From the Essentials of Strength Training and Conditioning, this book excerpt explains the various stages of tissue healing in the rehabilitation process.

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.

This excerpt from NSCA’s Essentials of Sport Science briefly explains workload and injury risk factors.

Mary Kate Feit, Assistant Professor and Associate Director of Strength and Conditioning at Springfield College, and Adam Feit, Coordinator of Physical and Mental Performance at Springfield College and Assistant Director of Performance Nutrition at Precision Nutrition, talk to the NSCA Coaching Program Manager, Eric McMahon, about being a married couple in the world of strength and conditioning. Topics under discussion include the unique positions they hold at Springfield College, how becoming parents has changed their perspective on coaching, and why diversity is so important for the future of the field.

This excerpt from Developing Speed discusses the various start patterns that exist and how to include them in a speed development program.

This excerpt breaks down the optimal positions of the body during acceleration and deceleration.

This book excerpt provides examples of quickness drills that may improve the ability to identify a specific stimulus and to respond quickly and appropriately.

Isolated muscle training methods do not necessarily transfer to better sports performance, because technique as well as strength contributes to successful performance. Resistance training for dynamic sports must involve ground-based movements that incorporate the coordinated stabilizing and dynamic functions of multiple muscles.

Two factors that determine running speed are stride cadence and stride length. Because athletes propel themselves forward only when their foot is in contact with the ground, the stance phase of the running stride should be the focus of speed enhancement programs.

Line drills can be an excellent way for athletes to improve their footwork, speed, and coordination. This article contains examples of several easy-to-implement line drills.
