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.

Falls resulting from trips are a leading cause of injury and can sometimes result in death, especially in the older population. Numerous researchers have studied the biomechanical mechanisms that differentiate fallers from nonfallers and determined whether training can beneficially impact those outcomes. Exercise and task-specific interventions have demonstrated fewer falls after trips but can be costly and often require specialized equipment, making their applicability less practical. Qualified health and fitness practitioners can develop evidence-informed, exercise-based programs focusing on 3 components (balance training, task-specific training, and resistance exercise). Such programs may help to reduce fall risk in older adults based on previously documented studies identifying the biomechanical demands of a successful fall arrest after a trip perturbation. These multicomponent programs should include a safe task-specific training element that does not require specialized equipment.

Interest in investigating minimalist footwear (MF) has grown exponentially in recent years. This article systematically reviews the benefits of MF for physical fitness, biomechanical factors, and injury incidence in middle and long distance runners. A systematic review of PubMed and FECYT (Web of Sciences, CCC, DIIDW, KJD, MEDLINE, RSCI, and SCIELO) was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines before 26 April of 2022. From the 583 studies initially found, 23 were included in the qualitative synthesis. The use of MF induces improvements in running economy and stride frequency in middle and long distance races and reduces the oscillations of a runner’s center of gravity and support time. From a biomechanical viewpoint, MF enhances forefoot support and increases knee stability, leading to greater foot and ankle mobility. In addition, MF reduces impact load at the knee joint.

Various methods of eccentric training that aim to increase muscle mass or reduce ground contact time during a landing task have been extensively researched and practically examined. However, multiple methods to implement eccentric training currently exist; they differ in execution and intended training adaptions. There is a clear differentiation between an eccentric muscle action and an eccentric motion whereby a motion alludes to a downward movement of an exercise. The proposed eccentric motions are dissipating eccentrics, deceleration eccentrics, overcoming eccentrics, maximal eccentrics, and rebound eccentrics. These motions formulate into training methods and cues to allow practitioners to clearly differentiate the various eccentric training methods used in research and practice. This review proposes a new conceptual framework that clearly outlines the different forms of eccentric motions that fall into a desired eccentric training method.

Key performance indicators (KPIs) are commonplace in business and sport. They offer an objective means to link data and processes with performance outcomes. Yet, their application in sports performance, particularly team sports, is not without issue. Here, we review 4 key issues relating to KPI application in team sports; lack of a universal definition, complexity of performance, drifting from on-field performance goals with off-field targets, and agency issues across different key stakeholders. With these issues relating to sports performance KPIs in mind, we propose a complementary approach to help practitioners focus on implementing the conditions that create performance environments and opportunities for success in a complex sporting environment. Ongoing process trackers (OPTs) are quantifiable measures of the execution of behaviors and processes that create the environments, cultures, and conditions for successful performance outcomes. This approach equips sports science practitioners with key questions they can ask themselves and their team when starting to select and use OPTs in their program.

Firefighting is a profession that has the potential to be extremely demanding, both physically and mentally. More specifically, these tactical personnel must be physically fit to perform their occupational requirements, all while they are exposed to daily stressors. This is likely to include everything from physical strain and shift work to interrupted sleep and witnessing potentially traumatizing events. Failure to prepare and mitigate these occupational demands can have long-lasting implications to overall performance as well as health and wellness. Unfortunately, many of these elements often go unaddressed. As such, considerations for collaborative and overarching cross-disciplinary allied health teams should be made. Human performance optimization (HPO) is a model that has been successfully adopted by the U.S. military to enhance the overarching health, wellness, and performance of soldiers. This article proposes the utilization of a similar HPO model by providing a rationale for how it can be used to reduce premature morbidity and mortality, as well as increasing overall readiness and resilience within the firefighting profession.

In the last several decades in the United States, university athletic departments and professional sport teams began hiring sport scientists to support team operations. Many variations in sport science–related job titles and a variety of duties are apparent across the industry internationally. Therefore, the aims of this article were to (a) define sport scientist roles because they may be positioned in U.S. sport organizations, (b) demonstrate potential levels of application, (c) demonstrate how a sport science program helps establish a standard of care for the athlete, and (d) highlight overseas practices that establish professional competency for those in sport scientist roles. This discussion may be used to optimize organizational structures, enhance organizational dynamics within sport organizations, leagues, and systems, and used to develop, refine, or support certification and training programs in the United States. In addition to the discussion in this article, several job descriptions are provided as Supplemental Digital Content, http://links.lww. com/SCJ/A347. These resources may help decision makers construct job descriptions for their organizations.
