This excerpt from Developing Speed demonstrates a fun drill aimed to develop the ability to make a cut step in response to a stimulus and to accelerate from this direction change.

This book excerpt explains how to perform the box step-off landing assessment, which is used to determine an athlete’s readiness before beginning a program in agility and quickness.

With the need to be ready under any circumstances from operational missions to physical training, understanding how the adrenal gland functions is important for any tactical athlete. The adrenal gland mediates performance and can have a negative effect on the body’s physiology when exhausted. It is vital to understand the interventions needed to obviate the negative effects and enhance the positive aspects of such physiological function. This session from the 2015 TSAC Annual Training sheds light on this important physiological system that impacts both physical health and functional performance.

The purpose of this article is to describe the cause of hamstring injuries in sprinters and present a biomechanical intervention, or drill, that can be used to prevent hamstring injuries while transitioning sprint athletes toward the utilization of frontside mechanics.

While there are a variety of behavior change theories and models to choose from when developing a targeted behavioral approach for a client, the transtheoretical model (TTM) provides a relatively simple and easy-to-follow model.

This article provides practical suggestions that personal trainers can use to help their clients become and stay motivated to stick with their exercise routines.

This article proposes that all resistance training exercises can be classified as either “specific” or “general.” How to classify each exercise type and the unique benefits they offer is explained.

The lack of specific training for tactical athletes during long deployments poses a significant issue. This article addresses mitigation strategies that can help them perform at their best and reduce the risk of injury.
