This excerpt from Strength Training, Second Edition briefly details hormones and their role in the human body.

This article is part of a continuing series of tactical strength and conditioning (TSAC) research reviews. It is designed to bring awareness to new research findings of relevance to tactical strength and conditioning communities.

Although most resources on program design review the foundational scientific principles of training, they often fail to provide practical strategies that strength and conditioning professionals need in order to apply these principles successfully. To help bridge the gap between science and application, this article provides a simple and practical, step-by-step system for applying the scientific principles of training into the program design process.

The purpose of this article is to discuss the various types of low-impact activities and their associated cardiovascular and musculoskeletal benefits.

This article briefly explains different squat variations, as well as how they differ from a physics and biomechanics standpoint.

The effects of alcohol on athletic performance vary depending on quantity, demographics, and type of exercise, making it difficult to determine specific recommendations. From an athletic performance standpoint, the acute use of alcohol can influence motor skills, hydration status, aerobic performance, as well as aspects of the recovery process.

This article provides methods used by tactical facilitators, related research articles, and professional interviews to demonstrate how physical conditioning facilitates the transition from practice to duty for service members, including law enforcement and fire and rescue personnel.

This article discusses the ratings of perceived exertion (RPE) scales and how to educate older clients to utilize them, as well as how to monitor and safely progress their training intensity.

This article looks to explain why law enforcement recruits have higher incidences of lower extremity bone stress responses and stress fractures. It also explores injury mitigation pathways to increase the graduation rates among law enforcement academies.

Dr. Tim Suchomel, Assistant Professor at Carroll University and Wisconsin State Director for the NSCA, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about the emerging role of sport science in strength and conditioning. Topics under discussion include Suchomel’s growing involvement with the NSCA, as well as weightlifting derivatives and their benefits for more individualized performance adaptations.
