This excerpt from Developing Power explains how to use bands for variable resistance training.

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.

The VO2max test is the most effective measurement of the body’s ability to deliver and use oxygen for producing energy that can be used by the muscles. VO2max (i.e., maximum aerobic power) simply stands for the maximal volume of oxygen that can be used.

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.

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.

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.

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 catecholamines—primarily epinephrine, but also norepinephrine and dopamine—are secreted by the adrenal medulla and are important for the acute expression of strength and power because the hormones act as central motor stimulators and peripheral vascular dilators to enhance enzyme systems and calcium release in muscle.

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.

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.
