The following set up represents an isolated skeletal muscle with an attached 0.5g weight. The muscle is stimulated once with 8.5V, and the resulting distance the weight movesover time is recorded. Which of the following can you conclude based ONLY on these results?ESimulated Ruler (mm)5gDistance (mm)17N0 20 40The muscle contracted isometricallyThe muscle experienced fatigue after 80 msecThe muscle generated maximal tetanic tension at 40 msecThe muscle contracted isotonically100 120 140 160 180 200Time (msec)

Since the length of the muscle changes in the process, it is an isotonic contraction.
