Education
Watch a sarcomere shorten and see why the A band stays the same while the I band and H zone shrink, which is the heart of the sliding filament theory. Force depends on filament overlap in the classic force-length curve and on speed in Hill's force-velocity relation, and a calcium transient turns single twitches into fused tetanus as the stimulus rate rises. Remove ATP to see rigor, remove calcium to see relaxation.
