AB  - James, LP, Roberts, LA, Haff, GG, Kelly, VG, and Beckman, EM. Validity and 
      reliability of a portable isometric mid-thigh clean pull. J Strength Cond Res 
      31(5): 1378-1386, 2017-This study investigated the test-retest reliability and 
      criterion validity of force-time curve variables collected through a portable 
      isometric mid-thigh clean pull (IMTP) device equipped with a single-axial load 
      cell. Fifteen males with >/=6 months of resistance training experience attended two 
      testing sessions. In each session, participants performed an IMTP in 2 separate 
      conditions in a randomized counterbalanced manner. The criterion condition 
      consisted of a closed-chain IMTP configured with a force plate (IMTPf), whereas 
      the experimental test was undertaken using a portable IMTP with data acquired 
      through a single-axial load cell (IMTPl). A very high reliability (coefficient of 
      variation [CV] = 3.10, 90% confidence interval [CI]: 2.4-4.6%; intraclass 
      correlation coefficient [ICC] = 0.96, 90% CI: 0.90-0.98) and acceptable validity 
      (CV = 9.2, 90% CI: 7-14%; ICC = 0.88, 90% CI: 0.71-0.95) were found in the 
      experimental condition for the measure of peak force. However, significant 
      differences were present between the IMTPf and IMTPl (p < 0.0001). Alternate 
      force-time curve variables did not reach acceptable levels of validity or 
      reliability in the experimental condition. The IMTPl is a valid and highly 
      reliable method for assessing peak force. This provides evidence supporting the 
      use of an IMTPl as a cost-effective and portable alternative for those who wish 
      to assess maximal force production in a similar fashion to a traditional IMTP. 
      However, practitioners should be aware that these are slightly different tests.
