What does "sankyo" refer to in Taekwondo?

Sankyo is a term that emphasizes the concept of using an opponent's energy against them, highlighting a fundamental principle in martial arts. This technique embodies the idea of redirection, allowing a practitioner to defend themselves or counterattack while minimizing their own energy expenditure. In Taekwondo and other martial arts, it represents the strategic approach to combat, where the focus is on understanding the dynamics of energy and movement in a confrontation. Utilizing an opponent's force can create opportunities for effective counters and advantage-seeking positions, making this principle vital for advanced training and application in various situations.

The other options don't accurately capture the essence of sankyo, as they focus on various aspects of Taekwondo that do not specifically relate to the strategic use of energy in combat.
