Sports coaches and players are interested in how training programs can be
designed to enhance performance. The order of practice potentially
facilitates learning outcomes without increasing the amount of practice.
A study was conducted to examine how different training schedules influence
throwing performance.
In this study, elementary school students threw a tennis ball at a target
laid on the floor. They threw the ball from three throwing locations at
distances of 3, 4, and 5 meters from the target. The target consisted of
the center (20 cm wide) and nine larger outer rings. They served as zones
to indicate the accuracy of the throws. If the ball is landed in the center
of the target, 100 points were given. If the ball landed in one of the
outer zones, 90, 80, 70, 60, 50, 40, 30, 20, or 10 points were recorded
accordingly. If the ball landed outside of the target, no points were
given. If the ball landed on a line separating two zones, the higher score
was awarded.
The students were assigned to one of three practice groups: Blocked,
Random, or Combined. All students were instructed to use an overarm
throwing motion to try to hit the center of the target with the ball. On
the first day of this study, they each completed a total of 81 practice
throws. Students in the Blocked group threw 27 times from one of the three
throwing locations, followed by 27 throws from the next location, and ended
practice with 27 throws from the final location. In the Random group, each
student threw 81 times in the order of throwing locations that the
researchers had specified. No more than two consecutive throws were allowed
from the same location for this group. In the Combined group, the students
started with a blocked schedule and gradually shifted to a random schedule.
On the next day, all students completed a performance test of 12 throws.
Results showed that during the practice of 81 throws, the Blocked group
performed worse than the other two groups. Performance test scores were
also analyzed. The Combined group showed the best performance among the
three groups, followed by the Random group and then by the Blocked group.
It is still uncertain if similar results can be obtained for adults in
training programs for other throwing actions, such as those seen in
bowling, baseball, and basketball. This will be addressed in following
section.
問1 What is the total score achieved by the five throws in this figure?
[ 33 ]
{1} 200 {2} 210 {3} 220 {4} 230

問2 Which of the following statements is true about the experiment? [ 34 ]
{1} Eighty-one throws were made from the same initial throwing location in
the Blocked group.
{2} The distance from the target remained unchanged during the entire
experiment for the Combined group.
{3} The set of throws from the same location involved various ways of
throwing for the Combined group.
{4} Throwing three or more times in a row from the same locations was
against the rules for the Random group.
問3 Which of the following statements is true about the results? [ 35 ]
{1} The Blocked group had the best score both during practice and on the
performance test.
{2} The Blocked group showed the worst score among the three groups on the
performance test.
{3} The Combined group showed lower accuracy than the Random group on the
performance test.
{4} The Random group had the lowest accuracy both during practice and on
the performance test.
問4 What will most likely be discussed next in this report? [ 36 ]
{1} Mental imagery training of underhand throws
{2} Observation of younger students' movements
{3} Overarm throws with eyes closed
{4} Various kinds of throwing motions
