Final answer:
Muscular endurance relies on both aerobic and anaerobic energy systems, making the statement false.
Step-by-step explanation:
Muscular endurance is the ability of a muscle or group of muscles to sustain repeated contractions over an extended period of time. It relies on both aerobic and anaerobic energy systems.
During low-intensity activities like long-distance running or cycling, aerobic energy metabolism primarily supplies the energy needed for sustained muscle contractions, making muscular endurance mainly dependent on aerobic energy. However, during high-intensity activities like weightlifting or sprinting, anaerobic energy metabolism also plays a significant role in meeting the energy demands.
Therefore, muscular endurance requires both aerobic and anaerobic energy systems, making the statement that it requires aerobic energy only false.
