Sleep, soreness and the limits of recovery scores

First published:
Research through: 18 September 2026
Two checked papers from 12–18 September add context, not a new prescription. Wearable strain and perceived effort were weakly related in a small sample, while a soreness review did not establish a superior recovery treatment.
Selected historical recovery; not an exhaustive account of all research published that week.
Topics: Training, Recovery
Finding
Across paired observations from 11 female college athletes, perceived exertion and a proprietary wearable strain score were only weakly correlated.
Limitations: Small observational sample, proprietary metrics and no ultra-performance outcome.
Evidence level: Emerging evidence
Finding
A broad review described interacting tissue, inflammatory and neural contributions to exercise-related soreness without establishing a superior recovery treatment.
Limitations: Populations and methods were heterogeneous, and extractable effects were insufficient for a new meta-analysis.
Evidence level: Moderate evidence
Interpretation
Judge readiness from sleep, symptoms, perceived effort and comparable-session trends rather than one device score. Reduced soreness alone does not prove restored function or better 100K performance.
