From: Age-specific differences in the time-frequency representation of surface electromyographic data recorded during a submaximal cyclic back extension exercise: a promising biomarker to detect early signs of sarcopenia

Fig. 1

The left part of this figure illustrates the positioning of the SEMG sensors during the test as well as the dynamic exercise in extension (top left) and flexion (bottom left). The right part of this figure illustrates the trunk angular displacement (top), the angular velocity (second row), the raw SEMG data (third row), and IMDF-SEMG estimates (bottom) over the duration of two trunk exercise cycles for concentric (highlighted in red) and eccentric (yellow) phases. Data is shown for a representative subject
