In order to improve sports performance, physical preparation consists of a complex process whose objectives are to improve the functional capacities of the organism and to acquire the technical, tactical and psychological skills necessary for competition. The goal of physical preparation in many sports is to increase the ability to sustain speed or develop the highest power for a given distance or time. The action of training involves the repetition of exercises to automate the execution of motor skills and abilities and to develop the metabolic functions specific to performance. The objective of this book is to present the modern philosophy and the methodological and theoretical principles underlying the programming of physical preparation. This involves defining the different workloads, depending on the intensity, volume and frequency of the exercises, as well as their distribution and interactions. This book is intended for coaches, physical trainers, students of sports science, and all those interested in sports training.
