Applied anatomy and kinesiology, the mechanism of muscular movement . Fig. 176.—The forward roll. Starting position. By practice of this simple movement one who is strong enough,as soon as he has learned the coordination of the push with thehands, the full flexion of the bodv and then its full extension, can. The forward roll. Midway. undertake the long or high dive, in which the body is launched intothe air head first by a forcible extension of the limbs, touches themat first with the hands, and completes the movement as in the GYMNASTIC MOVEMENTS 295 forward roll. The muscular action is the same but much morevigorous, the arms having to sustain more weight to protect thehead from striking too hard and the speed of the movement makingit more difficult to flex the body soon enough. The front summersault is a variation of the high dive. The gym-nast springs high into the air and then suddenly flexes his wholebody into the position it takes in the forward roll. To do this inthe air and to do it quickly enough calls for a very sudden andstrong action of the flexor muscles of trunk and limbs, beginningwith a violent downward swing of the arms. The body turnscompletely over in the air and at exactly the right time the exten-sors act and support it in normal position on the feet.
