Isometric twitch durations as functions of active stress at 3 Hz stimulation. Time courses of the contraction phase (A and B) and relaxation phase (C and D) and their sum (E and F) of the isometric twitch, quantified at 5% (t₅) and 50% (t₅₀) of peak stress. Data from a representative trabecula from the Control group (open symbols) and from the STZ group (filled symbols) (left panels) and the average relations for n = 15 Control (thin lines) and n = 12 STZ (thick lines) trabeculae (right panels).
