Scoring

The maximum distance between the reaching height and the jumping Height provides the score of the test. However, to get the power in foot-pound units, the above distance is multiplied by the subject body weight. But the majority of the testers routinely used directly the distance jumped irrespective of body weight as the score of the test.

CHINNING UP-

A horizontal bar is required for the chin-up or is placed at the appropriate height keeping in mind the height of the player. In this, the player grabs the horizontal bar with both hands with an overhand grip, then he is signaled to raise his body upwards until his chin appears above the bar, then he again goes back to the former position in which his Hands become straight. He tries to repeat this action as many times as he can.
