SUMMARY:

This work aims to study the fundamental principles that govern and control
human movement. To formulate a theory consistent with evolutionary principles
variational calculation methods and techniques from optimal control theory were used to propose
an organizational principle for the movement. The study carried out here restricts the analysis
for movement of the upper limbs of healthy individuals or those without motor pathologies
known. As part of the specific objectives of this work, we can mention the
deepening the study on the minimum start model proposed by Flash and Hogan,
as well as understanding the origin of the scale exponent initially studied by Hoff and
which exhibits a functional dependence between the duration of the movement and the magnitude of its
displacement. Although this model has been widely used due to its
ability to describe and represent the speed profile of movement, this work
argues that it does not have adequate physical or biomechanical foundations and proposes
alternative principles based on the optimization of other kinematic parameters. To the
In carrying out the study, the concept of decomposition of movement elements was used
proposed by Miranda to evaluate the correlation between the proposed theoretical models and the
experimental data collected.
