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.

Supplements that claim to boost nitric oxide have not been proven to be all that effective since the actual conversion in the blood cell is rather complicated and requires oxygen, which is usually in short supply during exercise or at high altitude. So how does an athlete boost their nitric oxide production?

Fitness testing uses a battery of protocols recognized by the scientific community as both reliable and valid, and it measures important fitness constructs such as aerobic endurance, muscular strength, muscular endurance, power, agility, flexibility, and balance.
