Spring Shock Absorption

The spring shock absorption is definitely higher than the rubber shock absorption cost, but the shock absorption effect is much better than the rubber mat, and there is a clear difference. However, in some shock absorber designs of the treadmill, rubber cushions are also retained. The effect of the spring shock absorption is obviously improved, but the spring shock absorber has a resilience, because the running board receives the impact when landing. It will inevitably lead to the collapse of the spring, and there will be a rebound force when the spring reaches the collapse limit, so the spring shock absorption is too soft, which means that the rebound force is higher and not good.
