Isometric Mid-Thigh Pull (IMTP) test protocol

A maximal 3–5 second isometric pull from a static mid-thigh position on a force plate — measures peak force production without the fatigue of 1RM testing.

Last updated May 20, 2026

What it measures

Peak force (PF), force at 50/100/200 ms (rate of force development, RFD), and isometric strength capacity. Low-fatigue alternative to 1RM testing; safe to repeat weekly or even daily.

Equipment

  • Force plate (fundamental — IMTP is impossible without one)
  • Immovable barbell rig with the bar set at mid-thigh height (just above the patella)
  • Lifting straps to secure the grip during the maximal pull

Protocol

  1. Athlete stands on the force plate with bar gripped at mid-thigh height. Hip angle ≈ 145°, knee angle ≈ 145° (the standardized 'second pull' position).
  2. Athlete is cued to pull as hard and as fast as possible against the immovable bar for 3–5 seconds. Coach calls 'pull!' to start the trial.
  3. Force plate records peak force and the full force-time curve.
  4. 2–3 trials with 1–2 minutes rest. Best of 3 for peak force; report rate-of-force-development at 50/100/200 ms if you want the early force production picture.

Scoring

Peak force in newtons (N) or relative to bodyweight (N/kg). DSI (CMJ peak force ÷ IMTP peak force) is often computed from the same testing block.

Typical ranges

Elite male field sport peak force: 3500–4500 N (relative ≈ 40–55 N/kg). NCAA women's soccer: 2200–2900 N.
