Gluteal Slow-vs-Fast Ramp Dispersion
Lie prone, forehead on stacked hands. Detect where the two responses differ — which fiber regions feel recruited in the fast version but not the slow, and where the slow version produces tension that the fast version skips over.
Full Lesson Notes
Complete Practice
Lie prone, forehead on stacked hands. Slowly contract and release the right gluteus through a slow ramp — three seconds up to mild tension, three seconds down. Now repeat with a fast ramp — half a second up, half a second down. The slow ramp follows the muscle's quasi-static force curve; the fast ramp excites its viscoelastic response. Detect where the two responses differ — which fiber regions feel recruited in the fast version but not the slow, and where the slow version produces tension that the fast version skips over. Challenge: Without instrumentation the contrast is qualitative; jaw-clench-style guarding may dominate the fast ramp and confound the dispersion reading.
