Clinical parameters, body composition and fat availability, exercise parameters, insulin sensitivity and MR-spectroscopy data in endurance trained athletes.

Values are indicated in mean ± SEM. BMI = body mass index; FFA = free fatty acids; suppression of EGP = suppression of endogenous glucose production = measure of hepatic insulin resistance; M-value = glucose infusion at high insulin dose = measure of peripheral (whole body) insulin resistance; IMCL = intramyocellular lipids; IHCL = intrahepatocellular lipids expressed as % of hepatic water signal; IMCL pre/IHCL pre = before exercise; IMCL post/IHCL post = post exercise; ΔIMCL/ΔIHCL = 2h-aerobic exercise induced changes of IMCL/IHCL; α = p-value
