This article outlines a potential learning course intended for students in undergraduate criminal justice and homeland security majors to improve their physical health literacy and health-related behaviors.

The third and final article in this series will introduce the practical and technical elements of heart rate variability (HRV) monitoring in greater depth and detail.

The research reviewed in this article provides a baseline snapshot of clinically-relevant tools to screen, diagnose, and provide treatment that can improve behavior surrounding sleep, as well as quantity and quality of sleep in occupational firefighters.

This book excerpt reviews the psychological principal of the self-determination theory (SDT) and its role in motivation and how this can be used in a tactical setting.

Tactical jobs are fast-paced, physically and psychologically intense, and failure can have tragic consequences, making it vital to train tactical athletes to perform better under stress.

Determining VO2max can be useful in all areas of health, from potential diagnosis of heart disease in the elderly to measuring peak performance in elite athletes. This article will discuss the physiological limiting factors of VO2max and the role each plays in cardiovascular improvement.

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.

Flexibility training is important because of the role that flexibility plays in improving movement performance and reducing the opportunity for injury.

High chronic workloads have been shown to be associated with a reduced risk of non-contact, soft tissue injuries, while large spikes in acute training loads have been associated with an increased risk of these types of injury. Analyzing the acute:chronic workload ratio allows a coach to optimize training for the athlete and to continue in advancing fitness goals without overtraining.

Chris Morris, Director or Performance Science at the University of Kentucky, talks to the NSCA Coaching Program Manager, Eric McMahon, about the importance of capturing athlete readiness through data and technology. Topics under discussion include Dr. Morris’s time as a University of Kentucky football player turned PhD student, how sports science is critical to understanding athlete’s capacities on a much deeper view, and developing interpersonal relationships with athletes to create trust and buy-in.
