What is the common on:off duty cycle for NMES strengthening?

• A. 1:1
• B. 1:5
• C. 2:1
• D. 1:10

Answer: (B)

In NMES strengthening, you want contractions to be strong but not so fatiguing that you can’t train effectively. A longer rest period between contractions helps muscles recover and allows you to produce repeatable, meaningful contractions over a set. The common on:off duty cycle used for strengthening is 1:5. This means a short on-time is followed by a longer off-time, giving the muscle ample recovery between bursts. For example, 10 seconds on would typically be paired with about 50 seconds off. This balance supports repeated contractions and better strengthening while minimizing rapid fatigue. Other ratios aren’t as effective for building endurance and strength because they reduce recovery too much or waste time with too little work. A 1:1 ratio pushes fatigue more quickly; a 2:1 ratio is still fairly demanding; a 1:10 ratio may yield too little contraction time to drive strengthening.
