      <subfield code="a">The critical force of a muscle  (the relative force below which an isometric contraction can be maintained for a very long time without fatigue) is comprised of between 15 and 20% of its maximum voluntary contraction (MVC). However, some authors believe that the value is below 10% MVC. Twelve healthy untrained participants carried out two isometric contractions with the digit flexors</subfield>
