Mark Stephenson explains the systems of stress response for tactical personnel and the cognitive influence on decision-making and reaction time.

Bridge the Gap Lecture: Understanding Energy System Development in Hockey

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.

Learn about common misconceptions about shoulder function and the process for improving shoulder mobility and stability. In this session from the NSCA’s 2017 TSAC Annual Training, Lee Burton—one of the founders of Functional Movement Systems (FMS)—provides easy-to-prescribe screens and exercise progressions to improve and maintain shoulder function.

In this session from the 2017 Coaches Conference, Joe Eisenmann explains the three major energy systems in the human body, identifies appropriate tests of physical work capacity, and explains how to design programs that maximize energy production and fatigue resistance in sports.

The catecholamines—primarily epinephrine, but also norepinephrine and dopamine—are secreted by the adrenal medulla and are important for the acute expression of strength and power because the hormones act as central motor stimulators and peripheral vascular dilators to enhance enzyme systems and calcium release in muscle.
