The goal of this brief review is to describe what classifies as high-intensity interval training (HIIT) and summarize the potential benefits for various populations: athletic, general, and clinical.

Matthew Ibrahim, Co-Owner of TD Athletes Edge, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about using setbacks as a learning opportunity.

Your career can accelerate when you ask, offer, and say yes. For Morgan Smith, that approach led to a postdoctoral fellowship with the Wu Tsai Human Performance Alliance at Stanford University. Smith recalls how coaching sparked her interest in the science behind performance. Working across academic and practical settings, she encountered challenges with research feasibility firsthand. Today, she focuses on blending coaching with sport science. At Stanford, she began by building relationships and trust within the athletic department. She describes collaborating with coaches and staff to identify research interests, gaps, and low-burden contributions. Smith also highlights opportunities to support club sports, campus recreation centers, and community programs. These roles can help fund education while building your resume, network, and practical skills. She reinforces the value of education as a time to maximize experience and explore interests. Discover how to gain applied experience early, drive cross-department buy-in, and cultivate relationships that move your career forward.

Although it may be possible to increase skeletal muscle levels of carnitine by combining it with relatively large amounts of carbohydrates repeatedly throughout the day, or by taking it with choline, there is limited data that shows that carnitine is a fat-burner that results in significant reductions in fat mass.

This article provides methods used by tactical facilitators, related research articles, and professional interviews to demonstrate how physical conditioning facilitates the transition from practice to duty for service members, including law enforcement and fire and rescue personnel.

This episode of the NSCA Coaching Podcast features Nicole Fowler, the Assistant Strength and Conditioning Coach at Phillips Exeter Academy. Fowler connects with the NSCA Coaching and Sport Science Staff, Eric McMahon and Kevin Gregory, about transitioning from collegiate coaching, at Merrimack University and the University of Denver, to now working in a high school. Learn what it means to be “unembarassable” in your coaching and how that helps your strength and conditioning program. The impact of the high school strength and conditioning coach extends far beyond weight room in this episode. Tune in to learn more about programming for high school student-athletes and training insights for youth during the pre-college formative years.
