Motor Control

Trail running is an emerging endurance discipline. Unveiling differences in motor adaptation between more (MP) and less (LP) proficient athletes represents the first step to I) standardize injury prevention protocols and II) optimize training. The aim of this work was to compare MP and LP trail runners for coordination and coordination variability (CV). Twenty athletes carried out a field test wearing a full body motion capture system. Coordination and CV were assessed for three couplings: I) knee-ankle, II) hip-knee and III) trunk-hip. No differences were found in coordination, but MP runners showed higher hip-knee and trunk-hip CV in downhill sections, as well as higher hip-knee CV in uphill sections. Results indicate superior motor adaptability for MP runners in an unpredictable environment. Future studies may assess whether specific techniques (balance and perturbation training) positively impact CV trail running population.
