The purpose of this article is to examine components that affect speed to determine the degree that speed is governed by skill versus genetic factors.

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.

How does a small-town boy from Mid Wales become the next NSCA President? Follow Ian Jeffreys’ inspiring journey, beginning with his introduction to the NSCA in 1989 as a professional rugby player hungry for knowledge to perform better. Listen as he recounts the thrill of his first conference and why NSCA events are so much more valuable than just what is presented on the main stage. Then, dive into Ian’s career-defining contributions to speed and agility, sparked by his reverse-engineering approach that leverages movement patterns and strong positioning to elevate game speed. Reflect on decades of evolution in our profession, including increased career paths plus the rise of technology and AI — and why they can never replace the true human heart of coaching. Lastly, learn Ian’s vision for the NSCA’s future, which involves both listening and leading to maintain the NSCA’s position as the worldwide authority in strength and conditioning.

Some research has found that static stretching can have detrimental effects on subsequent performance. This is not to say that static stretching should be eliminated from an athlete’s program, but it should be sensibly incorporated into the daily training regimen since chronic stretching can enhance the range of motion around a joint and potentially improve strength and power performance.
