AB  - The Xsens Link motion capture suit has become a popular tool in investigating 3D 
      running kinematics based on wearable inertial measurement units outside of the 
      laboratory. In this study, we investigated the reliability of Xsens-based lower 
      extremity joint angles during unconstrained running on stable (asphalt) and 
      unstable (woodchip) surfaces within and between five different testing days in a 
      group of 17 recreational runners (8 female, 9 male). Specifically, we determined 
      the within-day and between-day intraclass correlation coefficients (ICCs) and 
      minimal detectable changes (MDCs) with respect to discrete ankle, knee, and hip 
      joint angles. When comparing runs within the same day, the investigated 
      Xsens-based joint angles generally showed good to excellent reliability (median 
      ICCs > 0.9). Between-day reliability was generally lower than the within-day 
      estimates: Initial hip, knee, and ankle angles in the sagittal plane showed good 
      reliability (median ICCs > 0.88), while ankle and hip angles in the frontal plane 
      showed only poor to moderate reliability (median ICCs 0.38-0.83). The results 
      were largely unaffected by the surface. In conclusion, within-day adaptations in 
      lower-extremity running kinematics can be captured with the Xsens Link system. 
      Our data on between-day reliability suggest caution when trying to capture 
      longitudinal adaptations, specifically for ankle and hip joint angles in the 
      frontal plane.
