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.
As rotation, power, and rotational power are all common pieces of everyday life, it is important to train for efficiency in the movements. This article addresses the specific approaches rotational training can have in an individual’s strength program to address core integrity, synergistic muscular systems, and overall athletic capabilities as it relates to aging.

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.
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.
Scientific research has identified lactate threshold (LT) and maximal exercise performance as being very important contributors to endurance performance. A well-designed endurance training program can lead to improvement in both LT and maximal exercise performance within a single season and from season to season.
This session from the 2015 NSCA Coaches Conference is designed for the strength and conditioning coach who deals with a wide variety of sports. Scott Charland highlights how the needs of athletes in different sports are similar and shows how it is possible to operate an effective, consistent, and comprehensive strength and conditioning program with minimal staff.
