What is the appropriate developmental sequence for running of the following descriptions of leg action?
I. The swing thigh moves forward with acceleration causing 90 degrees of maximal flexion in the knee.
II. The run is flat-footed, with minimal flight.
III. Foot contact is with the heel or the ball of the foot.
A. I, II, III
B. II, I, III
C. III, II, I
D. III, I, II
E. II, III, I
Question 2
What is the appropriate developmental sequence of running of the following descriptions of arm action?
I. Spinal rotation continues to be the prime mover of the arms.
II. Spinal rotation swings the arms bilaterally to counterbalance rotation of the pelvis and swing leg.
III. The humerus begins to drive forward and back in the sagittal plane, independent of spinal rotation. IV. The arms do not participate in the running action.
A. IV, II, I, III
B. I, II, III, IV C. II, IV, I, III
D. IV, III, II, I
E. IV, I, III, II
