Performance Metrics Science

Understanding how we calculate athlete readiness, recovery, and engagement

Readiness Score

The Readiness Score (0-100) measures how prepared an athlete is for training by combining wellness check-ins with training adherence and recency.

R = 0.5 \times W + 0.3 \times C + 0.2 \times R_c

Where:

• $R$ = Readiness Score (0-100)
• $W$ = Wellness score from athlete self-report (muscle, energy, sleep, mental, mood)
• $C$ = Workout completion percentage in selected period
• $R_c$ = Recency score from days since last activity

Optimal Range: 75-90 (ready for normal training intensity)

Concerning Range: Below 60 (consider recovery or modified training)

Recovery Score

The Recovery Score (0-100%) indicates how well an athlete has recovered from previous training stress. It uses an exponential recovery curve modified by training intensity and volume.

Recovery = 100 \times (1 - e^{-kt}) \times I_m \times V_m

Where:

• $t$ = Hours since last workout
• $k$ = Recovery rate constant (0.04)
• $I_m$ = Intensity modifier (0.85-1.1)
• $V_m$ = Volume modifier (0.9-1.0)

Full Recovery: 48-72 hours (>95%)

Adequate Recovery: 24-48 hours (70-95%)

Engagement Score

The Engagement Score (0-100%) measures athlete commitment through training adherence, consistency, and workout quality. It provides insight into long-term training success predictors.

E = 0.4A + 0.3C + 0.3Q

Where:

• $E$ = Engagement Score (0-100%)
• $A$ = Adherence Rate (completed/scheduled workouts)
• $C$ = Consistency Factor (1 - skip rate)
• $Q$ = Quality Score (duration compliance)

Elite Range: 85-95% (optimal for performance gains)

Concerning Range: Below 70% (risk of detraining)
