Gravitational
Force.
A measure of linear acceleration — how quickly the head speeds up or slows down in a straight line during an impact. HIT measures G-Force in real time, giving athletes and coaches precise, objective data on every hit.
Straight-line impact.
Measured precisely.
G-Force measures straight-line impact forces — like a direct blow to the front, back, or side of the head. In the context of head injuries, we're referring to the impact that happens to the skull and brain when someone gets hit, falls, or stops suddenly.
1G is the force of Earth's gravity. So a 30G impact means the head experienced a force 30 times greater than gravity — the equivalent of your head suddenly weighing 150kg instead of 5kg. That's the kind of force HIT is designed to detect, log and act on.
Why It Matters
It's not just one big hit.
It's the total load.
Research increasingly shows that it's not just one big impact that matters — it's the total load over a week or season. Exceeding 600G/week is a significant marker in brain health research. By monitoring linear Gs in real-time, HIT sensors can trigger alerts, support injury assessment, and guide recovery decisions.
Impact Classification
Three levels.
Clear thresholds.
Every impact recorded by HIT is classified into one of three levels — giving instant, colour-coded clarity on severity.
