High-intensity strength training paired with explosive, high-velocity movements is suggested to enhance endurance performance. It is recommended that a practical approach be taken when implementing this model of strength training, which would involve a thorough preparatory period.

The path to the top is not always linear. For Jill Costanza, it included returning to school and stops in collegiate and military performance before becoming Director of Sport Science and Assistant Strength and Conditioning Coach with the National Football League (NFL) Detroit Lions. Costanza describes today’s sport science landscape as a “Wild West,” where definitions differ by perspective. Her focus centers on assessing the athlete and program effectiveness against the demands of the game to identify holistic interventions. She outlines how intentional systems, a clear communication funnel, and data visualizations help athletes and stakeholders understand the “why,” build buy-in, and tap into competitiveness. Addressing common misconceptions, Costanza clarifies that elite athletes can still have foundational qualities that need rewiring. She emphasizes movement quality, proprioception, and breathing while adapting for individual needs and neurological fatigue. Learn how to build sport science systems, turn insights into action, and keep progressing on your professional path.

Deloading is widespread, but its application is often inconsistent and undervalued. That gap caught Lee Bell’s attention after discovering there was no consensus definition. Bell is a Senior Lecturer at Sheffield Hallam University who focuses on the deloading, overtraining, and overreaching spectrum. He explains how overtraining and overreaching are sometimes used synonymously. That confusion is compounded further by associations with overtraining syndrome (OTS). Instead, Bell frames overreaching as a “window of opportunity” when used intentionally. For example, a planned overreach can be functional or non-functional based on recovery. Bell also examines opportunities and tradeoffs in modern periodization models. He contrasts flexible and fluid approaches with more traditional, rigid programming; each approach has implications for athlete trust and recovery. Looking ahead, Bell envisions a collaborative approach to sport science driven by coaching needs. He reflects on recent coaching survey data and the key themes that emerged for the future. Hear his perspective on next steps in velocity-based training, individualized periodization, and variability.

If manipulation of the training variables is not tailored correctly to the desired adaptations and specific training goals, an athlete can experience symptoms of nonfunctional overreach. If this process continues, the athlete can develop overtraining syndrome.

What does it take to become an award-winning Director of Strength and Conditioning in the National Football League (NFL)? Justin Lovett reveals the “we over me” mentality that guides his role with the Los Angeles Rams. Lovett reflects on receiving the 2024 NSCA Professional Strength and Conditioning Coach of the Year Award after being an NSCA Member for over 20 years. He draws parallels between working with high school and NFL athletes — where the desired training responses are the same and ability levels vary — making versatility key. Lovett also stresses the importance of finding clean and effective training methods to accommodate wear and tear in football athletes. He compares the Rams’ hiring philosophy to gathering “infinity stones,” emphasizing character attributes, culture alignment, and staff chemistry. Lovett and NSCA Coaching and Sport Science Program Manager Eric McMahon discuss progressing into leadership and the rise of performance director roles, as well as how to seek out career and networking opportunities.

Lindsey Kirschman sees her non-traditional educational background as her greatest asset, not a detriment. She still considers herself a teacher — just differently — as the Director of Sports Performance for University of Utah women’s basketball. Coming from a family of educators, Kirschman initially studied forestry and range science before pursuing strength and conditioning. Kirschman explains how her teaching experience provided a firm foundation for optimizing learning and creating a positive environment. Her approach promotes skill transfer from the weight room to sport and beyond, using exercises like sled pushes as analogies for life lessons about resilience. A former track athlete, Kirschman underscores that while the finish line is the same, every athlete’s starting point is unique. Kirschman also discusses culture building through her “GOAT Award” and the challenges of transitioning from a generalist to a specialist. She encourages aspiring professionals to reframe their mindset and fully engage with their working environment.
