Racquetball consists of various movements and has different training styles and techniques that target particular skills that can affect an aging player’s performance. The drills in this article are designed to strengthen and coordinate the lower extremity muscle groups for the aging racquetball player.

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 considers some of the main differences between the training of Olympic weightlifters and the use of Olympic weightlifting exercises in strength training for sport.

This book excerpt explains how to perform the box step-off landing assessment, which is used to determine an athlete’s readiness before beginning a program in agility and quickness.

This article discusses baseball-specific strength and conditioning techniques, focusing on lower extremity training and improving shoulder mechanics.

The purpose of this article is to emphasize the critical need for a nutrition strategy that aligns with the specific demands inherent in the sport of soccer.

This article will examine the physical demands of soccer players and discuss why repeated sprint ability (RSA) is considered highly important in the performance of these athletes.

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.
