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.

Research shows that the appropriate integration of resistance training into the endurance athlete’s training can result in significantly better performance when compared to classic endurance training plans that focus only on aerobic endurance.

Building athletes who are strong, healthy, and resilient requires more than sets and reps, starting with a shift in mindset. Christi Edson, Head of Performance for the Orlando Pride in the National Women’s Soccer League (NWSL), shares how she integrates strength and conditioning with sport science to sustain athlete health and performance. She reflects on the field’s evolution from the well-known “Bigger, Faster, Stronger” program to a training culture emphasizing resilience, active recovery, and durability. Drawing from her experience coaching high school athletes to NWSL professionals, Edson highlights the adaptability and creativity coaches need. Those qualities help her to develop athletes who can thrive through a demanding 11-month season. She details how tools like GPS, force plates, and velocity-based training sharpen communication and reshape expectations in the gym. Her story points coaches toward the future of athlete development: collaboration, precise load management, and long-term health as the foundation of strength.

This article details the rationale for making the eight main movements the foundation of tactical strength and conditioning.

There is no argument that periodization is successful, and that different models can be applied with success in different fashions. The question of how shift work really affects a periodized program—more specifically firefighter shift work—is less clear.

The purpose of this article is to provide an example of a resistance training program for improving performance and reducing the possibility of injury for pickleball players.

The purpose of this article is to present the reader with the prescription of a daily specific stretching routine that can help athletes avoid the onset of injuries and chronic pain in muscle-tendon structures of the lower extremities.

This excerpt from the Essentials of Strength Training and Conditioning outlines what training typically looks like in the preparatory period, or off-season.

This excerpt from the book Developing Endurance, published by Human Kinetics, presents a sample 5K training plan for runners.

Scenarios that provide a stimulus relevant to the sporting environment may help athletes develop better anticipation skills through the refinement of search strategies, response speed and accuracy, pattern recognition, and decision-making abilities.
