This article is the 11th in 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 communities.

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.

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.

Chronic fatigue, stress, sleep deprivation, unhealthy diets, and pain can be commonplace in most departments. The tactical facilitator should try to keep their action plans simple and achievable to help prevent injuries and optimize performance.

This article aims to bring awareness to the importance of sleep and recovery for first responders, as well as providing strategies to optimize sleep specific to their occupational demands.

The purpose of this article is to discuss creatine supplementation for athletes by addressing supplementation for athletic performance, recovery, cognition, brain function, safety, contraindications, and other special considerations.

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

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 propose a training model for the aging firefighter to improve the athletic qualities of aerobic fitness and muscular strength so that they may remain healthier longer into their careers.

Annette Zapp, Lieutenant Firefighter in Chicago, talks to the Former NSCA Head Strength and Conditioning Coach, Scott Caulfield, about strength and conditioning in the firefighting niche. Topics under discussion include the perks of being a firefighter who is also a Certified Strength and Conditioning Specialist® (CSCS®) and Tactical Strength and Conditioning Facilitator® (TSAC-F®), the typical lifestyles and attitudes of firefighters in general, and common issues that they face both physically and mentally.
