Astronauts found that on the Moon, movement by jumping is faster than normal walking. Why?

When walking, a person moves by means of forced oscillations of the legs as physical pendulums. Their oscillation frequency is close to the resonant frequency. Under the conditions of the Moon, where the acceleration of gravity is 6 times less than on Earth, the speed of movement decreases by about 2.5 times. Jumping range, on the contrary, increases 6 times at the same initial jump speed.
