Research Impact: Lower limb multi joint isometric testing has become increasingly popular in the past ten years. The isometric mid-thigh pull and isometric squat are two tests used in performance monitoring to test different strength qualities of an athlete. For example, peak force represents an athlete’s maximum strength capability. This review examined the reporting of reliability and normative data, the protocol used for the tests and the analysis techniques of the force-time curves. The criteria used to determine reliability, the method used to analyse the force time curve and the protocol for the tests differs across research and coaches should be aware of this before using certain variables or normative data associated with these variables. Peak force is the most reliable measure and can be used to determine maximum strength capabilities.
