During voluntary muscular contractions, the CNS controls muscle force by varying number of motor units recruited, types of motor units recruited (FT vs.
Therefore, future protocols should include low frequencies in combination with longer pulse durations and higher voltages to maximize motor unit recruitment and minimize metabolic demand of recruited motor units.
EMG signals are essentially made up of superimposed motor unit action potentials [MUAP's] from several motor units.
Since momentum reduces muscular tension, it can limit total motor unit recruitment and also increase accelerative forces that can potentially create muscle and/or joint injury.
In some IBID versions, recharging power IBID supplied to the moving motor unit through a flexible cable, which is held in tension by a counterweight traveling inside the aluminum track.
Changes in surface-detected motor unit potential (SMUP)--an indicator of mobilization units of nerve roots (Stashuk, 1999)--after 8 weeks of resistance training are presented in Table 3.
It was hypothesized, however, that perhaps the strength-trained athletes had improved the ability to synchronize motor unit firings, which would increase the relative power in the low-frequency portion of the EMG spectrum [8].

Seiko used its aspheric lens design technology to lower the overall height of the lens and utilized an upgraded linear motor unit for an actuator to accomplish the thickness of 6mm.
The generator attaches to the motor unit by means of a new motor collar design that also allows the operator hands-free ejection of the used generator, minimizing the chance of operator contamination when attaching the next generator.
