Mary wants to enter a weight-lifting competition and consults you as to what type of muscle fibers she needs to develop and how she should go about it. What would you suggest to her?
What will be an ideal response?
Weight lifting requires anaerobic endurance. Mary would want to develop her fast fibers for short-term maximum strength. She would achieve this by engaging in activities that involve frequent, brief, but intensive workouts, such as with heavy weights to the point of muscle fatigue. The fatigue triggers the production of new myofilament proteins, leading to muscle bulk and strength.
