The Isometric Mid-Thigh Pull (IMTP) has the athlete grip an immovable barbell set at mid-thigh height and pull maximally for 3–5 seconds, recording the force output on a force plate. Peak force (PF), force at 50/100/200 ms (early force production), and the rate of force development (RFD) are the main outcomes.
Because the test is isometric (no movement) and brief, it's safe to repeat frequently and produces low fatigue — IMTP can be re-tested weekly or even daily for monitoring readiness. It's a popular alternative to 1RM testing for peak-force tracking.
Pair IMTP peak force with a ballistic test (typically CMJ peak force) to compute the Dynamic Strength Index (DSI), which indexes how much of the athlete's max strength they can express ballistically.
Where it's used
High-performance S&C labs and pro sport with force-plate access; ideal for monitoring strength qualities without 1RM fatigue.
