May indicate training-related MHC shifts in elite female athletes; leaves open causality and performance relevance.
Does elite athletic training alter myosin heavy chain distribution in the gastrocnemius muscle of females compared to untrained individuals?
Elite female track athletes exhibit a unique and diverse myosin heavy chain phenotype with a high proportion of hybrid fibers, likely due to chronic and varied training.
Parcell et al. (2003) studied this question.
