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 article addresses the implications and clinical applications of eccentric training. It also provides general exercise guidelines and future directions of eccentric training.

This excerpt from Developing Power discusses implementing plyometric training in a program to develop lower body power.

Learn about the hip rotators as they relate to performance training. In this session from the NSCA’s 2016 National Conference, Michael Griffith explains the limitations of the hip external rotators and how this can impede performance and lead to injury. This session will also provide eccentric drills and exercises for the hip rotators.

Dietmar Schmidtbleicher, Head and Chair for Sport Sciences at the Institute of Sport Sciences at the Goethe University Frankfurt/Main in Frankfurt, Germany—and one of the world’s leading experts on strength and power training—explains the influencing factors of force production in eccentric muscle actions. Schmidtbleicher made a rare appearance in the United States at the NSCA’s 2015 National Conference.

Matthew Ibrahim, Co-Owner of TD Athletes Edge, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about using setbacks as a learning opportunity. Topics under discussion include creating a holistic approach to a client’s training by collaborating with other professionals, and the importance of deceleration technique and eccentrics in his programs for skill acquisition.

This article provides a brief overview of literature where regional hypertrophy was reported. It also discusses the basic science and application of regional hypertrophy training.

Musculoskeletal injuries are the primary source of disability in the United States military. With the integration of movement screens and the implementation of tactical strength and conditioning facilitators there can be success in reducing the amount of musculoskeletal injuries in the tactical populations.

Kelly Dormandy, Assistant Athletics Director for Sports Performance at Loyola Marymount University and Head Strength Coach for the Los Angeles Sparks Women’s National Basketball Association (WNBA) team, talks to the NSCA Coaching Program Manager, Eric McMahon, about championship culture.
