Solution

When an athlete is landing from a height on a hard floor, his feet immediately come to rest which causes a very large force to be exerted on his feet by the floor.
In case he lands on sand, for some distance, his feet push the sand hence the time period in which the feet come to a halt increases.
Consequently, he is saved from getting hurt as the force exerted on his feet decreases.
