The ISME Journal - Denitrifying community in coastal sediments performs aerobic and anaerobic respiration simultaneously Skip to main content Thank you for visiting nature.com.

During anaerobic respiration, the oxidation of glucose is incomplete. The reaction therefore releases much less energy – around a nineteenth of the energy released during aerobic respiration.

Your respiration and heart rate differ in aerobic activities versus anaerobic ones. Oxygen is your main energy source during aerobic workouts. You’re also using the energy from fat and glucose.

During anaerobic exercise, you burn calories and improve your cardiovascular health, just like during aerobic exercise. While the biggest benefit of anaerobic exercise is creating muscle mass ...

Anaerobic vs. Aerobic Exercise Aerobic means “with oxygen,” and anaerobic means “without oxygen.” Both are important for your overall health because they challenge your body in different ways.

Conversely, anaerobic training, which focuses on power and strength, can enhance the body's ability to generate force, leading to improved performance in both aerobic and anaerobic activities.
