torque output
The torque output in a permanent magnet brushless DC motor (BLDCM) is usually controlled by regulating the motor phase currents.
      
Since the GAS muscle crosses the knee joint, flexion of the knee reduces the length of this muscle, thus limiting its contribution to torque output.
      
By comparing the pulses with the visual input the system continuously measures and adjusts the efficacy of the torque output.
      
A secondary purpose was to compare the method error associated with maximal voluntary concentric and eccentric torque output over a range of testing velocities.
      
The effect of β-adrenergic blockade on torque output and leg blood flow was examined in seven healthy young men during repeated maximal isometric voluntary contractions of the triceps surae muscle group.
      
Torque output decreased during the 10-min contractions with no differences between the four drug treatments.
      
Compared to LS, HS had significantly greater estimated lean body mass (+ 10.2 kg) and approximately 25% greater average torque output.
      
Statistical analysis revealed that torque output in LS plateaued at low concentric velocities and was also flattened with increasing eccentric velocities.
      
The aim of this investigation was to study the relationships among movement velocity, torque output and electromyographic (EMG) activity of the knee extensor muscles under eccentric and concentric loading.
      
Neither torque output nor EMG activity for the three muscles changed across eccentric test velocities (P >amp;gt; 0.05).
      
Torque output per unit EMG activity was clearly higher for eccentric than for concentric conditions and the difference was of similar magnitude for all groups.
      
Effect of prior isometric muscle action on concentric torque output during plantar flexion
      
The influence of different levels of prior isometric muscle action on the concentric torque output during plantar flexion was examined at two angular velocities (60°·s-1 and 120°·s-1) in ten healthy female subjects.
      
A KINetic-COMmunicator II dynamometer was used to measure torque output during plantar flexion within a range of motion of 78°-120° of the ankle joint.
      
Up to 75% of MVIC, the torque output in the first part of the range of motion increased with the level of the prior isometric muscle action; at higher levels of MVIC the torque did not appear to increase any further.
      
It would seem therefore that the increase in torque output early in the range of motion cannot be explained on the basis of differences in electrical muscle activation in this study.
      
This study aimed to investigate the concentric torque output with and without preceding eccentric or isometric actions in patients with upper motor neuron lesions due to cerebro-vascular disease.
      
Knee-torque output and M-wave variables (amplitude, latency, duration, and root mean square, RMS) of two muscular heads of the quadriceps were recorded in 19 paraplegic patients during a 120-s isometric contraction.
      
SVA trials were performed with direct visual feedback of the SOL electromyogram (EMG) at a level resulting in a torque output of 30% of isometric maximum.
      
The aim of this study was to investigate the position and velocity dependency of the strength (torque) output of lateral flexor muscles of the trunk.
