Telemetric Metabolic Treadmill for Heart Rate and VO2 max

Our Oxymax and Metabolic Treadmill have long been the gold standard for measuring VO2 max in mice and rats. But telemetric measurements have always proved difficult on a treadmill. Static and motor electrical-noise have always interfered with the signal. But we have recently developed a special antenna for our treadmill that produces a clear signal for core body temperature and heart rate. Coupled with our Oxymax software, readings are recorded at 5-second intervals for heart rate, temperature, VO2/VCO2, RER, and energy expenditure. Also, all experiment parameters like treadmill speed and/or angle (requires the motorized incline option) are programmable from the software.
