AB  - The aim of this study was to assess the agreement of three different automated 
      methods of identifying force-onset (40 N, 5 SDs, and 3 SDs) with manual 
      identification, during the isometric mid-thigh pull (IMTP). Fourteen 
      resistance-trained participants with >6 months experience training with the power 
      clean volunteered to take part. After three familiarisation sessions, the 
      participants performed five maximal IMTPs separated by 1 min of rest. Fixed bias 
      was found between 40 N and manual identification for time at force-onset. No 
      proportional bias was present between manual identification and any automated 
      threshold. Fixed bias between manual identification and automated was present for 
      force at onset and F(150). Proportional but not fixed bias was found for F(50) 
      between manual identification and all automated thresholds. Small to moderate 
      differences (Hedges g = -0.487- -0.692) were found for F(90) between all 
      automated thresholds and manual identification, while trivial to small 
      differences (Hedges g = -0.122--0.279) were found between methods for F(200) and 
      F(250). Based on these results, strength and conditioning practitioners should 
      not use a 40 N, 5 SDs, or 3 SDs threshold interchangeably with manual 
      identification of force-onset when analysing IMTP force-time curve data.
