Which principle of efficient human movement involves maintaining stability?

Maintaining stability during movement is crucial for efficient manual handling, and the principle that best reflects this is utilizing the base of support. The base of support refers to the area beneath a person that has contact with the ground; a wider base of support generally provides better stability. When an individual has a stable stance, they can better control their movements, reduce the risk of falling or injury, and handle loads more effectively.

This principle is particularly important when lifting or carrying objects, as it ensures proper posture and alignment, allowing the individual to distribute weight evenly and maintain their center of gravity. By focusing on a stable base, a person can optimize their performance while minimizing the strain on their body, which contributes to safer manual handling practices.
