The change in body mass was not associated with the change in serum [Na+] (p >0.05). The change in body mass was related to both post-race serum [Na+] (Figure 2) and post-race serum osmolality (Figure 3) (p <0.05). The decrease of the volume of the lower leg was unrelated to fluid intake (p >0.05). Fluid intake was neither related to the changes in the thickness of adipose subcutaneous Mannose-binding protein-associated serine protease tissue nor to the changes in skin-fold thicknesses (p >0.05). Sodium intake was not related to post-race serum [Na+] (p >0.05). Post-race serum [Na+] was unrelated to both the change in the potassium-to-sodium ratio in urine and TTKG (p >0.05). The increase in serum urea was not related to the increase in serum osmolality (p >0.05). The change in serum urea was unrelated to the change in skeletal muscle
mass (p >0.05). The change in the thickness of the adipose subcutaneous tissue at the medial border of the tibia was significantly and positively associated with the change in creatinine clearance (r = 0.58, p = 0.025). The increase in the thickness of adipose subcutaneous tissue at the medial border of the tibia was not related to the non-significant change in skin-fold thickness of the calf (p >0.05). LBH589 in vivo Figure 2 The change in body mass was significantly and negatively related to post-race serum [Na + ] ( n = 15) ( r = −0.52, p = 0.045).
