Abstract

L'invention porte sur un appareil d'étirement et sur un procédé d'étirement, lesquels permettent l'étirement pour une souplesse musculaire accrue et pour l'élargissement de la plage de mouvement d'articulations. La présente invention comporte une partie d'oscillation (60) qui oscille en fonction du mouvement d'une partie mobile qui est une partie parmi des parties du corps de l'opérateur que l'opérateur souhaite étirer, et un mécanisme à ressort (70) comportant un ressort mécanique (80) qui est amené à s'étirer ou à être comprimé par l'oscillation de la partie d'oscillation (60), et qui est amené à générer une force de ressort provenant de cet étirement et de cette compression. La présente invention est caractérisée en ce que le ressort mécanique (80) a une relation caractéristique avec un ressort musculaire (ressort musculaire est un terme utilisé lors de la comparaison des muscles de l'utilisateur à un ressort), et la relation caractéristique est une relation dans laquelle, dans un cas où une force de ressort générée par l'oscillation de la partie d'oscillation (60) est stockée dans le ressort mécanique (80), le ressort musculaire se relâche et la force de ressort du ressort musculaire est relâchée, tandis que, dans un cas où la force de ressort du ressort mécanique (80) est relâchée, le ressort musculaire est étiré et une force de ressort est stockée dans le ressort musculaire.
