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.

Eccentric resistance training has been shown to elicit beneficial effects on performance and injury prevention in sports because of its specific muscular and neural adaptations. Within the different methods used to generate eccentric overload, flywheel eccentric training has gained interest in recent years because of its advantages over other methods such as its portability, the ample exercise variety it allows and its accommodated resistance. Only a limited number of studies that use flywheel devices provide enough evidence to support the presence of eccentric overload. There is limited guidance on the practical implementation of flywheel eccentric training in the current literature. In this article, we provide literature to support the use of flywheel eccentric training and present practical guidelines to develop exercises that allow eccentric overload.

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

This article takes a closer look at training strength and stiffness in connective tissues.

This article outlines some very basic procedures for video analysis that strength and conditioning professionals can use to identify the physical demands of specific activities.

This video demonstrates techniques used for the four primary components of deceleration: dynamic balance, eccentric strength, power, and reactive strength.

For those dealing with clients who have back pain, this article focuses on non-specific low-back pain and potential exercise solutions for it.

The Scholastic Action Shooting Program (SASP) is a speed shooting competition designed for school-aged youth. The key to training a successful SASP competitor is to not overlook the often forgotten balance and eccentric training exercises that target key muscle groups involved in the competition. An implementation of balance and eccentric training is suggested to aid the performance of young shooters in competition.

Accentuated eccentric loading (AEL) can be combined with lower-body power-based movements to acutely enhance them; however, currently, there are limited recommendations for this training method. AEL can enhance force and power metrics during its utilization with lower-body power based exercises. When using AEL, exercises should consist of jump squats and countermovement jumps with loading methods consisting of weight releasors or dumbbell hand release. Elastic bands can be used; however, more research is needed in this area. External loads ranging from 10–30% of body mass can be used. Future research needs to investigate increased eccentric and concentric loads when using AEL with power based movements.
