Wheel Running


Clinical Background

Rodents show a strong circadian rhythm in voluntary wheel running behavior. Wheel running activity is monitored over several days or weeks for the purpose of assessing drug effects on exercise behavior. Wheel running measurements may be used in studies of toxicity, circadian rhythm, and voluntary exercise.
