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.

Discovery Canyon High School’s Sam Melendrez explains how experts in his profession are having a profound impact on youth in sports.

Exercise is an underutilized therapy for the treatment of cognitive diseases such as Alzheimer’s disease and depression. While exercise shows more promise for the prevention, rather than the treatment, of Alzheimer’s disease, exercise therapy compares favorably to the most common treatments of depression (psychotherapy and antidepressants).

This article serves to educate strength and conditioning coaches on the influence exercise can have on the various hormonal pathways that are impacted by polycystic ovarian syndrome (PCOS), including insulin resistance, cortisol, testosterone, follicle-stimulating, and luteinizing hormones.

This article is part of a continuing series of tactical strength and conditioning (TSAC) research reviews. It is designed to bring awareness to new research findings of relevance to tactical strength and conditioning communities.

Athletes in field and court sports require reactive agility—they must accelerate, decelerate, and change direction in a constantly changing environment. These requirements result in technical differences between sprinting in a field or court sport and sprinting the 100-m.

This article will explain the interference effect and provide a rationale for why low-intensity steady-state (LISS) cardiovascular training may be a useful tool for those interested in improving their body composition.

This article presents information about assessing speed and agility in a controlled environment with a test that is similar to the actual demands of a specific sport.
