This excerpt from Developing the Core briefly defines closed- and open-chain exercises and their respective roles in training.

This Kinetic Select from Developing the Core reviews the effects of muscle activity when performing exercises on unstable surfaces.

This excerpt from the Essentials of Strength Training and Conditioning, 4th Edition gives a quick glimpse into some of the implements used in strongman training.

This article features the recharge skate—an in-season hockey conditioning drill, designed by the authors, to maintain hockey-specific energy system fitness throughout the competitive season.

The purpose of this article is to strongly suggest and offer a pragmatic and stepwise approach that takes into account the ideas and concepts of shared decision making that allows for the “best practices,” pre-participation screenings, evaluations, and stratification flow charts for safe and effective return to play for athletes.

This Kinetic Select excerpt from the Essentials of Strength Training and Conditioning, Fourth Edition describes the results from electromyography (EMG) studies on the neural adaptations to anaerobic training.

This excerpt briefly describes key aspects of this nonessential amino acid including its effect on the body, efficacy, and adverse effects.

Potentially, an instability training program that first involves static balance and then progresses to dynamic balance activities would improve intrinsic balance. This improvement in balance would increase movement confidence, releasing the neuromuscular system from a stiffening strategy to more unimpeded motion, force, and power development.

NSCA Tactical Program Managers, Jason Soileau (Military) and Mandy Nice (Public Safety), talk to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about supporting those in the tactical professions over the course of their careers. Topics under discussion include the U.S. Army Holistic Health and Fitness (H2F) program and developing a new tactical strength and conditioning program tool kit for public safety agencies.

Get to know Army Lieutenant Colonel Nick Barringer, Program Director for the United States Army-Baylor University Master’s in Nutrition. Barringer shares how he originally planned to become a strength and conditioning coach before a nutrition course inspired him to pursue dietetics. However, it was his Certified Strength and Conditioning Specialist® (CSCS®) credential that ultimately landed him his role as the first 75th Ranger Regiment (Army Rangers) Dietitian. He recounts drawing inspiration from the Navy SEALS to start the Ranger Athlete Warrior (RAW) program and seeing the Special Operations THOR3 program follow suit — laying the groundwork for the US Army Holistic Health and Fitness (H2F) system. Barringer and McMahon discuss the synergy between strength and conditioning coaches and dietitians, as well as cultural challenges and diverse training ages in tactical settings. The pair also stress the importance of sales and building relationships before discussing basic nutrition advice and pathways into tactical and dietetics careers.
