What is Comparative analysis of fiber‐type composition in the iliofibularis muscle of phrynosomatid lizards (Squamata) about?

## Abstract The lizard family Phrynosomatidae comprises three subclades: the closely related sand and horned lizards, and their relatives the __Sceloporus__ group. This family exhibits great variation in ecology, behavior, and general body plan. Previous studies also show that this family exhibits great diversity in locomotor performance abilities; as measured on a high‐speed treadmill, sand lizards are exceptionally fast sprinters, members of the __Sceloporus__ group are intermediate, and horned lizards are slowest. These differences are paralleled by differences in relative hindlimb span. To determine if muscle fiber‐type composition also varies among the three subclades, we examined the iliofibularis (IF), a hindlimb muscle used in lizard locomotion, in 11 species of phrynosomatid lizards. Using histochemical assays for myosin ATPase, an indicator of fast‐twitch capacity, and succinic dehydrogenase, denoting oxidative capacity, we classified fiber types into three categories based on existing nomenclature: fast‐twitch glycolytic (FG), fast‐twitch oxidative‐glycolytic (FOG), and slow‐twitch oxidative (SO). Sand lizards have a high proportion of FG fibers (64–70%) and a low propor
