How a soldier's load is carried can elicit different physical and physiological costs on the carrier. As such, this study aimed to profile and compare the impacts of three different load carriage backpack systems on physical and physiological outcomes during and following a load carriage march. Twelve soldiers were randomly allocated to one of three pack variants (Variant A, B, or C) using a Latin Square design and completed three 5 km load carriage marches (30 kg at 5.5 km/h) over three separate sessions wearing the different Variants for each march. Outcome measures during the march were heart rate and oxygen consumption and pre and post march were a counter movement jump, grip strength, and postural sway. There were no significant differences (p > 0.01) in any of the objective outcome measures across pack Variants. These results suggest that load weight will impact on the physical and physiological costs associated with load carriage to a greater extent than military backpack design.

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
