We investigated the association of skin-fold thicknesses with total race time in 25 male mountain ultra-marathoners with 44.5 (7.0) years, 73.0 (7.8) kg body mass, 1.78 (0.07) m body height and a BMI of 22.9 (1.8) kg/m<sup>2</sup> in a 7-day mountain ultra-marathon over 350 km with 11,000 m of altitude. The relationship of skin-fold thickness and both intensity and volume during training with total race time as the dependent variable was investigated using multiple linear regression analysis. A significant association of the calf skin-fold with total race time was found (r<sup>2</sup> = 0.19, p &lt; 0.05). No relationship between skin-fold thickness and both average running speed and volume in training could be demonstrated. We concluded that the calf skin-fold showed a small to moderate association with total race time, however, the thickness of calf skin-fold was not related to training parameters.</p> ER -
