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.

She emphasizes movement quality, proprioception, and breathing while adapting for individual needs and neurological fatigue.
