We have conducted practical classes on ball receiving exercises with individuals, groups and teams, including sending and receiving balls upwards and downwards the wall using two hands, sending balls to a definite target on the wall and receiving them. We did this exercises ten times, playing ten minutes each time with two minutes.
Jump served balls are usually received from below using two hands as this type of serving is difficult to receive from above because of great speed. According to the type of serving different kinds of position , movements are chosen[12].
After applying different resulting methods, in the third table we can see that the total number of balls in three sets served simply from a standing position is – 13, exactly received balls are – 13, no lost balls, efficiency is – 100%.
The total number of balls using oscillatory movement is- 21, exactly received balls are – 18, lost balls are – 3, efficiency is – 85.7%.
The total number of balls using jump serving with one or two steps is –16, exactly received balls are – 13, lost balls are – 3, efficiency is – 81.2%.
The total number of balls using jump serving with force is – 13, exactly received balls are- 9, lost balls are – 4, efficiency is – 69.2%.
The total number of balls served by the opponent team is 63, the number of balls received by our team is-53, lost balls are – 10, receiving efficiency is – 84.1%
