AB  - Motor unit (MU) recruitment patterns were studied during dynamic and static 
      contractions at workloads corresponding to 10% of maximal voluntary contraction 
      force. The dynamic contraction consisted of a 20 degrees flexion and extension of 
      the elbow performed with a velocity of 10 degrees/s. Motor unit potential trains 
      were recorded from the brachial biceps muscle of 6 healthy females using a 
      quadripolar needle electrode and a computerized decomposition program. Properties 
      of the identified MUs were derived from concentric needle EMG. A total of 119 MUs 
      were identified during dynamic contractions, 107 MUs during static anisotonic 
      contractions, and 96 MUs during static isotonic contractions. The main result was 
      that MUs recruited during different contractions showed similar properties and 
      may belong to the same part of the motoneuron pool. This indicates that MU 
      recruitment patterns during dynamic contractions may be almost as stereotypical 
      as during static contractions and may even activate the same MUs.
