What is the ramp time for strengthening?

1 second ramp up, 2 seconds at max, 1 second ramp down

0 ramp time with instant max contraction

2 second ramp up, 2 seconds at max, 2 seconds ramp down

2 second ramp up, 6 seconds at max, 2 second ramp down

Ramping for strengthening is about gradually bringing the electrical stimulus up to its peak, holding the contraction long enough to maximize muscle work, and then easing it back down smoothly. A 2-second ramp up lets the muscle start contracting gradually, reducing sudden, uncomfortable jolts. Holding at maximum intensity for 6 seconds provides a solid amount of time under tension, which helps recruit more motor units and promotes strength adaptations. A 2-second ramp down then ends the contraction smoothly and safely.

The other patterns either skip ramping entirely, which can be harsh on the muscle and skin, or shorten the time at max or stretch it unnecessarily, which can reduce the strengthening stimulus or increase fatigue without added benefit.
