This warning refers to the fact that it is an assembly or collection of several themes resulting from the work of a number of specialists in the teaching of swimming, and is marked by the author's intention to cite references that will enable the reader to be referred to the primary source and author of the text, so that it is not misinterpreted.This training manual is aimed at physical activity and sports professionals. To make it easier to understand, we have written a general section for each chapter. This book has not been produced for commercial purposes, but to help teachers and coaches responsible for promoting swimming. Its aim is far more modest: to make non-specialists aware, in a pedagogical way, of the main teaching and training methods for a group of beginner swimmers. It does not aim to cover and analyze, in an exhaustive way, all the characteristics and particularities of teaching this sport.
