Body composition
fat-free mass, FM
THORACIC
Body composition was measured fasted in the morning based on air displacement plethysmography using a Bod Pod (Cosmed, Italy). Once the body density had been determined, the fat mass (FM) and fat-free mass (FFM) were calculated using the Siri equation. Thoracic lung volume was estimated using the Bod Pod software. During measurement, participants wore only a swimsuit and an acrylic swim cap. Repeatability of the BodPod measurements was previously determined as high [
