Learn about the anthropometric, kinematic, kinetic, and asymmetric variables that contribute to sprint performance, as well as how a coach can design effective speed development programs for male youth athletes.

In order to ensure consistent and accurate results, coaches must take certain steps to ensure proper data collection. It is also important to establish sound protocols prior to testing.

This article describes two different methods for testing core muscle power. Both of the described methods utilize medicine ball throws.

Learn about Loren Landow’s philosophy-based system of multidirectional training and explore how to best integrate multidirectional training to straight-line speed performance through a full progression of bilateral and unilateral exercises. In this session from the NSCA’s 2017 National Conference, Landow addresses the factors that influence agility with special attention to the feet and hips

This infographic briefly explains the effects of horizontal jump training, vertical jump training, maximal strength training, and explosive strength training on change-of-direction ability in junior team sport athletes.

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.

This excerpt explains the role that lactate plays in exercise metabolism and how that information is useful for athletes to predict things like pacing, fitness, and efficacy of training programs.

This article seeks to provide insight on a training method based around prescribing small amounts of training to achieve a large amount of physical improvements.

This excerpt from the NSCA’s Essentials of Sport Science, discusses some of the benefits and validity of Global Positioning Systems (GPS) data.

The purpose of this article is to describe the cause of hamstring injuries in sprinters and present a biomechanical intervention, or drill, that can be used to prevent hamstring injuries while transitioning sprint athletes toward the utilization of frontside mechanics.
