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.

Early sports specialization has been a controversial topic in the field of sports medicine, training, and conditioning. Recent studies report increased sports-related injuries in single-sport specialized athletes compared with multisport specialized athletes.

Physique versus Sports Nutrition: Are they Contradictory?

Physique versus Sports Nutrition: Are they Contradictory?

As the prevalence of disordered eating in sport continues to increase, sports dietitians and all medical personnel must learn to identify it properly and follow evidence-based practice, including sound judgment, when treating athletes with these issues.

Adequate nutrition generally promotes training adaptations and thus optimal performance. Adolescence is characterized by a pubescence growth spurt, increasing energy and nutrient needs. Most team sports literature focuses on male athletes, with little on adolescent female team sports. Adolescent female athletes are at an increased risk of inadequate energy, and micronutrient intakes because of the pursuit of high fitness levels, and society pressures. This may cause hormonal irregularities, delayed development, poor bone health, and increased risk of injury. This review synthesizes information on the nutritional needs of adolescent female team sport players for performance and health.

Mark Kovacs, PhD, CSCS,*D, spoke during the NSCA's 2013 Coaches Conference about the importance of balancing conditioning with strength training, and the need to approach program design in such a way that all your athletes get what they need, no matter their fitness level or sport.

Athletes in field and court sports require reactive agility—they must accelerate, decelerate, and change direction in a constantly changing environment. These requirements result in technical differences between sprinting in a field or court sport and sprinting the 100-m.

Learn how to evaluate the performance model of non-traditional, freestyle sports, and subsequently design the preparation framework that will positively influence performance. In this session from the NSCA’s 2017 National Conference, Jeremy Sheppard explains how to provide an effective training environment that is embraced by the athletes, as well as the mindset of athletes who are rule makers and rule breakers, not rule followers.

While analyzing the speed requirements of different sports may, at first, seem to be a massive challenge, asking a few key questions can make the task much simpler.
