Figure 1From: Whole body oxygen uptake and evoked knee torque in response to low frequency electrical stimulation of the quadriceps muscles: V • O 2 frequency response to NMESSample torque and oxygen uptake record. (a) Measured joint torque and (b) rate of oxygen consumption V . O 2 for a representative subject over the 60 minute test period showing 4 minute bouts of NMES at selected frequencies. Inserts, (c through e), show torque responses on an enlarged time-scale so that partial twitch fusion can be seen.Back to article page
