This article explains how training age, training frequency, limb length, height, and relative strength relate to concentric barbell velocities at varying loads.

This infographic briefly reviews the differences in sprint velocity and technique, including stride length and hip, knee, and ankle flexion during a 20-meter resisted sprint.

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.

This article discusses the importance of upper body power training for protective security personnel and its potential for an occupational performance marker.

“The goal of what we’re trying to do is make a difference in someone’s life,” says Gary Schofield in this session from the 2015 NSCA National Conference. Coach Schofield explains areas where you can make a difference for your athletes, including movement efficiency, recovery and regeneration, autoregulation, velocity-based training, and conditioning with purpose.

This article discusses the effects of instability on force and velocity throughout the body.

This excerpt from the NSCA’s Essentials of Sport Science, discusses some of the benefits and validity of Global Positioning Systems (GPS) data.

The purpose of this article is to justify the importance and advantage to properly incorporate upper body power (UBP) training in Mixed Martial Arts (MMA) athletes.

This article seeks to provide some insight to optimal biomechanics in running technique and why normal gravitational techniques may not suit tactical athletes while load-bearing.

Learn practical programming ideas to implement in youth speed training programs. In this session from the NSCA’s 2017 National Conference, Lance Walker explains how to leverage the differences between starting, acceleration, and maximum velocity dynamics (movement preparation) and plyometrics. Learn about the most common errors made by young athletes when training linear speed with practical tools, teachings, and contextual cues.
