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 excerpt from Developing Speed describes an agility drill that aims to develop change of direction.

This article reviews electromyography (EMG) procedures as well as provides examples of how EMG data analysis has been used in tactical populations.

Law enforcement and correctional officers have the potential to be in a physically demanding situation at any time. This article is an overview of a conditioning program that can be used in physical training for recruits in the academy.

This article is the fourth of a continuing series that examines pertinent and recent tactical strength and conditioning research reviews.

This article examines training from collegiate lacrosse programs and how this data can be used to develop data-informed recommendations and refine current approaches towards preparing military and tactical personnel for the Army Combat Fitness Test.

Decompressing after a workout, practice, or competition is a beneficial habit that can be achieved through breathing. This article provides an overview of the autonomic nervous system and guidelines for how to use breathing to calm, or balance, the brain and body.

Dr. Tim Suchomel, Assistant Professor at Carroll University and Wisconsin State Director for the NSCA, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about the emerging role of sport science in strength and conditioning. Topics under discussion include Suchomel’s growing involvement with the NSCA, as well as weightlifting derivatives and their benefits for more individualized performance adaptations.
