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 examines using the sled as a dynamic correspondence exercise for increasing on-ice acceleration.

Boyd Epley, founder of the National Strength and Conditioning Association (NSCA) and one of the most decorated strength coaches of all time, talks to the NSCA Head Strength and Conditioning Coach, Scott Caulfield, about how the NSCA was founded, how Coach Epley talked Nebraska into letting him weight train all football athletes (most of whom never lifted before), and growing the profession for female strength and conditioning coaches.

Want to break into tactical strength and conditioning? Start by understanding the physical and stress demands of tactical work. Whitney Tramel explains what coaches need to know before stepping into this space. Drawing on her experience across military, police, and fire settings, she outlines the training qualities tactical professionals need to stay ready. She also discusses the growing focus on “holistic health.” In her view, that means looking at the whole individual and supporting longevity across a demanding career. As Tactical Program Manager at the National Strength and Conditioning Association (NSCA) and a PhD candidate studying stress physiology, Tramel connects research with the realities of tactical coaching. She also addresses a side many coaches are not ready for: tactical athletes often trust their strength coach with conversations that reach far beyond training. Learn what the role requires, what coaches often miss, and how to enter the tactical field with clarity.
