What type of individual performs best under heavy load carriage?

Individuals with a sufficient aerobic base tend to perform best under heavy load carriage due to their enhanced cardiovascular and muscular endurance. This endurance allows them to sustain effort over extended periods while carrying weight. An adequate aerobic base indicates that the person has developed their cardiovascular system, enabling efficient oxygen delivery to the muscles, which is crucial when dealing with the physical demands of carrying heavy loads.

When individuals have a strong aerobic foundation, they can manage fatigue better, maintain a steady pace, and recover more quickly during the exertion involved in heavy load carriage. This capacity is essential for activities that require both strength and endurance, making a solid aerobic base a significant asset in such scenarios.
