摘要或動機

Table tennis the fastest ball sport in the world has become so fast that rallies have become\r
very short. My investigation this year is a further study into slowing the game down. Last\r
year I studied the effects the newly introduced 2mm larger ball had on the game. I\r
concluded an average increase in rally length from 2.93 to 3.47 balls per rally passing the\r
net. Although a 16% increase sounds large, it was an average of less than 1 ball per rally\r
difference. I came up with another way to slow the game down my aim was to find out if\r
increasing a table tennis net height will decrease spin, speed and increase control i.e. rally\r
length and to find out what percentage extent each height level has on these factors. I\r
wanted to be able to present a finding as to the optimum net height for the percentage\r
increase in rally length that is desired.
