The invention discloses a training badminton ball provided with a guide ball and airflow passages. The badminton ball comprises a ball head and a ball apron which is connected to the tail of the ballhead, wherein a cross groove is kept in the center of the interior of the ball head; a spherical groove is kept in the center of the cross groove; a plane, where the cross groove is located, is perpendicular to a central axis of the ball head; the spherical groove is filled with the movable guide ball; and multiple groups of airflow passages are formed in the ball head from the topmost side to theperiphery. According to the training badminton ball provided by the invention, in one aspect, the guide ball and the airflow passages are mutually cooperated, and the badminton ball, due to motions of the guide ball and deflecting force caused by airflow in the airflow passages in a badminton ball moving process, is different from conventional badminton balls in moving trajectory and own rotation; and in the other aspect, in a process that the badminton ball gets into contact with a racket, an athlete can sense stress situation in a ball hitting process more clearly through the motions of theguide ball, so that the deflecting force caused by the airflow in the airflow passages after the badminton ball is hit through inward rotating and outward rotating force can be sensed.
