Acceleration is the rate of change in velocity, so this phase of sprinting is critical for changing directions as rapidly and efficiently as possible. Optimal technique for linear sprinting in the acceleration phase involves four factors that maximize stride length and frequency.

This article highlights the scientific evidence on exercises like the seated leg extension, leg curl, and adduction machines to highlight their potential benefits on enhanced performance and potentially reducing injury risk.

The purpose of this article is to provide personal trainers with a review of common muscle extensibility tests of the lower extremity.

This excerpt from Developing Speed aims to develop athletes’ ability to accelerate quickly through stride modification.

Olympic-style lifting, functional training, powerlifting, and bodybuilding should all be considered when designing a program to improve general health, fitness, and functional capacity.

Deceleration in court and field sports, such as football and soccer, is an important component of speed and agility. This book excerpt looks at how to train for effective deceleration.

The NFL Combine is a week-long evaluation process that allows NFL scouts, coaches, general managers, and owners to get an up-close and personal evaluation of the talent that comprises the given year’s draft class. This is a day-by-day program outline to maximize results and effort for the NFL combine.

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.
