Isometric Mid-Range Quad Hold

A pain-relieving isometric quadriceps exercise held at 60-70 degrees of knee flexion. Research shows long-duration isometric holds reduce patellar tendon pain immediately and provide a strength stimulus without aggravating reactive tendons.

  1. 01Sit on a chair or leg extension machine with your knee bent at approximately 60-70 degrees.
  2. 02If using a machine, set a light-to-moderate weight. If bodyweight, use a wall sit position at this angle.
  3. 03Contract your quad as hard as possible and hold the position without moving.
  4. 04Maintain maximum voluntary contraction for 30-45 seconds.
  5. 05The pain-relieving effect occurs during and immediately after the hold.
  6. 06Rest and repeat for the prescribed sets.
Why it matters

Isometric quadriceps contractions held for 30-45 seconds at 60-70 degrees of knee flexion have been shown to reduce patellar tendon pain by up to 70% immediately after the exercise. This cortical inhibition of pain allows runners to perform their run with less discomfort. Beyond the analgesic effect, the isometric load stimulates tendon adaptation without the compressive loading that worsens reactive tendinopathy.
