Organizational Partnerships
Most organizations implement youth sports at scale with no shared developmental language. The Speed Window gives your staff, your coaches, and the families they serve a single framework: grounded in the science, packaged for practical use.

Strategic Partnerships
If you are thinking about something larger: a league-wide rollout, a co-branded curriculum, or an ongoing relationship. We want to hear about it.
Strategic partnerships are built around what each organization actually needs. There is no standard package at this level. The conversation is the starting point.
Where This Comes From
Long-term athlete development is not a new idea. The research on trainability windows, nervous system periodization, and developmental sequencing has been established in sport science for more than twenty years. What has been missing is a version of it that coaches can implement on a Tuesday morning, that parents can understand in a conversation, and that organizations can adopt without a full curriculum overhaul.
The Speed Window is that version. It is a published framework: a full-length book backed by decades of research, grounded in the author's own developmental history, and organized around three trainability windows that every effective long-term development system is built on. The book is the foundation. The training library, the coaching resources, and the organizational partnership all extend from it.
Organizations that bring this framework in are not adopting an experiment. They are giving their staff a shared vocabulary for what they are already trying to do.
The Book
Written by Matthieu Brunelle. Published by Foundations First Athletics. Available August 1, 2026. The foundational text behind every resource on this site, and the most practical entry point for any coach or organization adopting the framework.
The Framework
The Speed Window maps the three developmental periods when a young athlete's body is primed for specific kinds of training. Organizations that understand the sequence stop making the errors that cost athletes their development.
Window One
Ages 7 to 12
The nervous system is in its most adaptable period. Coordination, rhythm, balance, and movement pattern acquisition happen faster here than at any other stage of development. This is not the time to specialize or load. It is the time to build the coordination foundation everything else will stand on.
What this means for your program: Athletes in this window need multi-directional movement, variety, and skill exposure, not early specialization or intensity.
Window Two
Ages 12 to 15
Growth disrupts movement. Bones lengthen faster than nervous systems and muscles can remap. An athlete who looked fluid at ten can look awkward at thirteen. Not because they regressed, but because development arrived on schedule. This window is when mechanics must be reinforced before any serious load is added.
What this means for your program: This is the highest-injury-risk window. Programs that push load here without addressing mechanics pay for it in ACL tears and early dropout.
Window Three
Ages 15 to 18
After growth stabilizes, the body is finally ready to receive serious strength and power training. Organizations that rush to this window produce athletes who plateau early or get injured. Organizations that arrive here on schedule, with mechanics intact and movement patterns built, produce athletes who are still improving at eighteen.
What this means for your program: The athletes who thrive at eighteen are almost always the ones whose early training stayed in the right window.
The Organizational Case
The problem in most organizations is not that coaches don't believe in development. It is that without a shared framework, belief does not translate into consistent practice.
Coaches
When a coach understands the window they are working in, they can explain why a nine-year-old is doing coordination work instead of strength work, and why that is right. That explanation is worth more to a parent than any result on a scoreboard. The book gives coaches the language. The drill library gives them the sessions.
Parents
Most parent pressure in youth sports comes from families who don't understand what development looks like. They measure by playing time, stats, and tournament results because no one has given them a better lens. The Speed Window gives families that lens, and every parent who reads it becomes a better advocate for what your coaches are trying to build.
The Program
A framework that lives inside one coach's head is fragile. A framework written in a book, deployed through a training library, and reinforced through parent education is an organizational asset. It survives staff turnover. It scales to new age groups. It gives your program something most competitors in your market cannot point to: a system with a name and a rationale.
Building the Evidence
LTAD methodology is not proprietary. The science has been public for twenty years. What no competitor can replicate is longitudinal data from your athletes.
Organizations that implement The Speed Window framework and track athlete outcomes over time are building the only kind of evidence that matters to parents, boards, and governing bodies: proof that it works in practice, with real athletes, in their community.
Foundations First Athletics works with partner organizations to establish simple assessment protocols. No specialized equipment, no complicated testing infrastructure. Baseline coordination and movement quality assessments, tracked over one to three training years, produce the kind of data that makes a developmental philosophy credible at scale.
This is not a requirement for working with us. It is an option for organizations that want to invest in their own long-term positioning. The book and the framework are available independently of any outcomes agreement.
30–50
Athletes tracked longitudinally over a single training year produce meaningful outcomes data: enough to demonstrate developmental trends and inform program decisions.
3 yrs
Three years of consistent tracking produces what no methodology document can provide: evidence that a specific framework produces specific results in a specific context.
Year 1
Organizations that begin tracking alongside book launch will have a full training year of data before the market catches up to the conversation.
Who This Is For
The framework works at any organizational scale. What differs is how implementation is structured, and what a partnership with Foundations First Athletics looks like in practice.
Multi-sport or single-sport clubs serving athletes ages 7 to 18. The framework aligns age groups under one developmental philosophy and gives coaches across your entire staff a shared training language. Bulk book programs put the methodology in the hands of every family you serve.
Middle and high school athletic departments, including district-wide offices, that want a developmental framework spanning the full 7-to-18 continuum. The book works as required reading for coaching staff and as a parent education resource for every program in your system.
Regional leagues, national sport associations, and governing bodies that want to codify a developmental philosophy across affiliated clubs. The Speed Window can serve as the foundational text for a coach education curriculum or a league-wide parent communication initiative.
What Working Together Looks Like
There is no fixed package. Organizational partnerships are designed around your program's size, structure, and goals. The conversation determines the shape of the engagement.
The most direct entry point. Organizations that put the book in the hands of every coach on their staff and make it available to families create the shared language immediately. Bulk pricing is available for orders of 10 or more copies. Contact us to discuss volume arrangements ahead of the August 1 launch.
Partner organizations receive drill cards, window reference guides, and parent education materials co-branded with their program name alongside the Foundations First framework. Resources your coaches can use in sessions and your families can take home. Your credibility, backed by the methodology in the book.
A structured walkthrough of the three-window framework for your coaching staff, live or virtual, led by Matthieu Brunelle. Designed to give every coach in your organization a working fluency in the methodology, not just a familiarity with it. Available as a one-time session or an ongoing engagement.
For organizations that want to build the evidence layer: a structured outcome tracking protocol, baseline and follow-up assessment design, and a co-authored report at the end of each training year. This is how organizations that are serious about developmental methodology build the only credential that lasts: outcomes data from their own athletes, in their own program, over time. This tier is designed for organizations committed to a multi-year engagement and willing to dedicate a staff member as the internal point of contact for the framework.
