The Barrow Motor Ability Test comprises of three items. It is
designed to test the motor ability of high school boys.
i. Standing Long Jump
It is used as a measure of explosive leg power.
The student has to stand behind the restraining line, keep
his feet several inches apart and point his toes straight ahead. He has to
swing his arms forward, extend his knees and jump forward as far as possible.
The test-retest reliability is 0.895 and the objectivity is
0.996.
Validity is 0.759. It is based on a comparison with the
composite of 29 tests.
ii. Zigzag Run
The objective of this test is to measure agility.
The student stands at a ready position at the starting
point. When the signal Ready, Go! is given he has to run the course in a
designated manner as fast as possible. He should not touch the cones throughout
the run. He has to continue running through the course three times.
The timer stops the stop watch
when he crosses the finish line at the end of the first circuit. The time
recorded to the nearest tenth of a second is the score. In case the cones are
moved during the run the trial has to be re-taken.
The area of the Test Area Floor is
30 feet by 50 feet. The equipment needed consists of a stopwatch, five traffic
cones, floor tape and score cards.
Test Validity is 0.736.
Test-re-test reliability is 0.795.
The procedure is demonstrated and
the student is allowed to jog through the course before the test.

measure the arm and shoulder girdle strength. The student has to put a 6-pound
medicine ball as far as possible.
The student is between two
restraining lines 15 feet apart. He has to hold the medicine ball in one hand
close to the point where the shoulder joins the neck. He has to thrust the ball
outward as far as possible.
During or after the put if the
student steps on or over the restraining line the trial is no scores. There are
three trials. The best of the three throws recorded to the nearest foot is the
score.
The area of the test floor is 90
feet by 25 feet.
The validity of the test is 0.736.
The reliability of the test-re-test
is 0.893. The objectivity for two scores is 0.997.
