Mean values ± SEM; TF/μm², number of thick filaments per μm² within myofibrils; TF/myofibril, number of thick filaments per myofibril, calculated by multiplying myofibril areas by TF/μm²; (n), number of fields counted for Total myofibril area and TF/μm² values, number of sarcomeres measured for Sarcomere length and A-band length values, and number of myofibrils for Myofibril area values.

p < 0.05 compared to corresponding PwMhc2 value.
