# Alpha memo: One Bout of Resistance Training Does Not Enhance Metformin Actions in Prediabetic and Diabetic Individuals

Hypothesis-level alpha signal; not clinical advice.
**Alpha hypothesis:** metformin resistance training may be hiding a metformin / diabetic / not boundary condition: training modulate humoral inflammatory and one bout training does point in different directions.

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

**Evidence bridge:** metformin, diabetic, not, resistance.

**Tension:** null, positive.

**Evidence graph:**
- 10.1249/MSS.0000000000002889 - primary (strongest direct human evidence)
- 10.1111/acel.13039 - mechanism (mechanism context for evidence graph)
- 10.17632/w8rt2r7vx3 - replication (replication context for evidence graph)
- 10.3389/fphys.2022.872745 - consensus (consensus context for evidence graph)
- 10.1249/01.mss.0000764428.80520.ab - boundary (boundary context for evidence graph)

**Receipt roles:**
- 10.1249/MSS.0000000000002889 - null_signal (direct human reversal)

**Claim ledger:**
- 10.1249/MSS.0000000000002889 - null_signal; design=randomized_trial; population=human; outcome=long; direction=null; support=direct/high
- 10.1111/acel.13039 - mechanism; design=randomized_trial; population=human; outcome=hypertrophy; direction=negative/null/positive; support=direct/high
- 10.17632/w8rt2r7vx3 - replication; design=intervention_study; population=human; outcome=unspecified; direction=negative/positive; support=direct/high
- 10.3389/fphys.2022.872745 - consensus; design=randomized_trial; population=human; outcome=hypertrophy; direction=negative/null/positive; support=direct/high
- 10.1249/01.mss.0000764428.80520.ab - boundary; design=randomized_trial; population=human; outcome=chronic; direction=null; 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.
