Sophia Human Biology Milestones 2 Sophia Human Biology Milestone 2 1 Which of the following statements is true of the effects of aerobic exercise on the muscle? Aerobic exercise leads to stronger muscles that sustain activity for short periods of time. Aerobic exercise significantly increases myofibrils within the muscles. Aerobic exercise leads to significantly larger muscles. Aerobic exercise increases mitochondria within cells, making muscles able to sustain activity for longer period...
