This article is the 12th in 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.

Body composition is an important physical characteristic to consider for football players and their performance. Tyler Bosch goes over the various methods of measuring body composition, what the numbers really mean, and how they can be used to develop a player's training.

This article discusses how first responder organizations can optimize their training programs through scientific techniques, including the measurement of training load.

The purpose of this article is to address the key elements when designing a training program for firefighters, provide evidence for utilizing circuit training, and suggest recommendations on how to incorporate circuit training into the training program.

Approximately 2 million youth from 6 - 12 years of age participate in football every year. This article discusses the importance of long-term athletic development (LTAD) for youth football athletes and the significance of a player development pathway for long-term success and longevity in the sport.

When William Kraemer first entered the field, strength and conditioning was, as he puts it, “primordial.” There were few standards, limited research, and little shared understanding. As one of the most influential figures in strength and conditioning, Kraemer recounts how the profession grew from humble beginnings into a science-driven discipline. That history still holds weight for coaches today. He explains why coaches are often drawn to new ideas, but progress comes from building on proven principles. Workout logs are central to his approach, and he notes how analyzing training over time can improve decision-making. He also emphasizes alignment across the performance ladder to support innovation and athlete development. As the Senior Advisor for Sports Performance and Sports Science at The Ohio State University, he shares his perspective on where the field is headed next. Apply his wisdom to stay grounded in solid principles, evaluate training with greater precision, and better serve your athletes.

Robert Panariello, Chief Clinical Officer with Professional Physical Therapy and the Professional Athletic Performance Center, talks to the National Strength and Conditioning Association (NSCA) Head Strength and Conditioning Coach, Scott Caulfield, about education in the field, being a well-rounded coach to excel or compliment your career, and key things to remember in the strength and conditioning field.

Deloading is widespread, but its application is often inconsistent and undervalued. That gap caught Lee Bell’s attention after discovering there was no consensus definition. Bell is a Senior Lecturer at Sheffield Hallam University who focuses on the deloading, overtraining, and overreaching spectrum. He explains how overtraining and overreaching are sometimes used synonymously. That confusion is compounded further by associations with overtraining syndrome (OTS). Instead, Bell frames overreaching as a “window of opportunity” when used intentionally. For example, a planned overreach can be functional or non-functional based on recovery. Bell also examines opportunities and tradeoffs in modern periodization models. He contrasts flexible and fluid approaches with more traditional, rigid programming; each approach has implications for athlete trust and recovery. Looking ahead, Bell envisions a collaborative approach to sport science driven by coaching needs. He reflects on recent coaching survey data and the key themes that emerged for the future. Hear his perspective on next steps in velocity-based training, individualized periodization, and variability.
