Readiness Score

Daily composite score indicating physiological readiness for physical and mental exertion, guiding training and recovery decisions. Readiness algorithms integrate multiple overnight biomarkers: heart rate variability (higher HRV = better recovery), resting heart rate (lower = better recovered), sleep quality and duration, respiratory rate, body temperature deviation, and previous day's activity load. Scores are typically personalized to individual baselines established over 1-2 weeks of consistent wear. High readiness suggests the autonomic nervous system is recovered and prepared for intense training; low readiness indicates accumulated fatigue or stressors requiring rest or light activity. Readiness scores support periodized training by identifying optimal days for hard workouts versus recovery. Factors beyond exercise affecting readiness include alcohol, illness, travel, psychological stress, and sleep quality. Some platforms provide activity recommendations based on readiness. While readiness scores synthesize complex physiology into actionable guidance, they remain estimates—users should integrate readiness data with subjective feelings and training goals.
