High Intensity Training - Expanding the Limits of Performance (Key Concepts Book 4)


This book was written by Coach Charlie Francis in 2008 to bring together many of the key training concepts of sprint training into one book. In High Intensity Training – Expanding the Limits of Performance, Coach Francis explains how every person has an absolute limit of muscular output, as well as a level of useable performance of that output. He highlights how it is impossible to reach the absolute limit of output as humans have a biological safeguard that prevents them from overloading their muscular system. Coach Francis arms the reader with the knowledge of how to extend these limits and how the sprinter's useable performance can become a much larger percentage of their absolute limit compared to an untrained sprinter. By reading High Intensity Training you will increase your knowledge on how to design your training to incorporate these concepts and gain the advantages understood by few coaches and athletes.

Coach Francis teaches how the effective improvement of useable performance, can result from a successful training program. Furthermore, this book continues to build on the role Central Nervous System (CNS) fatigue plays in the training regimen. This book helps explain how an athlete begins to feel CNS fatigue as he nears the limits of his useable performance and how having a greater useable performance is of benefit in training and in competition. In training, the athlete will be able to perform at a greater intensity and over a prolonged period of time. To understand more about this idea, take a look at more of Coach Francis’s literature with attention to understanding what is ‘speed reserve’.

As with the other books written by Coach Charlie Francis, High Intensity Training was written regarding how he trained track athletes. Over time, Francis applied the same training concepts to professional Hockey, Football, Tennis, Soccer and Basketball. Whatever your sport, understanding the implications of High Intensity Training will change the way you currently think about your training regimen.

This book brings together similar training ideas, which were brought to life in the other books in this series. To learn the specifics of the other books in the Charlie Francis “Key Concepts” series, please read "The Structure of Training for Speed",

Further information can also be found in the books Charlie Francis Training System and in more of a background read, Speed Trap. Many of the Key Concepts are highlighted in the video training series calledGPP Essentials" and "Inside the SPP" which are available at www.charliefrancis.com.

High Intensity Training is a must read for training for all sports.
