Physical performance depends on the reliable functioning of the metabolic exercise testing system. In sport in particular, maximum physical performance can only be achieved if metabolism can be adapted to the demands of training.

First, this requires regular medical monitoring of the exercising individual and, secondly, training results must be objectively measurable so that training exercise schedule can be rapidly adapted.

METAMAX®metamax


Is a mobile, mains independent indoor and outdoor metabolic exercise testing system for sports and exercise science as well as for occupational medicine. Thanks to the bidirectional wireless transmission and battery operation you can obtain previously unachievable freedom for your application. This means: put it on, connect it and measure it.

  • Maximum measurement precision as a result of cutting-edge sensor technology and rapid calibration
  • Extremely compact design, carefully designed body attachment and light weight (570 g including battery)
  • Mains-independent operation for up to 15 hours
  • Wireless range up to 1.0 km
  • Respiratory gas analysis using the breath-by-breath or mixing chamber methodology
  • Patented bidirectional transfer of test data and audio feedback for effi cient management of the test subject
  • Measuring the heart rate with a chest strap and recording the heart function with a 3-channel or 12-channel ECG
  • Cutting-edge GPS technology to determine speed and altitude
  • Integration of blood pressure devices and pulse oximetry system
