In this session from the 2015 NSCA National Conference, Nelson Ayotte—the Strength and Conditioning Coach for the St. Louis Blues National Hockey League (NHL) team—explains how to design and implement a specific energy systems program at the elite level. Ayotte demonstrates the characteristics of each of the three energy systems and their trainability, and explores how to understand the energy demands of a sport by analysis of its characteristics, competition intensity, and duration of efforts and recovery periods.

Body composition is an important physical characteristic to consider for football players and their performance. Tyler Bosch goes over the various methods of measuring body composition, what the numbers really mean, and how they can be used to develop a player's training.

The purpose of this article is to present a sample injury prevention program with a specific emphasis on lower body posterior chain development throughout competitive and non-competitive college lacrosse seasons.
