There are an infinite amount of potential assessments and movements that could be utilized, and Sparta is continuing to evaluate assessments and data with the goal to continue to grow our suite of practical, reliable, and valid assessment of human movement. The simplest answer as to why Sparta doesn't utilize more assessments is that any new assessment needs to first check these three boxes. While the Isometric Mid-Thigh Pull has been shown to be relatively reliable and valid in some of the literature, the practicality of the assessment is relatively poor. Sufficient familiarization, hardware set-up, time, and effort are needed in order to ensure that reliable and valid data is collected. For example, to ensure the test is a valid measure of global strength and not just a measure of grip strength, it is best practice to actually duct-tape individuals to rig or barbell. Poor practicality leads to infrequent data collection, which doesn't allow for enough volume and depth of data to determine meaningful trends, relationships, and thresholds for individuals to use.
