This book systematically summarizes the accuracy, precision, and repeatability levels of field-based tests applied in soccer. It considers such details as the effectiveness of tests for different age categories and sexes. In this book, the readers will be able to check all the field-based tests conceived for fitness assessment in soccer through a large systematic review made to the literature. In addition a brief characterization of each test and presentation of the concurrent validity and repeatability levels for each test will be provided. Finally, the book contains a general discussion of the implications of the tests for different methodological approaches to training. It will be use to sports scientists and practitioners.

The aim of this reprint is to provide a collection of relevant recent research in the field of soft computing, involving works on different methodologies, techniques and algorithms in soft computing, machine learning, computational intelligence, and optimization. This reprint is addressed to scientists and engineers, offering open access to a variety of innovative ideas and developments, which may further motivate new research endeavors and developments in related areas.
