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.

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.

This brief excerpt from NSCA’s Essentials of Sport Science discusses skill-based key performance indicators (KPIs).

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.
