Although fatigue is commonly experienced in many highly demanding occupations (e.g., military, first responders, etc.), it is poorly defined. Fatigue can strongly affect occupational performance by negatively influencing the ability to interact with the world by altering the capacity to think, move, feel, see, and speak. The first step in fatigue risk management strategies is to establish a context. The context of this narrative review is to specifically describe and discuss the 6 overarching types of occupational fatigue: cognitive, physical, burnout, emotional, visual, and vocal fatigue, and how each affects varying occupations. Furthermore, fatigue type can be influenced by several intrinsic factors, such as sleep deprivation, circadian alignment, ultradian process, sleep homeostasis, and health factors. Similarly, extrinsic factors influence fatigue, such as workload, shift work, and environmental issues. Understanding the types and contributors to occupational fatigue may help clarify the context of occupational fatigue and serve to guide future occupational fatigue management.

This article is part of a continuing series of tactical strength and conditioning (TSAC) research reviews. It is designed to bring awareness to new research findings of relevance to tactical strength and conditioning.

This article will highlight an intervention involving mental skills training and virtual reality (VR) to address acrophobia with this population.

This article summarizes several sessions at the American College of Sports Medicine (ACSM) 62nd Annual Meeting, held in San Diego, CA, May 27–30, 2015 that examined various aspects of tactical performance.

This article discusses the impact and importance of resistance training with kids on their mental and physiological health and well-being.

This excerpt from NSCA’s Guide to Sport and Exercise Nutrition explains branched-chain amino acids

A fundamental training program at a young age gives the athlete the opportunity to develop many skills needed to succeed. The implementation of agility and coordination training can help reduce the risk of injury and elevate a young developing athlete.

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.

To address and combat neurocognitive decline in tactical personnel, this article will detail the mechanistic underpinnings of, and describe how to apply, attention regulation strategies to facilitate greater skill acquisition, retention, and performance transfer.

This article aims to provide a good understanding of sleep health and the way it affects high performance populations.
