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.

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.

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.

Consumption of dietary protein by athletes is a common intervention to maximize gains in muscle and strength, and to improve body composition. The purpose of this article is to analyze the current research on the optimal amount of dietary protein for resistance training athletes.
