Exam 12: Fundamental Locomotion Skills of Childhood

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.

Skipping is performed with an uneven rhythmical pattern.

Which of the following is NOT a distinctive feature of early attempts at walking?

The developmental sequence for the leg action component of the standing long jump is

The mean age of independent walking is 9 months.

Research has confirmed that independent walking gait is initially altered when an external load (backpack) exceeds what percent of the child's body weight?

According to data about the vertical jump collected by Isaacs (2000), children of all ages jump higher when which type of vertical jump is employed?

Within the arm action component for the takeoff phase of the standing long jump (component approach), a child exhibiting "arm winging" would be at a development level of Step 2.

What do the following sentences refer to : -A motor skill best described as consisting of an uneven rhythmical pattern.

In mature running, the heel of the recovery leg should never make contact with the buttock.

Infant readiness to begin running is characterized by

The most effective angle of takeoff in horizontal jumping is 35 degrees.

The most difficult motor pattern for children to attain is the

What do the following sentences refer to : -During mature running, the performer should flex the elbows to approximately what degree?

According to research by Isaacs and colleagues (2002) on vertical jump performance, children who performed a countermovement jumped higher than children who did not.

What do the following sentences refer to : -A gallop performed in a sideward direction.

What do the following sentences refer to : -According to research, backpacks should not exceed what percent of body weight?

Boys and girls will generally start to skip between 6 and 7 years of age.

According to research on gender differences in motor skill performance, the one skill in which girls outperform boys is

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.
