This book excerpt is an overview of the fundamentals to sprinting mechanics and technique. It also covers starting, acceleration, drive phase, recovery phase, and deceleration.

Every client should participate in a 20 – 30 min initial interview and consultation prior to participating in any physical activity. This process allows the personal trainer and client time to complete the strategy session form, physical activity readiness questionnaire (PAR-Q), professional liability form, and trainer-client agreement.

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.
