What was done
Running wheels were placed in outdoor natural environments to observe whether wild mice voluntarily use them without extrinsic rewards, testing whether running wheel activity is purely an artifact of captivity.
What was found
The abstract reports no numerical values, exact sample sizes, or duration statistics. Wild mice frequently used the running wheels in the wild without extrinsic rewards, and their running bout lengths matched those observed in captive mice.
Why it matters
This indicates that wheel running is an elective, natural behavior rather than purely captive neurosis, supporting the construct validity of running wheel models in exercise research.
Limits
The abstract reports no quantitative metrics, sample sizes, or duration details. Findings are restricted to wild mouse behavior and do not directly translate to human clinical outcomes.
