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.

This excerpt from NSCA's Essentials of Tactical Strength and Conditioning aims to educate on some fundamentals of energy systems training in tactical personnel.

The path to the top is not always linear. For Jill Costanza, it included returning to school and stops in collegiate and military performance before becoming Director of Sport Science and Assistant Strength and Conditioning Coach with the National Football League (NFL) Detroit Lions. Costanza describes today’s sport science landscape as a “Wild West,” where definitions differ by perspective. Her focus centers on assessing the athlete and program effectiveness against the demands of the game to identify holistic interventions. She outlines how intentional systems, a clear communication funnel, and data visualizations help athletes and stakeholders understand the “why,” build buy-in, and tap into competitiveness. Addressing common misconceptions, Costanza clarifies that elite athletes can still have foundational qualities that need rewiring. She emphasizes movement quality, proprioception, and breathing while adapting for individual needs and neurological fatigue.
