Fast muscles, such as the thigh muscle in a sprinter, deliver energy quickly but fatigue quickly. Slow muscles, such as the soleus muscle in the lower calf, are less forceful but important for posture and endurance. Researchers from the University of Texas Southwestern Medical Center and Virginia Tech have discovered one gene regulator that maintains the fast muscle type and inhibits the development of a slow muscle type.
