It is important for coaches to understand the relationship between commonly measured variables (e.g., displacement, velocity, and force) and their relationship to the derived variable of power.

Considering that the term "power" typically evokes the perception of high-speed movement, many people are inclined to take the tenets of specificity to literally mean “train fast, be fast.” However, to create the most strategic methods of training and adaptation, it is vital to compartmentalize power into the primary testable and trainable elements.

The purpose of this article is to provide the strength and conditioning coach with a template on how to integrate the clean and power clean into athletic training programs.

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 discusses the variability in physical testing outcomes for law enforcement recruits based on the ambient temperatures and relative humidity present on test day.

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.

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.

The purpose of this article is to provide an introduction to contrast training, including how it is defined, what variables are utilized, and examples of how to use it in training.

This article seeks to provide insight on a training method based around prescribing small amounts of training to achieve a large amount of physical improvements.

The goal of this article is to define some of the basic physiological responses to acute and chronic altitude exposure and to provide some evidence-based, practical guidelines when approaching training and racing at higher altitudes.
