The National Strength and Conditioning Association (NSCA) is proud to announce the recipients of the organization’s 2025 Coach of the Year Awards

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.

This brief excerpt from NSCA’s Essentials of Sport Science discusses skill-based key performance indicators (KPIs).

Key performance indicators (KPIs) are commonplace in business and sport. They offer an objective means to link data and processes with performance outcomes. Yet, their application in sports performance, particularly team sports, is not without issue. Here, we review 4 key issues relating to KPI application in team sports; lack of a universal definition, complexity of performance, drifting from on-field performance goals with off-field targets, and agency issues across different key stakeholders. With these issues relating to sports performance KPIs in mind, we propose a complementary approach to help practitioners focus on implementing the conditions that create performance environments and opportunities for success in a complex sporting environment. Ongoing process trackers (OPTs) are quantifiable measures of the execution of behaviors and processes that create the environments, cultures, and conditions for successful performance outcomes. This approach equips sports science practitioners with key questions they can ask themselves and their team when starting to select and use OPTs in their program.

The National Strength and Conditioning Association is governed by a Board of Directors that is elected by the NSCA membership. The board is comprised of eight members of the NSCA and one elected public member.

Christina Rasnake, Director of Sport Science and Analytics at the University of Delaware, talks to the NSCA Coaching and Sport Science Program Manager, Eric McMahon, about the budding future of sport science in college athletics. Topics under discussion include the staffing of sport science initiatives, effective communication across departments, and how technology and wellness surveys can support actionable change in the coaching process.
