What's a bad fatigue score?Updated 2 months ago
A bad Fatigue Score means your arm lost too much strength after throwing—putting you at higher risk for injury, velocity loss, and poor performance.
Fatigue Score Breakdown:
- >10% strength loss post-throwing = Concerning
Your arm isn’t handling the workload well and needs recovery. - >20% strength loss = Major Red Flag
Severe fatigue. Immediate action is needed—reduce throwing and boost recovery efforts.
Why Fatigue Matters:
Fatigue is the #1 injury risk.
Research shows a fatigued arm is 36x more likely to get injured.It breaks down mechanics.
A tired arm can’t stabilize properly, leading to compensations that stress the elbow and shoulder.Performance takes a hit.
Fatigue kills arm speed—expect lower velocity, shaky command, and inconsistent release points.
Tracking fatigue through post-throwing exams helps you make smart decisions, protect your arm, and stay consistent all season.
