Abstract

This study aimed to determine mountain ultra-marathon (MUM) performance factors in a large group of endurance mountain runners. Maximal aerobic speed (MAS) was assessed one week prior to the MUM. The level and graded (10%) energy cost of running, stiffness, knee extensors force (KE_f), and jump height on a counter movement jump (CMJ) were measured in 24 male ultra runners before (pre) and immediately after (post) the Interlacs Trail (75 km and 3 930/3 700 m d+/d−). Performance time was correlated with MAS (r=− 0.74, p<0.001), fraction of MAS (F_MAS) sustained (r=− 0.89, p<0.001), KE_f (r=− 0.51, p<0.05), and KE_f loss (r=− 0.51, p<0.05). A multiple regression analysis was performed using performance time in minutes (T) and the calculated individual characteristics, resulting in T=− 11.852×F_MAS−37.195×MAS−0.118×KE_f+2090.581 (R²=0.98, with 95% confidence interval). Contrary to expectations, performance was neither correlated to the level or uphill energy cost of running nor to the changes of these costs post-MUM. To perform in a MUM, training should take into account muscle strength of the KE, MAS and F_MAS.

Key words
