Unloading of an EDLat tendon by a MU. Simultaneous tension records of EDLat’s three tendons are shown during a single twitch (A) and during tetanic stimulation at 20 Hz (B, C) of a single MU that unloaded the t4 tendon while exerting tension on the t3 and t5 tendons. In the single twitch (A) and in the high gain record (C), tension in the t4 tendon can be seen to decrease with each increase in tension in the other two tendons. Horizontal calibration bar = 0.5 sec; vertical calibration bar = 1.51 gm-wt in A, 2.36 gm-wt in B, 0.30 gm-wt in C.
