This infographic discusses how testing for the change of direction deficit may be a more specific measure of change of direction ability in athletes.

Before implementing an agility training program, baseline measures of change of direction ability should be assessed. This article presents norms for three tests that can be used to assess change of direction ability.

This excerpt from Developing Speed discusses the various start patterns that exist and how to include them in a speed development program.

In this Bridge the Gap Lecture from the 2019 National Conference, Head Strength and Conditioning Coach for the University of Oregon, Jimmy Radcliffe, discusses the specifics of deceleration, change of direction, and reacceleration through ground negotiation, postural control, and specific running mechanics.

This infographic briefly explains the effects of horizontal jump training, vertical jump training, maximal strength training, and explosive strength training on change-of-direction ability in junior team sport athletes.

Deceleration in court and field sports, such as football and soccer, is an important component of speed and agility. This book excerpt looks at how to train for effective deceleration.

Traditional lower-body resistance exercise alone may not be an optimal means of developing agility. Further, the effectiveness of straight-sprint training on agility performance has not been well established. In contrast, jump training, including loaded jump squats and horizontal and lateral jumps, holds promise.

For many athletes, being agile is the end goal of physical performance training. It represents their capacity to change velocity and direction in response to the actions of their opponent and the opportunities and constraints of their environment. The aim of this article was to describe the pitch-based development of agility, focusing on 60–1808 turns. This ensures all turns have the demand of deceleration, turning, and reacceleration, requiring both outside leg turns (608) and inside leg turns (1808). To enable the effective coaching of these, coaches must understand movement mechanics and thus the fundamental principles that underpin good technique. Within agility training, a detailed appreciation of how the center of mass and base of support interact to affect the direction of force is fundamental to this. This understanding and the ensuing technical models ensure athletes have the best chance of executing the task optimally and ensure coaches can effectively instruct athletes and adapt drills accordingly.

This infographic highlights an investigation into the relationship between joint-based biomechanical variables in cutting and performance outcome during change-of-direction.

The purpose of this article is to present normative data that has been previously collected for the 75PR, use the data to create informed training practices, and support the need for further research of this particular topic in law enforcement.
