Mental fatigue doesn’t announce itself.
It creeps. Then it cracks. Then it costs your athlete their performance.
The Soma Full Stack was built to solve that.
Every athlete has a breaking point — but most coaches don’t know where it is, when it hits, or how to move it.
The Full Stack changes that.
It’s not just training. It’s a complete cognitive operating system — built to stress the brain, track the drift, and rewire resilience under pressure.
This is the flow:
You start with the right task (Cognitive Stack).
You decide when the brain gets hit (Integration Stack).
You control how long it runs (Duration Stack).
You track when performance starts to break (Monitoring Stack).
And you capture the exact impact on performance (Data Stack)
The Stack turns chaos into control.
The Cognitive Stack
The Foundation of Mental Load
This is where the system starts: the task itself.
But not just any task — a scalable cognitive drill that gets harder over time.
The 4 Layers of Load:
THE CORE (The Task)
Simple or complex. Reaction-based or decision-based.
THE GRIND (The Duration)
The longer it runs, the deeper the depletion.
THE PRESSURE (The Intensity)
Speed + precision = chaos.
THE MULTIPLIER (The Mode)
Layered constraints that change the task under load.
This stack turns a drill into a system.
It evolves with the athlete — not against them.
The Integration Stack
Timing the Hit
Most cognitive training happens in isolation.
The Integration Stack changes that — by embedding mental load directly into the physical session.
4 Phases of Integration:
PRE-TRAINING — Burn the brain before the body
INTERMITTENT — Add brain load between sets
CONCURRENT — Body + brain, same time
POST-TRAINING — Drop cognition on top of physical fatigue
Each phase shifts what fatigue feels like — and what it builds.
The Duration Stack
Every Minute Adds Weight
How long a drill runs determines how deep the cost goes.
The Duration Stack gives you tiers of depletion — so you know exactly what you’re building.
The Monitoring Stack
Where Fatigue Hides, This Finds It.
You can’t see mental fatigue until it’s too late — unless you track it.
This stack gives you two tools to spot collapse as it happens:
PVT-B – The Subtle Collapse Detector
Catches drops in focus, variation, and lapses
Use pre- and post-session to track drift
Detects mental fatigue before athletes feel it
PFTT – The Threshold Finder
Shows when cognitive sharpness collapses under physical intensity
Pinpoints the exact second performance flips
Reveals the gap between physical ability and brain control
The Data Stack
Measure What Matters
At the top of the stack sits the output — the data.
This is how you verify progress, adapt training, and find patterns that no stopwatch can show you.
Cognitive Metrics:
Reaction Time
Speed (1000 / RT)
Accuracy
Variation
Rate Correct Score (RCS)
Physiological Metrics:
BPM
rMSSD
SDNN
Minute-on-Minute (MoM)
Track how fatigue builds within the task
Spot which metric collapses first
See how long athletes survive the load before slipping
