The purpose of this article is to review the related literature that has explored the influence of resistance training programs on the onset of fatigue and muscular power as it relates to non-contact high-intensity intermittent sports, in order to provide suggestions for creating same-day training programs.
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.

Circuit training is quick and effective way to induce training adaptations that are similar to the demands that tactical officers face in their career. This is a basic layout of a circuit training program that can be implemented to recruits during training to prepare them for the physical demands they will face.
Deloading is widespread, but its application is often inconsistent and undervalued. That gap caught Lee Bell’s attention after discovering there was no consensus definition. Bell is a Senior Lecturer at Sheffield Hallam University who focuses on the deloading, overtraining, and overreaching spectrum. He explains how overtraining and overreaching are sometimes used synonymously. That confusion is compounded further by associations with overtraining syndrome (OTS). Instead, Bell frames overreaching as a “window of opportunity” when used intentionally. For example, a planned overreach can be functional or non-functional based on recovery. Bell also examines opportunities and tradeoffs in modern periodization models. He contrasts flexible and fluid approaches with more traditional, rigid programming; each approach has implications for athlete trust and recovery. Looking ahead, Bell envisions a collaborative approach to sport science driven by coaching needs. He reflects on recent coaching survey data and the key themes that emerged for the future. Hear his perspective on next steps in velocity-based training, individualized periodization, and variability.
