# Metformin and Exercise Training Interaction

## Signal

Physical activity and metformin may have a synergistic effect on leptin in colorectal and breast cancer survivors. [R1]

## Update

Metformin attenuated metabolic insulin sensitivity and insulin-stimulated carbohydrate oxidation following high-intensity exercise training. [R2]

## Synthesis

While metformin and exercise both impact metabolic biomarkers in cancer survivors, metformin may blunt specific insulin-sensitizing effects of high-intensity training in adults at risk for metabolic syndrome. [R1] [R2]

## Falsifier

Compare metabolic insulin sensitivity changes in high-intensity exercise cohorts with and without metformin administration. [R1] [R2]

## Receipts
- [R1] Multicenter, randomized phase II trial of physical activity (PA), metformin (Met), or the combination on metabolic biomarkers in stage I-III colorectal (CRC) and breast cancer (BC) survivors. (2017). DOI: 10.1200/jco.2017.35.15_suppl.10059.
- [R2] Metformin attenuates metabolic insulin sensitivity and insulin-stimulated carbohydrate oxidation after high-intensity exercise training in adults at risk for metabolic syndrome. (2026). DOI: 10.1111/dom.70478.

## Status

Challenger output. Every factual claim is receipt-bound; the falsifier is a proposal, not evidence.
