PART 1: Satsuki Kiryuin's peak physical condition. While Saretha is in good shape, Satsuki was a fighter, with incredible strength, speed, and stamina. That strength in particular is well, well above the human norm.
PART 2: The remainder of Satsuki's fighting skill.
These two things are connected because her skill and strength goes hand in hand. Satsuki was capable of matching blows with people transformed by Life Fibers, the impacts destroying scenery around them, and even creating localized whirlwinds with the flick of her wrist. The way they were displayed, these are a combined result of these things.
As an added effect, since Junketsu transformed augments Saretha's strength, becoming stronger at her base level will only make her that much stronger when transformed.
