Training Periodization for maximizing soccer performance analyzes the training sequence that can be followed by a club targeting to improve the performance of the players. It is worth noting that the presented periodized training plan was successfully applied to the Greek Superleague club PAS Giannina FC during the 2012-2013 season. At the time the club was not allowed to buy players due to debts and despite having young players with minimal Superleague experience, achieved European qualification which was the biggest surprise of the last few years in Greek football. The book presents tools such as complete training plans, tables, and images regarding the design of the three main characteristics of physical fitness: endurance, strength, and speed. By further applying the proposed periodized plan on technical, tactical and mental/cognitive abilities we succeed improvement of the players' physical abilities as well as maximization of their soccer performance. The proposed training plans are presented in a simple and straight-forward manner, thus the model is applicable to soccer clubs irrespective of their level of participation. Special thanks to Dr. Konstantinos Patras MD, Ph.D. for his assistance in the practical application of the training plan as well as his contribution as a scientific advisor during the writing of the book.
