The present invention relates to a board unit for a jumping exercise, and to a shock-absorbing leg for same. The board unit for a jumping exercise according to the present invention comprises: a main board having a wall that protrudes upwards along the entirety of the rim of a flat base panel; an inner plate which covers the base panel of the main board, and which has a tightening rib tightly coupled to the inner surface of the wall of the main body, and which has a reinforcing rib formed at the inner lower surface thereof; and an upper plate which is arranged on the inner plate, and made of a flexible material that is soft to the touch. The shock-absorbing leg for a jumping exercise has a hollow body and a pair of joint protrusions formed at the top of the main body and opposite each other, wherein said hollow body has a corrugated first shock-absorbing portion which is flexible and has a relatively lower strength, and a second shock-absorbing portion which contacts the first shock-absorbing portion and which has a strength greater than that of the first shock-absorbing portion and which has elastic restoring force. The main board, the inner plate, and selectively the upper plate of the board unit can be assembled in a one-touch fashion, thereby enabling easy assembly. The upper plate can be assembled in a variety of methods to produce a variety of designs to suit the taste of the user, and the double shock-absorbing structure of the shock-absorbing leg of the present invention can effectively absorb strong or weak shocks, thus enabling an increase in the number of users. |
