Economy of movement refers to the concept of using the minimum amount of physical effort or motion required to accomplish a task or movement. It is often used in the context of sports, dance, and other physical activities where efficiency and precision are important.
In sports, for example, economy of movement is critical to achieving maximum performance while minimizing the risk of injury. Athletes are trained to use the minimum amount of effort required to make a movement, such as a golf swing or a tennis serve, in order to conserve energy and maintain accuracy.
In Systema, economy of movement is also important, as it helps students to conserve energy and move with precision, speed and power. Martial artists are trained to make their movements as efficient as possible, using only the muscles and movements necessary to achieve a desired effect.
