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.

Gavin Pratt, Senior Director of Strength and Conditioning at the Ultimate Fighting Championship (UFC) Performance Institute, shares insights from his international career. Pratt reflects on preparing athletes for the Chinese National Games and managing strength and conditioning at the world’s first MMA academy in Shanghai. Applying a systems-based approach, he tackles MMA’s unique challenges — including unpredictable training schedules, diverse personalities and backgrounds, session intensity, and load management. Driven by passion rather than prestige, Pratt emphasizes he’s never been a "tracksuit hunter" — someone motivated primarily by titles or status. He highlights MMA’s innovation potential, especially when using individualized technology based on athletes' force or velocity deficiencies. Pratt contrasts the United States’ expertise in speed, agility, and change of direction with Australia’s early adoption of sports science. He also provides valuable interview advice to help coaches communicate effectively under pressure. Discover practical strategies to elevate your coaching impact.
