Knowledge of metabolic rate can help athletes as well as health-conscious people improve their exercise performance or obtain the fat-to-lean-mass ratio optimal for their personal situations. Two examples of how this works follow.

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.

The purpose of this article is to discuss creatine supplementation for athletes by addressing supplementation for athletic performance, recovery, cognition, brain function, safety, contraindications, and other special considerations.

This article provides a discussion around the evidence on creatine timing and supplementation.

Although it may be possible to increase skeletal muscle levels of carnitine by combining it with relatively large amounts of carbohydrates repeatedly throughout the day, or by taking it with choline, there is limited data that shows that carnitine is a fat-burner that results in significant reductions in fat mass.

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.

Various methods of eccentric training that aim to increase muscle mass or reduce ground contact time during a landing task have been extensively researched and practically examined. However, multiple methods to implement eccentric training currently exist; they differ in execution and intended training adaptions. There is a clear differentiation between an eccentric muscle action and an eccentric motion whereby a motion alludes to a downward movement of an exercise. The proposed eccentric motions are dissipating eccentrics, deceleration eccentrics, overcoming eccentrics, maximal eccentrics, and rebound eccentrics. These motions formulate into training methods and cues to allow practitioners to clearly differentiate the various eccentric training methods used in research and practice. This review proposes a new conceptual framework that clearly outlines the different forms of eccentric motions that fall into a desired eccentric training method.
