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.

A substantial body of literature has focused on weightlifting derivative lifts, primarily emphasizing the second pull phase because of its greater expression of force, velocity, and power output. The biomechanical resemblance of this phase to various athletic movements underscores the relevance of these derivatives in physical preparation across multiple sports. However, although the findings of these studies greatly enhance our understanding of their effectiveness in enhancing neuromuscular qualities, there remains a noticeable gap in the literature regarding the importance of the first pull phase, specifically within the sport of weightlifting. The aim of this review was to elucidate the relative importance of the first pull phase in snatch and clean & jerk performance and to explore the selection of specific pull derivative exercises that target the strength development of this phase of the lifts.

This book excerpt from Developing Agility and Quickness describes the windows of opportunity in youth athletes to time progressions in speed and agility training with their biological and chronological development.

When integrating resistance training, endurance athletes must ensure that the sessions or workouts are sequenced in the context of the overall workload. Giving careful thought to these factors when designing the training plan will increase the chances of success.

The constant presence of technology can train the mind to be in a constant state of reactivity and unease. Personal trainers can help their clients improve performance by teaching them how to focus.

This article from Developing Agility briefly discusses the importance of age-appropriate speed and agility drills.

After 27 years as Editor in Chief of the Strength and Conditioning Journal (SCJ), Dr. Jeff Chandler, EdD, FNSCA, will step away from his role in April 2025.

The National Strength and Conditioning Association (NSCA) Foundation is proud to announce the recipients of its 2025 Research, Coaching Advancement, and Equipment Grants.

Abstract submissions are open yearly from November to March (exact dates change annually). See the Abstract Submission and Presentation Guidelines for more information (below). Research abstract presentations are an opportunity to present current research findings to researchers and strength and conditioning professionals at the NSCA National Conference.

A fundamental training program at a young age gives the athlete the opportunity to develop many skills needed to succeed. The implementation of agility and coordination training can help reduce the risk of injury and elevate a young developing athlete.
