Leg skinfold thicknesses and race performance in male 24-hour ultra-marathoners. For elitic runners from 100 m to the marathon, there is an association between skin fold thickness and competition time depending on the distance and gender. We have examined for 24-hour runners whether we can also find a correlation. Although correlations could also be found in the bivariate analysis, the skin fold thicknesses in the multivariance analysis showed no connection with the went kilometers, read below https://pubmed.ncbi.nlm.nih.gov/21566757/
