Optimizing Load-Bearing


The decision to calculate an optimal load-bearing weight per man is a difficult task.
It is challenging to define an optimal load, since no “hump” is going to be conducted under
ideal conditions. Factors such as walking pace, weight carried, climate, grade, type of
terrain and clothing, etc., will all vary on any particular mission. Table 10-1 presents
factors essential for ensuring energy conservation and comfort. These factors combined
with proper physical training, will serve to optimize your load-bearing.

Common Medical


Conditions


A number of acute medical conditions are associated with load-bearing. Most are
minor, but any one can potentially affect your ability to maneuver quickly and ultimately
slow down the walking pace of the squad or platoon. By understanding the range of medical
problems, you will be able to better prevent, assess and treat these injuries. These medical
conditions are all covered in Chapter 12: Training and Sports Related Injuries. The most
common injuries incurred during load-bearing are:

Table 10-1. Optimizing Load Carriage


Loads should be close to the center of the body.

Distribute the volume and weight of the load proportionately
on the front and back of the chest.

Chest movement should not be restricted by the
load-bearing vest or rucksack.

Adjust the pack so that overloading or straining of muscles is avoided.

Maintain normal posture and walking patterns.

A large padded waistbelt spreads 80% to 90% of the
weight over the pelvic girdle.

Increase comfort by transferring most of the pack’s weight
to the waist belt by the use of a flexible frame.
