What is the definition of growth?

The definition of growth in the context of motor development primarily refers to an increase in physical size. This encompasses various aspects such as height, weight, and overall body structure. Growth can be measured and quantified through metrics like body mass index, growth charts, and physical assessments. It is a fundamental aspect of human development, particularly in childhood and adolescence, and indicates both biological processes such as cell multiplication and the hormonal influences that contribute to an individual's physical stature.

The concept of growth specifically focuses on the physical changes that occur over time, rather than the functional changes or competencies that might arise from these physical changes, which is why the inclusion of a definition emphasizing mere physical size is accurate. Thus, when discussing growth, it is essential to acknowledge that while functional capabilities do improve and evolve, the term itself is rooted in the tangible dimensions of the body rather than any qualitative enhancements in capability or function.
