Nintaijutsu

A combination of Ninjutsu and Taijutsu, it is the style of fighting that Kumogakure Ninja specialize in, most notably the Current Raikage E. It seems you enhance your body with a ninjutsu, like the Raikage's Lightning Release Armor, to enhance their physical stats like speed, or strength, or reflexes. It is possible Killer Bee uses his Jinchuuriki Cloak in such a manner.
