Stretch-Induced Force Deficit
Stretch-induced force deficit is temporary strength loss after long pre-effort static holds—why dynamic warmups beat marathon stretching before power tests.
Stretch-induced force deficit is the temporary drop in strength and power after long static holds—studies show reduced jump and sprint output when hamstrings or calves are held sixty seconds or more pre-effort. The effect fades as you move and ramp, but it matters on test days and between-interval starts.
Brief post-lift stretches rarely cause issues; pre-competition static marathons can. Favor dynamic prep before PR attempts.
Common questions
-
How long can you stretch before lifting without losing force?
Keep pre-lift static work under twenty seconds per muscle or skip it. Dynamic mobility and ramp sets restore output faster than sixty-second holds before heavy work.
