To meet the need of teaching swimming in deep pool, the study designed a set of teaching method, by which beginners cou1d learn breast stroke and swim up to 5O meters in deep water. The newly designed method put emphasis on intensified technical drill on land and aJso included simplified procedure of getting familar with the characteristics of water, improved sequence of coordination, use of floats as aids, and adoptation of collective teaching form. The method has been proved to be safe, more effective with less teaching hours and uniform progreess, and consistent to the mental and physiological characteristics of beginners.
