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.

The purpose of this article is to identify considerations that are to be taken into account when designing and implementing an annual training program for firefighters, as well as to discuss strategies for implementation.

An evidence-based movement assessment could hold Marines accountable for mobility and stability by systematically assessing movement patterns. This article (part three of a four-part series) explains one way that this could be accomplished.

This article describes the transition from the Army Physical Fitness Test (APFT) to the Army Combat Fitness Test (ACFT), as well as the detailed events that make the ACFT.

The purpose of this article is to emphasize the critical need for a nutrition strategy that aligns with the specific demands inherent in the sport of soccer.

Despite best efforts, musculoskeletal injuries among active duty service members continue to be pervasive and on the rise. Tactical facilitators can each do their part as a member of one team to avoid the injuries that are preventable and to rehabilitate, recondition, and optimize performance in the ones that do occur and are treatable.

The exercises and progressions provided in this article can be used as a basic guideline for rehabilitation of common shoulder injuries, as well as a way to strengthen areas that are commonly affected by injury.

The purpose of this article is to shed light on the most current work that has been done in examining various dietary approaches to improving markers of cardiometabolic health and performance among high-stress occupations, such as firefighters, as well as the need for additional work in this area.

The excerpt from Strength Training for Soccer describes the movements necessary for multidirectional speed.
