Abstract: A device (1) for performing jumps by successive leaps, includes a tubular body (2) which is provided at one of its ends, referred to as the “lower” end, with footrest struts (3, 4); a handlebar (8) equipped with grips (81, 82) which is integral with the other end, referred to as the “upper” end, of the body; an impact shaft (5) is adapted to slide inside the body (2) and at least part of which is capable of being deployed in the extension of the lower end of the body; and elements (14) for returning the shaft (5) elastically to an extreme deployed position. The device includes elements (9) for braking the impact shaft (5) in relation to the body (2) and elements (83, 84), which are disposed on the handlebar (8), for manually controlling the braking elements(9).
