Explanations of the Key Metrics in the App
The Strength Imbalance Score compares the strength of the front-side muscles (used for acceleration) to the back-side muscles (responsible for deceleration and stability). Ideally, these muscle groups should be balanced, with a ratio close to 1.0. Si
ArmCare measures fatigue and recovery by tracking changes in strength over time using the fresh and post-throwing tests. These measurements help determine whether an athlete is ready to throw at full intensity, needs workload adjustments, or is at ri
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 is the #1 injury risk.Research shows a fatigued arm is 36x more likely to get injured. It bre
The Arm Score is a measure of your total throwing arm strength relative to your body weight, providing a simple way to evaluate arm health and durability. It is calculated by summing the strength of the key muscle groups for throwing and expressing i
Strength-to-Velocity Ratio (SVR) is another key performance metric that represents how efficiently your strength translates into throwing velocity. The ideal SVR target is 1.6 pounds per mph of throwing velocity. If your SVR is too low, it may indica
The ArmCare App’s Player Report Card allows you to compare your results against other athletes at your level, providing insight into how your arm strength stacks up against your peers. Key metrics for comparison include:. Arm Score: This is a measure
