from C.T.V., MD of Spain:
I am a Spanish medicine doctor interested in bow shooting.
With the help of other bow shooters, we are trying to translate your article of the angular movement into Spanish, but we have some difficulties with the anatomical concepts you write in the article.
I would like to know the scientific names of the following:
When you describe the movement of the scapula to the backbone you say that it is a micro movement(and it looks like it were smaller than the movement of the chest bone to the chest joint, I can't understand that."
Chest bones - Ribs
Chest Bone - Sternum
During the expansion, which commences once we have reached holding, the tension increases in the lower back muscles creating a micro movement of the scapulae. Even though there is only a micro movement of the scapulae, through the Ratio of Circular Movement this micro movement translates into larger movements through the chest opening up, then through the shoulders and the arms (biggest movement). The Ratio of Movement is the result of correct back tension.
