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

This excerpt from NSCA’s Essentials of Personal Training discusses the importance of education on proper running surfaces, appropriate footwear, and the benefits of cross-training in addressing overuse of the knee.

Football is evolving fast, and the coaches who keep pace are the ones who control what they can and win the little details. Ted Rath, Director of Sports Performance for the New Orleans Saints, reflects on over 15 years in the National Football League (NFL). He explains how training times, availability, and sheer athleticism have shifted with the game's expansion. Rath makes the case for gaining a well-rounded experience by coaching different sports, seeking knowledge, and being patient on your path. He also shares his linear progression approach to sport science that keeps new tools actionable and avoids technology overload. With players now arriving more educated and invested in their data, creating understanding and buy-in remains essential. Rath reveals that his coaching philosophy and culture starts with “leading yourself,” emphasizing ownership and helping others. Apply his perspective to protect availability, dial in the little details, and integrate sport science with purpose.

An organized, science-based, and evidence-based periodized program that is guided by capable and competent professionals is the most efficient and effective way to accomplish the task of returning from a shoulder injury to full active duty. The concepts of periodization paired with evidence-based strength and conditioning interventions provides the framework needed for tactical facilitators to accomplish this task.

This article explores the critical role of nutrient timing in optimizing energy levels, supporting recovery, and enhancing overall physiological responses.

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.

Factors such as the types of exercises used, the number of muscle groups trained per session, the structure of the program, and the client’s training status and overall fitness level dictate training frequency.

Almost all functional movements of the trunk are combinations or variations of four basic movement patterns: trunk flexion, trunk extension, trunk rotation, and trunk lateral flexion. This article lists exercises to address each of these movement patterns.

This purpose of this article is to supply personal trainers with resistance training techniques, progressions, and cues that can assist their clients in overcoming sarcopenia and to eventually press to the overhead position pain free and with confidence.

Bone tissue is “alive” and is a dynamic tissue that can respond to resistance training. In addition to the obvious effects of resistance training on muscle mass and strength, resistance training may lead to decreased risk for osteoporosis, fractures, and falls in later life.
