One of the multilevel analyses, linear mixed model, was used for showing the representativeness of each fiber subtype for each subject group.
Total fiber number = 212. Values are estimated as means ± SD. CSA = cross-sectional area, SF = specific force, Vo = maximum shortening velocity,
F = maximal contractile force.
