AB  - The use of isometric strength testing, particularly the isometric mid-thigh pull 
      (IMTP) has increased dramatically over the last decade. The IMTP and isometric 
      squat (ISqT) provide one aspect of performance monitoring with variables such as 
      peak force and rate of force development being derived from the force-time curve. 
      The reliability of some of these variables is conflicting in the literature, and 
      the reporting of the reliability is not standardised across the research. The 
      majority of research only reports intraclass correlation coefficients with very 
      few studies reporting coefficient of variation and 90% confidence intervals. 
      Additionally, methods used to calculate variables from the force-time curve 
      differ across studies. An aim of muscle strength testing is to provide normative 
      values for specific sports, allowing coaches to distinguish between performance 
      levels or evaluate the effects of training on performance. This narrative review 
      aims to evaluate studies that have researched the reliability and/or reported 
      normative data for both tests. Additionally, the testing protocols and the 
      force-time curve analysis techniques utilised are discussed, concluding with 
      practical applications for coaches on the uses and limitations of these tests. 
      Results demonstrate that peak force is the most reliable measure and can be used 
      to determine maximum strength capabilities.
