I am laughing so hard steve lands so lightly on his toes like a damn ballerina and bucky just drops like a ton of bricks on that car and fucking CRUSHES IT
So, in parkour, there is a practice of trying to land as quietly as possible. This is because landing lightly and softly absorbs the energy from the impact into the muscles as opposed to the bones where they may do some hard damage.
So, by landing lightly on his feet, Steve is employing good practice, showing training that works with his body, to get the most out of his super-soldierity.
However, the Winter Soldier lands harshly and without regard to the well being of his body. His objective is only the kill, and he will sacrifice his body and push through considerable pain to complete his mission.
That got sad real fast
just to highlight the difference between the winter soldier’s movements and bucky’s.
