Wheel-running activity was continuously recorded over several days, showing hourly running patterns and cumulative wheel counts across alternating light and dark cycles. ​

Physical activity was monitored by infrared beam breaks in the Promethion indirect calorimeter for one hour in either a mouse with ad libitum access to food or shortly after food removal. (Rubio et al Mol Metabolism 2023)

Go to CalR, a web application for indirect calorimetry analysis. The CalR project: There is a critical lack of standardization for indirect calorimetry experiments to measure body composition ( Corrigan et al eLife 2020, Banks et al Nature Metabolism 2025). Currently, the same dataset can produce...

EchoMRI 3-in-1 Body Composition Analyzer Measures live mice up to 100g, tissue samples (including Zebrafish) of 10g, and biopsy samples up to 0.1g Measurements include lean mass, fat mass, and water mass 5 minutes per mouse No anesthesia required

Optogenetic stimulation of Agrp neurons in ChR2-expressing mice was performed in the Promethion calorimeter, with food intake, metabolic rate, body temperature, and activity measured during the stimulation period.
