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.

From tactical strength and conditioning to developing the skills to train a specialized group of football kickers, Catherine Wallace shares how growing up in a military family inspired her into coaching. In this episode, Wallace connects with NSCA Coaching and Sport Science Program Manager, Eric McMahon, on how to pursue a tactical coaching career in different branches of the military and public safety. She discusses how earning the Tactical Strength and Conditioning Facilitator® (TSAC-F®) certification led her to pursue the Certified Strength and Conditioning Specialist® (CSCS®), and more ways that involvement with the NSCA has positioned her for career growth. There is also a discussion about “holistic programs” within strength and conditioning, an area that has been popularized, but is perhaps still misunderstood. Listen and learn about the rapidly growing tactical strength and conditioning area of the field, and the mindset needed to thrive as an impactful coach.
