Regarded as a sport science advocate in Major League Soccer (MLS), follow David Tenney’s journey from sport coach to High Performance Director at Austin Football Club (FC). Tenney and NSCA Coaching and Sport Science Program Manager Eric McMahon begin by discussing increases in MLS staff and embracing the overlap between coaching and performance science staff. Tenney reflects on how experienced coaches often evolve toward mentorship, finding balance between “leader” and “practitioner.” The pair examine the new MLS-mandated performance scientist position, which requires the Certified Performance and Sport Scientist® (CPSS®) credential. Created to standardize the role and responsibilities, MLS performance scientists leverage data from GPS and force plates into effective and ethical takeaways. As President of the emerging Professional Soccer Performance Association (PSPA), Tenney shares his goals to create a network, gain representation, and increase credibility. Tenney and McMahon also explore the robust MLS developmental pipeline, interviewing strategy, and early career advice.

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.
