A sport board and a shock absorption system therefor, includes a glide board used in snow and aquatic sports or a roller or skate board, a rocker platform mounted in a seesaw fashion atop the sport board, whereupon opposite ends of the rocker platform may alternately move towards and away from the sport board, and a shock absorbing cushion disposed in respective spaces formed between the forward end portions and the rearward end portions of the sport board and platform. The cushions inhibit rocking of the rocker platform, absorb impact, and create a cushion sufficient for the rider to exert extreme pressures for balance, control, and maneuvers on any given terrain conditions. As a skate board, the board is curvilinear, including a center section that is spring-like and downwardly concave opposed end sections that are upwardly concave, and roller assemblies are proximate the opposite ends or end sections. The board includes shock absorbing bumpers.
