Receipt 1 measures a *chronic* outcome (12 weeks, twice weekly, physically active men) and reports a *negative* adaptation effect, driven by blunted hypertrophy signalling and satellite cell activity in the first two post-exercise days. Receipt 2 measures a *short* block (2 × 4 weeks, 16 sessions, resistance-trained men) and reports *no* positive benefit on muscle function, perceptual markers, or architecture (notably fibre pennation angle, isometric peak force, 1/4 squat). Both point in the same direction against CWI as a recovery accelerant; only one says it is *worse than doing something else*. The \"longevity\" framing risks importing a wellness hypothesis the receipts do not support: neither paper isolates long-horizon health endpoints."},{"id":"claim_2","type":"claim","text":"For athletes, clinicians, and consumer recovery-product channels, the actionable read is comparator-dependent. The negative finding is anchored to an *active* recovery control and 12-week hypertrophy (10.1113/jp270570). The null is anchored to a sham/thermoneutral control and 8 weeks of lower-body work (10.1519/jsc.0000000000004097). A boundary condition worth flagging as a hypothesis: benefits in *training-adaptation* terms (hypertrophy, strength, fibre-level morphology) are the dimension under attack, not recovery comfort. Cross-domain transfer to \"longevity\" or recovery-product positioning is unsupported by these receipts."},{"id":"claim_3","type":"claim","text":"10.1519/jsc.0000000000004097 — 2 × 4-week lower-body resistance training trial; CWI vs sham; null on function, perception, and muscle architecture (pennation angle, isometric peak force, 1/4 squat)."},{"id":"source_1","type":"source","study":"Post-exercise cold water immersion attenuates resistance-training adaptations","year":null,"doi":"10.1113/jp270570","url":null,"population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"primary"},{"id":"source_2","type":"source","study":"Cold water immersion versus sham during resistance training: function, perception, and architecture","year":null,"doi":"10.1519/jsc.0000000000004097","url":null,"population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"primary"}],"edges":[{"from":"d485da0e-64a3-4db3-ad4e-b88a0f12081f","to":"claim_1","type":"contains_claim"},{"from":"d485da0e-64a3-4db3-ad4e-b88a0f12081f","to":"claim_2","type":"contains_claim"},{"from":"d485da0e-64a3-4db3-ad4e-b88a0f12081f","to":"claim_3","type":"contains_claim"}],"screening":{"identified":2,"screened":2,"excluded":0,"included":2,"included_or_retained":2,"flow":["identified","screened","excluded_with_reasons","included"],"wording":"2 candidate receipts retained after source retrieval, deduplication, and topic filtering.
