Recovery Research Desk

The working file on Recovery. Each claim below is rated on its own evidence.

In plain terms: every claim below has been checked against the published research and rated on how solid the evidence actually is, not just asserted. Established means multiple strong studies agree. Uncertain means the evidence is thin or conflicting. This file updates as new research comes in, so you can see exactly what's settled about Recovery and what isn't. See exactly how a study becomes this rating: How KnowYourPrime Works.

Do consumer wearable recovery/readiness scores measure what they claim to measure accurately?
§
KnowYourPrime evidence rating Emerging Evidence currently favors the claim, but more confirmation is needed.

Consumer wearable composite recovery/readiness scores and their underlying heart rate-based nocturnal metrics can be measured accurately enough to be meaningful.

  • Anchor-grade evidence affirms the core relationship.
  • An anchor study is present but its own reported finding does not cleanly affirm this claim, so it does not count toward the Established threshold.
  • The claim rests on a single anchor whose finding affirms it; a second independent affirming anchor is needed to reach Established.
