Book One: The Energy You Can See

You already know more about energy than you think.Every time youwatch a slapshot bend the net, feel the roar of a crowd vibrate through yourchest, or notice that the ice plays different in the third period than it didin the first—you’re experiencing the energy systems that run the game ofhockey. You just never had the language for it.

‍The Energy You Can See is the first book in the Ha-Ki Energy Trilogy, and it begins with a simple invitation: walk into the arena and see it differently. Through ten chapters that move from puck physics to ice mechanics, from sound waves to thermal layers, from the force of a body check to the speed of light off a skate blade, performance coach Pierre DeBar reveals the science hiding in plainsight at every hockey game.

This isn’t a textbook. It’s a conversation. Written for players, parents, and coaches, The Energy You Can See proves that you already understand the fundamental energy principles that shape performance—you just haven’t connected them yet. Once you do, the rink never looks the same.

Book Two: The Energy Within

Your body is running a performance system more sophisticated than anything science has built. And most players have no idea how it works.

‍The Energy Within takes you inside the engine room—the biological systems that power everyshift, every decision, every thought you have on the ice. From the three fuel systems that determine why a 45-second shift isn’t arbitrary coaching but precise biology, to the neural pathways that explain why “muscle memory” is a myth, to the heart-brain highway that turns a single breath into a performance tool—this book maps the energy you carry in your body with the same clarity that Book One mapped the energy in the arena.

You’ll learn why your thoughts literally change your blood chemistry. Why sleep is a more powerful performance enhancer than any supplement. Why the stress response that feels like it’s ruining your game is actually rocket fuel that’s been mislabeled. And why the player you’ll be next season is being built by thec hoices you make today.Written for hockey players at every level—and for the parents and coaches who want to understand what’s really happening inside the athletes they support—The Energy Within turns biology into a competitive advantage you can train, direct, and build on for life.

Book Three: The Energy Between

No one plays alone.

Every moment on the ice, your nervous system is connected to the nervous systems of everyone around you—teammates, opponents, coaches, the crowd—through an invisible web of mirror neurons, emotional contagion, and energy transfer. The Energy Between maps this third dimension: the relational energy that turns five individuals into a team, a locker room into an ecosystem, and a building full of strangers into a single roaring organism.

Why does one player’s calm on the bench spread to the players beside them? Why does the car ride home leave a deeper imprint than the game itself? Why do linemates who “have chemistry” literally synchronize their brainwaves? And what determines whether the energy you leave behind in the people you touch builds them up or wears them down?

The Energy Between completes the Ha-Ki Energy Trilogy with the dimension that matters most: connection. Written for players who want to lead, parents who want to support without damaging, and coaches who want their influence to outlast any season—this book reveals the science of the spaces between people and the extraordinary power of the energy that flows through them.
