This article presents information about assessing speed and agility in a controlled environment with a test that is similar to the actual demands of a specific sport.
For many athletes, being agile is the end goal of physical performance training. It represents their capacity to change velocity and direction in response to the actions of their opponent and the opportunities and constraints of their environment. The aim of this article was to describe the pitch-based development of agility, focusing on 60–1808 turns. This ensures all turns have the demand of deceleration, turning, and reacceleration, requiring both outside leg turns (608) and inside leg turns (1808). To enable the effective coaching of these, coaches must understand movement mechanics and thus the fundamental principles that underpin good technique. Within agility training, a detailed appreciation of how the center of mass and base of support interact to affect the direction of force is fundamental to this. This understanding and the ensuing technical models ensure athletes have the best chance of executing the task optimally and ensure coaches can effectively instruct athletes and adapt drills accordingly.
This excerpt from Developing Speed looks at how a fundamental understanding of the biomechanical principles that affect speed can assist coaches and athletes in developing running speed.

Athletes in field and court sports require reactive agility—they must accelerate, decelerate, and change direction in a constantly changing environment. These requirements result in technical differences between sprinting in a field or court sport and sprinting the 100-m.
Acceleration and maximum speed are terms used in speed development programs, and when developing a program, it is vital to differentiate between the two. This allows coaches to target their training to the capacity most important in their own sport.
This article discusses using the principle of specificity as an important component in tactical training programs to enhance performance, decrease injuries, and improve functional longevity of a tactical athlete.

Paul Comfort, program leader for the Master’s degree in Strength and Conditioning at the University of Salford, talks to the NSCA Coaching Program Manager, Eric McMahon, about his desire to continuously learn through practical application and research in the field. Topics under discussion include creating the post graduate program for the University of Salford, being a founding member of the United Kingdom Strength and Conditioning Association (UKSCA), and the complexities of technology in the weight room.

Sheri Walters’ journey to Director of Sports Medicine at Texas A&M University reflects a career defined by innovation, collaboration, and comprehensive integration. Walters discusses the "arms race" in collegiate athletics and how Texas A&M shatters silos through unit alignment and being intentionally present. Drawing from her EXOS experience, she highlights the impact of integrating sports medicine with strength and conditioning. Walters employs research-based cross-body training to maintain strength, prioritizing long-term rehabilitation over limb symmetry index testing. She explains how her Certified Strength and Conditioning Specialist® (CSCS®) and Certified Performance and Sport Scientist® (CPSS®) credentials enable her to elevate rehabilitation and speak the language of sport performance professionals. Walters underscores the importance of getting student-athletes back to team strength and conditioning as soon as tissues can tolerate it to promote physiological and psychological healing. She also shares how strength and conditioning coaches can optimize return to performance and reduce reinjury risk.
