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.

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.

This article gives a firsthand account of working in a few of the United States Army’s earlier human performance and injury reduction programs as a strength coach and active-duty physical therapist.

This article aims to share practical application strategies that strength and conditioning coaches can use in fostering a positive change in their athlete’s performance by understanding intrinsic and extrinsic performance motivation and how to adopt an autonomy-supportive coaching style.

This excerpt from NSCA’s Essentials of Sport Science briefly explains workload and injury risk factors.

Female athletes in the United States have made great progress in sports since Title IX was enacted in 1972. Despite the progress they have made, female athletes have yet to gain full recognition for their athleticism and their achievements. The purpose of this article is to break down the stigma female athletes have received over the years and shine light on the differences that make female athletes a reward to train.

Brett Bartholomew, founder of the performance coaching and consulting company, The Bridge Human Performance, talks to the NSCA Head Strength and Conditioning Coach, Scott Caulfield, about learning what drives people, how to interact effectively with others, adapting to change, and the value in learning from other fields.

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.
