Abstract
The domestic donkey (Equus asinus) has a very specific body construction. It is built in such a way that the mutual relationship of individual body regions enables great work endurance. The fact that this breed of domestic animal originates from wild ancestors, originated and developed in Africa, clearly shows that the breed developed in harsh climatic and ecological conditions that conditioned the appropriate biological response. The biostatic model causes the biodynamic effect, i.e., the production of biokinetic energy. Movement forwards occurs as a consequence of the creation of biokinetic energy and its transfer from the back part of the body, where it originates, to the front part of the body. The most efficient transfer of biokinetic energy is enabled by the existence of an appropriate biostatic model, i.e., body structure, and this leads to a biodynamic effect that is defined as a movement. For the process of movement, the muscles must be well developed. Two muscle groups are distinguished; a) pelvic muscles, b) external hip and croup joint muscles. The basic lever for the transfer of biokinetic energy is the femur. The generated energy is transferred from the hip joint to the thigh muscles, which shortening leads to the movement of the hind leg forward, its leaning against the ground and pushing the whole body forward. The generated biokinetic energy cause the bio kinematic effect, which is characterized as a movement.
