You can perform two jumps: a straight-leg jump (knees and ankles stiff) and a normal jump (knees and ankles bent naturally). How did your ankle, knee and hip positions differ between the two jumps?
View Answer
In the straight-leg jump the ankle, knee and hip stay stiff and almost straight, so the joints hardly bend and the landing feels hard.
In the normal jump the ankle, knee and hip all bend, letting the hinge joints fold and the ball-and-socket hip flex. This bending softens the landing and absorbs the shock.
