Some research has found that static stretching can have detrimental effects on subsequent performance.

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.
