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.

This article will examine the physical demands of soccer players and discuss why repeated sprint ability (RSA) is considered highly important in the performance of these athletes.

This article looks to explain why law enforcement recruits have higher incidences of lower extremity bone stress responses and stress fractures. It also explores injury mitigation pathways to increase the graduation rates among law enforcement academies.

This article aims to explain why integrating multiple tests such as Anaerobic Speed Reserve (ASR), Intermittent Fitness Test (IFT), and Maximum Aerobic Speed (MAS) can provide a comprehensive evaluation of soccer players’ fitness levels and help to design effective training programs tailored to their individual needs.

This article explains the connections between the upper and lower body and their influence on performance and recovery strategies in sprinting.

This article consists of five assessments that could be utilized by the tactical facilitator to measure upper- , lower- , and total-body power in law enforcement officers (LEOs). Although the focus of this article is LEOs, the assessments could also be used for other tactical populations.

The purpose of this article is to present normative data that has been previously collected for the 75PR, use the data to create informed training practices, and support the need for further research of this particular topic in law enforcement.

It is important in a coach’s journey to be motivated to find solutions instead of just unimportant problems. Steve Hess shares some of the lessons he has learned in his 21 years with the Denver Nuggets of the National Basketball Association (NBA).
