  • All measures are controlled for final body mass. Muscle and tendon masses were divided by final body mass and the resulting numbers are dimensionless.

    For all significant differences, the exercised group is greater than the sedentary group (Mann-Whitney U tests). Exercised and sedentary pairs listed in bold are significantly different at P=0.05.

    n/a, not applicable.

    Values in parentheses are the interquartile range.

  • indicates an interquartile range of approximately zero.
