What is the primary goal when using NMES for strengthening?

• A. Submaximal contractions
• B. Isometric holds without movement
• C. Maximal tetanic contraction
• D. Random, alternating contractions

Answer: (C)

The goal is to produce a high-force, fused muscle contraction to drive strength adaptations. In NMES strengthening, this means eliciting a maximal (or near-maximal) tetanic contraction, where high-frequency stimulation keeps the muscle contracting smoothly and forcefully. This maximizes motor-unit recruitment and the torque the muscle can generate, providing the overload needed for strength gains. Submaximal contractions or isometric holds without movement don’t supply enough overload, and random, alternating contractions don’t deliver a consistent high-force stimulus. So, aiming for a maximal tetanic contraction best drives strengthening with NMES.
