  Hello,

I would like to estimate the number of motor unit of quadriceps in isometric knee extension using monopolar wire electrode, can anyone in this forum give me some hints on:

1. Minimal sampling rate and bandwidth
2. Optimal duration of isometric action
3. Maximal or submaximal? If submaximal muscle contraction is preferred, how many percentage of maximal voluntary contraction.
4. Any recommendation regarding the knee angle (knee angle related to muscle length)
5. Any recommendation on bit resolution on ADC

Why I ask this question, partly since I plan to equip some DAQ equipment but have a budget boundary.

Thanks a lot in advance.

Michael
