What does the term "load" in relation to tissue properties refer to?

The term "load" in relation to tissue properties specifically refers to the outside force acting on tissue. In biomechanics, load represents the forces or loads that are applied to the body or its tissues, resulting from activities such as weight-bearing, physical exertion, or external impacts. Understanding this concept is crucial because it helps athletic trainers assess how external forces can affect the integrity and function of tissues, which can lead to injuries if the load exceeds the tissue's capacity. By recognizing what load means, athletic trainers can better design training programs and rehabilitation strategies that consider the limits and resilience of various tissues under different stressors.
