Question

1. what is anaerobic exercise?

Explanation:

Anaerobic exercise is a type of physical activity that involves short, intense bursts of movement where the body's demand for oxygen exceeds the oxygen supply available, leading to energy production without using oxygen (via anaerobic metabolism, like glycolysis). Examples include weightlifting, sprinting, and high - intensity interval training (HIIT). These exercises primarily target fast - twitch muscle fibers, help build muscle strength and power, and increase anaerobic capacity.

Answer:

Anaerobic exercise is physical activity involving short, intense bursts (e.g., weightlifting, sprinting) where energy is produced without oxygen (via anaerobic metabolism), targeting fast - twitch fibers to build strength/power and increase anaerobic capacity.
