Step (second) Phase of the Triple Jump
The second(step) phase of the triple jump begins as the take-off foot returns to the ground. The take-off leg is fully extended with the drive leg thigh just below parallel to the ground. As the athlete leaves the ground, the take-off leg stays extended behind the center of gravity with the calf held approximately parallel to the ground through mid-flight. At the same time, the opposite leg drives to waist level where it remains through mid-flight of the Step phase. The angle of the knee joint should be no greater than 90 degrees. As the athlete begins to descend, the drive leg extends with a flexed ankle and snaps downward for a quick transition into the third phase. During the Step phase, the athlete is concentrating on riding the step as long as possible. This is usually the weakest of the Triple Jump phases and requires the most practice and coaching.
