Test-Retest Reliability and Concurrent Validity of the Isometric Mid-Thigh Pull as a Measure of Total Body Muscle Performance in Recreationally Active Adults

Measuring muscle performance is a common objective for many clinicians. However, many available testing measures are imprecise, resource prohibitive and designed to measure single, isolated joints [1-4]. Therefore, it is difficult to accurately assess the effectiveness of interventions designed to improve strength and power as they relate to function. At best, clinicians use surrogate measures of total body muscle performance such as grip strength, sit-to-stand movements and broad jumps. Each targets a different aspect of performance – strength, endurance, or power – and none incorporates the entire kinetic chain.
