  • Values are means ± S.E.M. (N=6).

    Mb is body mass; Mm is the sum of the masses of all the leg muscles; Mm,j is the sum of the masses of the muscles that could possibly power jumping.

  • * Muscles excluded in calculating Mm,j.

  • For the iliofibularis, approximately 11 g representing the anterior portion of the muscle was excluded from calculation of Mm,j.
