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.

This article gives a firsthand account of working in a few of the United States Army’s earlier human performance and injury reduction programs as a strength coach and active-duty physical therapist.

The purpose of this article is to inform readers of a training tool which is both safe and effective in allowing swimmers to develop strength and power through a unique training protocol.

This TSAC Report article examines the primary risk factors contributing to shoulder pain in tactical athletes and provides evidence-based rehabilitation strategies. Visit NSCA online to learn more about exercise research for tactical athletes.

From the 2019 Tactical Annual Training, Rob Orr, co-lead of Bond University’s Tactical Research Unit, explains how the backs of tactical personnel can be compromised. He also details the systems that affect the back and how to construct programs to optimize physical conditioning and reconditioning.

From the 2021 NSCA’s Coaches Conference, Matthew Ibrahim, Co-Owner, Director of Strength and Conditioning, and Internship Coordinator at TD Athletes Edge, discusses how to help athletes develop the skills necessary to build the brakes in the athletic development process. Other topics covered include how to create a better understanding of the transfer from training in the weight room to sport performance.

Matthew Ibrahim, Co-Owner of TD Athletes Edge, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about using setbacks as a learning opportunity. Topics under discussion include creating a holistic approach to a client’s training by collaborating with other professionals, and the importance of deceleration technique and eccentrics in his programs for skill acquisition.

This article aims to discuss concurrent activation potentiation (CAP) and the proposed mechanisms underlying it, summarize the available research examining the phenomenon, and provide strategies for its implementation.

This article in NSCA Coach discusses how machine-based testing can be used to gather data and improve training. Visit NSCA online to learn more on sports science and exercise research.

Isolated muscle training methods do not necessarily transfer to better sports performance, because technique as well as strength contributes to successful performance. Resistance training for dynamic sports must involve ground-based movements that incorporate the coordinated stabilizing and dynamic functions of multiple muscles.
