Fig. 6. Power density spectrum of the system.

Fig. 6

Superimposed power density spectrum either in position clamp (red circles interpolated by the red Lorentzian curve), or in length clamp with the array of actin attached motors in rigor from both fast muscle (violet circles and curve) and slow muscle (cyan circles and curve). The upper − 3 dB frequency fc is: 59 ± 3 Hz (red), 31 ± 6 Hz (violet) and 17 ± 3 Hz (cyan). The coloured area delimited by thinner lines indicates the confidence limits.
