The final paper shows the importance between the correct and natural way of breathing and the neutral posture of the human body. A proper breathing pattern can affect the improvement of a person's posture, just as working on an ideal posture can improve and facilitate the breathing process. The function of the diaphragm is presented as the main muscle for inhalation and the pattern of diaphragmatic breathing as a natural and most efficient way to supply the human body with oxygen. The chapters in the paper describe the characteristics of a proper breathing pattern and the exercises used in kinesitherapy, which are based on the diaphragmatic breathing technique. The paper explains the connection between the location and the anatomical structure of the diaphragm in the human body, i.e. the insertion and origin of the muscle, as well as the positive effect that proper breathing has on the abdominal organs. The basic techniques for diaphragmatic breathing described in the paper should be basic exercises for correcting and re-establishing the most efficient breathing pattern, which is best known when a person is still a newborn. Relaxation exercises that have a positive effect on shortness of breath are also described, the progressive muscle relaxation technique, which can be done before all breathing exercises and is useful for the relaxation effect of overused muscles. All the exercises described in the paper can be done several times a day, which is recommended until diaphragmatic breathing becomes a regular habit.
