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.

Joe Kenn, MA, CSCS,*D, RSCC, spoke at the NSCA's National Conference about managing fatigue in players.

The ability to manage the adaptive response, handle accumulated fatigue, and capitalize on the aftereffects established from training is central to the training process.

This article provides some practical applications to minimize the negative effects associated with a long intensive ice hockey season on ice hockey athletes.

The purpose of this article is to review the related literature that has explored the influence of resistance training programs on the onset of fatigue and muscular power as it relates to non-contact high-intensity intermittent sports, in order to provide suggestions for creating same-day training programs.

The purpose of this article is to examine components that affect speed to determine the degree that speed is governed by skill versus genetic factors.

This article will review the latest evidence regarding optimal rest intervals, and the science behind them.

This article aims to help personal trainers understand the unique symptoms accompanying multiple sclerosis, how exercise recommendations change based on disease progression, and which techniques to best program for your client.

Learn how to identify the risks to an athlete’s health and safety associated with overtraining, as well as how to help the athlete to return to normal when they have reached overtraining/fatigue.
