While running, the motion of your hands includes two types: oscillatory and linear motion. The back-and-forth swinging of your arms is an oscillatory motion, similar to a pendulum’s repetitive movement. Simultaneously, your hands move in a straight line, aiding in your forward movement, which is linear motion. These combined motions help maintain balance, generate momentum, and assist in propelling your body forward while running.
Motion of your hands while running – Oscillatory motion.
