test index also increased significantly,indicating that through sports dance training for sports dance professional female college students cardiopulmonary function has improved significantly improved.3.Flexibility,through the data processing results of sports dance professional female college students seat flexion,posterior flexure bridge,cross fork,left vertical fork and right vertical
