EISHOCKEY PERFORMANCE is a collaboration of Gerrit Keferstein & the German Icehockey Federation. On over 350 pages Gerrit Keferstein and his team drew from their experience working with many professional teams (including Kölner Haie and Grizzlies Wolfsburg), individual athletes (including Leon Draisaitl) and the German National Team, and covered all aspects of physical preparation for Icehockey from lab diagnostics, performance profiling, regeneration, nutrition to endurance/power optimisation & planning of the training process. The book is a wealth of practical knowledge for Coaches and Athletes from all sports, not only Icehockey.

“Gerrit hat es geschafft in einem kurzweiligen Buch die Grundlagen der Schlafphysiologie sowie die daraus hervorgehenden praktischen Maßnahmen zur Verbesserung des Schlafs auf spannende Art und Weise zu vermitteln. Selten hat mich ein Fachbuch so gefesselt! Vor allem in meiner Arbeit mit Sportlern hats mir einen signifikanten Mehrwert gebracht!”

One of the brightest professionals I have ever worked with, and one of my favourite people to be around!
