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.

This book excerpt from Developing Agility and Quickness describes the windows of opportunity in youth athletes to time progressions in speed and agility training with their biological and chronological development.

This article from TSAC 76, describes first responder wellness and the effects of PPE on occupational performance. Visit NSCA online to learn about exercise science and tactical fitness.

This excerpt explains the importance of optimal nutritional strategies in conjunction with good sleep hygiene and how that can help mitigate damaging effects of deployment and shift work on performance.

The purpose of this article is to identify considerations that are to be taken into account when designing and implementing an annual training program for firefighters, as well as to discuss strategies for implementation.

Bone tissue is “alive” and is a dynamic tissue that can respond to resistance training. In addition to the obvious effects of resistance training on muscle mass and strength, resistance training may lead to decreased risk for osteoporosis, fractures, and falls in later life.
