# Alpha memo: cold / immersion / strength

**Alpha hypothesis:** cold water immersion resistance training adaptation may be hiding a cold / immersion / strength boundary condition: does water attenuate adapt and adaptation water point in different directions.

**Signal score:** `100` (novelty `58`, evidence `96`)

**Evidence bridge:** cold, immersion, strength, training.

**Tension:** negative, positive.

**Evidence graph:**
- 10.1123/ijspp.2019-0965: counter (candidate evidence stream)
- 10.1519/JSC.0000000000000434: primary (candidate evidence stream)

**Receipt roles:**
- 10.1123/ijspp.2019-0965: negative_signal (candidate evidence stream)
- 10.1519/JSC.0000000000000434: positive_signal (candidate evidence stream)

**Claim ledger:**
- 10.1123/ijspp.2019-0965: negative_signal; design=randomized_trial; population=unspecified; outcome=performance; direction=negative; support=indirect/medium
- 10.1519/JSC.0000000000000434: positive_signal; design=unspecified; population=unspecified; outcome=long/setting/short; direction=positive; support=indirect/medium

**Why it matters:**
This is a receipt-bound lead for investigation: two independent search hits share a non-obvious bridge term, so the memo can test whether that bridge explains a boundary condition or a new angle.

**What would falsify it:**
A follow-up search fails to find direct receipts where the bridge term and both evidence streams appear in the same source-grounded claim, or the apparent connection collapses to one duplicated source.

**Safety note:** This memo is an alpha hypothesis. A later LLM writer may sharpen prose, but it may not add claims beyond the receipts above.
