Muscular rest and gap frequency as EMG measures of physical exposure : the impact of work task and individual related factors / Catarina Nordanger... [et. al.]
Sumario: Owing to an orderly recruitment of motor units, low threshold type of fibres are presumed to be vulnerable in contractions of long duration. To study load on these fibres muscular rest was registered as the time fraction of electromyographic (EMG) activity below a threshold. Moreover, the frequency of periods with muscular rest, EMG gaps, was derived, since a low gap frequency has been shown to be a risk factor for musculoskeletal disorders
