 % PPT difference at A = [(PPT at C)  (PPT at A)]/(PPT at C) × 100%
 % PPT difference at B = [(PPT at C)  (PPT at B)]/(PPT at C) × 100%
