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 is intended to provide an understanding of the demands of football from a bioenergetic perspective and provides a framework in which strength and conditioning professionals can design conditioning plans that focus on preparing athletes for competition.

This article is part of a continuing series on practical, evidence-based approaches to reducing the risk of injury while developing tactical strength and conditioning.

The purpose of this article is to provide fitness professionals with best practices on creating a program that uses red light therapy to aid in weight loss and weight management.

Courteney Benjamin and Yasuki Sekiguchi, from the Korey Stringer Institute, talk to the NSCA Head Strength and Conditioning Coach, Scott Caulfield, about preventing sudden death in the heat and how coaches can plan ahead, create, and respond with an emergency action plan.

As consumers embrace technology, they are also expecting that same incorporation of technology into their exercise programs. This article shares how some top trainers are meeting this need.

When isolating aerobic capacity as a determinant of performance, traditional interventions have focused on increasing an individual’s VO2max. Based on the large acute improvements from a single positive psychology research study, investigations into the application of integrated psychophysiological strategies to optimize performance should be explored.

Musculoskeletal injuries are the primary source of disability in the United States military. With the integration of movement screens and the implementation of tactical strength and conditioning facilitators there can be success in reducing the amount of musculoskeletal injuries in the tactical populations.

This article explores what a facility-level culture may look like, identifies some of the expected benefits of purposely developing that culture, and discusses some misalignment between what coaches say they want the culture to feel like and the message the athletes are likely to receive.

This three-part series will show how personal trainers can create a physically literate cradle-to-grave culture for all, with LTAD as the framework. This article addresses awareness of LTAD and why is it important for personal trainers.
