Kinanthropometry is defined as the study of human size, shape, proportion, composition, maturation, and gross function, in order to understand growth, exercise, performance, and nutrition.
[1] It is a scientific discipline that is concerned with the measurement of individuals in a variety of morphological perspectives, its application to movement and those factors which influence movement, including: components of body build, body measurements, proportions, composition, shape and maturation; motor abilities and cardiorespiratory capacities; physical activity including recreational activity as well as highly specialized sports performance.
On the other hand, this definition omits some important objectives of quantifying the body that are an indelible part of its frame; for example: the study of human shape using the method of the anthropometric somatotype of Carter and Heath (1990).
Stewart (2010) defined kinanthropometry as "The academic discipline that involves the use of anthropometric measures in relation to other scientific parameters and/or thematic areas such as human movement, physiology or applied health sciences".
For Betancourt (2009), kinanthropometry is a scientific discipline of biomechanics that can be defined as: the set of theoretical assumptions that explain the relationships between the morpho-functional structure of healthy individuals and their biological potentiality of performing an efficient motion in an ontogenic moment.
