Jill Costanza | Exploring the “Wild West” of Sport Science

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.

“For me personally, my philosophy is educating the athlete and giving them the why. It's their body. It's their processes that they're having to go through. So we can get buy in from the athlete, and they understand, even when they're away from us, how to take care of themselves, how to lead a healthy lifestyle, that buy in from them where they care and they're asking questions, it definitely makes the process much smoother, and they become proactive.” 12:00

“There are certain qualities that still need to be built that can sometimes be overlooked at this level because you just assume, well, they're the best of the best. They're the elite. But sometimes, we really have to regress and go back to basic motor learning, motor control, and reingrain and rewire some of these foundational movement patterns.” 14:30

“I connected with myself. I think that was probably the biggest lesson. I began to learn who I am and really formed a comfortable relationship with myself and trust in myself. I was guided by my intuition. I didn't chase after opportunities. I just focused on what I needed to do to continue to grow as a person, as a coach, and just trusted that the right people would come into my path at the right time with the right opportunity.” 22:30
