What is a documented benefit of FES bicycle systems?

• A. Increased VO2 max and increased muscle CSA
• B. Decreased VO2 max
• C. No change in muscle size
• D. Reduced endurance

Answer: (A)

FES bicycle systems provide a structured aerobic and strength-training stimulus to muscles that may not function voluntarily. When these systems are used regularly, the rhythmic, repetitive contractions of the leg muscles during cycling promote cardiorespiratory adaptations and muscle growth. This combination leads to a documented increase in VO2 max, reflecting improved maximal oxygen uptake, and an increase in muscle cross-sectional area due to hypertrophy from the ongoing loading of stimulated muscles. In contrast, outcomes like decreased VO2 max, no change in muscle size, or reduced endurance aren’t supported as typical benefits of FES cycling.
