What is the bilateral deficit?

The bilateral deficit occurs when the force produced bilaterally is less than the sum of individual limb forces tested separately. This neural inhibition can range from 5-15% in most people.

Does the bilateral deficit matter for sports?

For most sports, unilateral training has advantages specifically because of the deficit. However, bilateral training provides unique strength adaptations and should not be eliminated entirely.

Can the bilateral deficit be reduced?

Yes, consistent heavy bilateral lifting (squats, deadlifts) reduces neural inhibition over time. Some elite powerlifters show bilateral facilitation rather than deficit.
