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.

Circuit training is quick and effective way to induce training adaptations that are similar to the demands that tactical officers face in their career. This is a basic layout of a circuit training program that can be implemented to recruits during training to prepare them for the physical demands they will face.

This excerpt from NSCA's Essentials of Tactical Strength and Conditioning aims to educate on some fundamentals of energy systems training in tactical personnel.

In the second of this two part series, this article will discuss program design with an emphasis on integrating lower limb plyometric training into soccer training to enhance power actions, as well as, consider high school athletes’ biological characteristics and long-term athletic development (LTAD).

Deloading is widespread, but its application is often inconsistent and undervalued. That gap caught Lee Bell’s attention after discovering there was no consensus definition. Bell is a Senior Lecturer at Sheffield Hallam University who focuses on the deloading, overtraining, and overreaching spectrum. He explains how overtraining and overreaching are sometimes used synonymously. That confusion is compounded further by associations with overtraining syndrome (OTS). Instead, Bell frames overreaching as a “window of opportunity” when used intentionally. For example, a planned overreach can be functional or non-functional based on recovery. Bell also examines opportunities and tradeoffs in modern periodization models. He contrasts flexible and fluid approaches with more traditional, rigid programming; each approach has implications for athlete trust and recovery. Looking ahead, Bell envisions a collaborative approach to sport science driven by coaching needs. He reflects on recent coaching survey data and the key themes that emerged for the future. Hear his perspective on next steps in velocity-based training, individualized periodization, and variability.

In this lecture from the NSCA's 2014 Coaches Conference, Dr. Bryan Mann addresses velocity-based training (VBT) in sports. Dr. Mann defines VBT as "the use of various devices that measure displacement and time" as he describes each device and its ability.

This article will detail example resistance training and aerobic conditioning sessions that could be used by a female recruit in the lead-up to their academy program.

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

Major League Assistant Strength and Conditioning Coach for the Texas Rangers, Eric McMahon, describes how he utilizes velocity-based training for professional baseball players and the benefits this technology brings to the players in this session from the NSCA’s 2019 Coaches Conference.
