Tom Williams’ journey to Head of Performance and Sport Science for Major League Soccer (MLS) powerhouse, the Los Angeles (LA) Galaxy, began at a crossroads: pursue traditional coaching or medical pathways. As a soccer “Swiss Army knife,” he embraced early sport science alongside coaching, building a career defined by collaboration and innovation. At the Galaxy, Williams is part of a web of support that uses rich data storytelling tailored to stakeholders and players, guiding decisions and infusing value in every encounter. This system drives their three key pillars: winning championships — including their recent record-breaking sixth MLS Cup — developing a robust academy pipeline, and leading innovation. In MLS’s “cultural melting pot,” Williams balances diverse backgrounds and short-term demands like fixture congestion while employing sustainable long-term strategies. With a unique full-time cognitive department and creative approaches like dodgeball warm-ups, he combines trust and ingenuity to elevate performance and presents a blueprint for those exploring emerging sport science.

A qualified strength and conditioning professional in the high school environment can benefit both the school and the students in a number of ways, including injury reduction, improved performance, and risk management.

The purpose of this article is to discuss the health and occupational implications of firefighters not currently meeting the National Fire Protection Association (NFPA) aerobic capacity recommendations.

The playing field has changed in collegiate athletics, but Kaz Kazadi knows the keys to longevity. Get to know the Texas Christian University (TCU) Assistant Athletic Director of Football Human Performance, renowned for his ability to inspire athletes. Follow his roots from the Democratic Republic of Congo (DR Congo) to playing for the National Football League (NFL) Los Angeles Rams — later becoming a “roaming gladiator” in the Canadian Football League (CFL) and NFL Europe to secure tenure. As a leader in the weight room, strength and conditioning was a natural transition. He recalls choosing a graduate assistantship to embody his “long money” philosophy of purpose-driven education, networking, and positivity. Kazadi compares new Name, Image, and Likeness (NIL) policies to free agency and talent acquisition versus recruiting. Additionally, he drills decision-making and delayed gratification as players transition into adulthood. He concludes with advice for creating a coaching network and career vision.
