Puberty is a critical period for young athletes, characterized by significant physical, psychological, and social changes. During puberty, young athletes experience the adolescent growth spurt at the same time as intensified training regimens, which can affect performance, injury risk, and overall health. Systematic training can improve physiological and performance outcomes, but the increased training volume and changes to the body during adolescence can also heighten the risk of injuries. This article discusses the injury risks associated with adolescent growth and provides comprehensive recommendations to mitigate these risks. Key recommendations include limiting training hours to the athlete’s age, monitoring growth and maturation to adjust training loads and content, and incorporating and modifying consistent strength and conditioning prescriptions. In addition, optimal nutrition, sleep, and interdisciplinary planning among coaches, parents, and stakeholders should be emphasized to support young athletes’ holistic development and well-being during the adolescent growth spurt.

If you want to manage the performance of assets worth hundreds of millions of dollars, you better know what you’re doing. At the elite and professional levels of sport, strength and conditioning coaches are responsible for managing the performance of teams’ most valuable assets – The Athletes.

The National Strength and Conditioning Association (NSCA) announces today the release of the organization’s newest textbook, the NSCA’s Essentials of Sport Science. This cutting-edge publication brings together many of the world’s top experts from the sport science field to build a definitive resource for the profession.

Meet the 2026 NSCA Peer & Special Recognition Awards recipients, who will be recognized for excellence across the profession at the NSCA National Conference.

Dr. Tim Suchomel gives the annual Dr. Mike Stone Lecture at the 2021 National Conference and discusses muscular strength in detail, including its effect on performance variables, effective training progressions, and strategies for athletes through the whole training spectrum.

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.

Hybrid fitness competitions such as HYROX have rapidly gained popularity, blending aerobic endurance running with a variety of high-intensity resistance and ergometer-based stations in a globally standardized format. The sport’s unique structure, comprising eight 1-kilometer runs interspersed with diverse workload stations, presents distinct physiologic, biomechanical, and technical demands. This review synthesizes existing research on hybrid fitness events to identify the key determinants of HYROX performance, emphasizing aerobic capacity, anaerobic power, local muscular endurance, and maximal strength. The aerobic system is foundational, enabling recovery between high-intensity efforts and sustaining performance during the event’s prolonged duration. Conversely, anaerobic capacity is critical for executing the high-intensity efforts demanded by each fitness station. Local muscular endurance supports repeated submaximal contractions, while strength and power underpin performance in movements such as sled pushes and running economy. Technical proficiency and injury prevention strategies are also discussed, alongside targeted programming recommendations, including high-intensity interval training, circuit training, and blood flow restriction methods. Despite its growing popularity, limited sport-specific research exists, necessitating further investigation to refine training and performance strategies. This review provides a comprehensive framework for athletes and coaches to optimize preparation and performance in HYROX, contributing to the broader understanding of hybrid fitness competitions.
