In this work, we designed and constructed an inexpensive MR compatible ergometer that can be used for studying lower leg muscle metabolism. This ergometer allows subjects to perform a plantar flexion exercise protocol while 31P-MR data are acquired. The device is easy to use, and it can be positioned inside the bore of the magnet in less than 10 min. The mechanical power exerted by the subject can be estimated from force and angle displacement signals that are continuously monitored, while the exersice intensity can be varied by changing the number and/or the material of the resistive elastic cords.
