A kick is a physical strike using the foot, leg, or knee (the latter is also known as a knee strike). This type of attack is used frequently by hooved animals as well as humans in the context of stand-up fighting. Kicks play a significant role in many forms of martial arts, such as savate, taekwondo, sikaran, karate, Pankration, Kung fu, Vovinam, kickboxing, Muay Thai, capoeira, silat, and kalaripayattu.
