Changes in single skinfold thickness in 100 km ultramarathoners It is well known that long to very long endurance charges lead to a decrease in body fat.It comes to a decrease in the subcutaneous grease layer, whereby no one has been investigating which skin fold thicknesses remove the most. We studied at 219 100 km runners at which parts of the body remove the skin folds. After 100 km, the runners decreased only 0.2 kg to fat, while the muscle mass returned by 0.7 kg.The skin folds adopted at the upper body (transition shoulder to chest) by 0.1%, at the waist by 1.8% and at the calendar by 0.8%. The percentage decrease in the skin fold thickness was smaller than long-distance wheels or long-distance swimmer was found.
