AB Background: Understanding fatigue mechanisms is crucial for exercise performance. However,scientific evidence on non-invasive methods for assessing fatigue in trail running competitionsis scarce, especially when vertical kilometer trail running races (VK) are considered. The mainpurpose of this study was to assess the autonomic nervous system (ANS) activity (i.e., central fatigue)and the state of muscle activation (i.e., peripheral fatigue) before and after a VK competition.Methods: A cross-sectional pilot study was performed. After applying inclusion/exclusion criteria,8 recreational male trail runners (31.63   7.21 yrs, 1.75 m   0.05 m, 70.38   5.41 kg, BMI: 22.88   0.48,running experience: 8.0   3.63 yrs, weekly training volume: 58.75   10.35 km) volunteered toparticipate and were assessed for both central (i.e., via heart rate variability, HRV) and peripheral(via tensiomyography, TMG) fatigue before and after a VK race. Results: After the VK, resting heartrate, RMSSD (p = 0.01 for both) and SDNN significantly decreased (p = 0.02), while the stress scoreand the sympathetic-parasympathetic ratio increased (p = 0.01 and p = 0.02, respectively). The TMGanalyses suggest that runners already suffered peripheral fatigue before the VK and that 20–30 minare enough for muscular recovery after the race. In summary, our data suggest that participantsexperienced a pre-competition fatigue status. Further longitudinal studies are necessary to investigatethe mechanisms underlying fatigue during trail running races, while training periodization andtapering strategies could play a key role for minimizing pre-competition fatigue status
