Notes:
Nine out of 23 variables were selected for male swimmers.
OR, odds ratio; CI, confidence interval.
Arm means upper limb length (cm); Leg length A means iliospinale posterior height (cm); Torso length means acromion height—trochanterion height (cm); Leg length H means eristailiaca height (cm); Biceps circumference difference means maximum biceps circumference—minimum biceps circumference (cm).
