It was suggested that increasing the effectiveness of the reception attack in both the 1st tempo attack and the 2nd tempo attack during the reception attack phase would approach the acquisition of the set. Furthermore, it is presumed that the 1st tempo attack increased the number of runs due to the block being blocked, and the 2nd tempo attack affected the increase in the number of runs due to mistakes, which had an effect on the win / loss and gain / loss set. Regarding the relationship between the 1st tempo attack and the 2nd tempo attack, increasing the blocking rate of the 1st tempo attack makes it difficult for the setter to use the 1st tempo attack, and the opponent's blocker increases the ratio of marks to the 2nd tempo attack. It became clear that this was a factor that reduced the decision rate and effectiveness of the 2nd tempo attack. It became clear that the decision on the 1st tempo attack is related to the number of participants in the attack, the reaction status of the opponent's middle blocker, and the number of opponent's blocks. Since the 1st tempo attack includes the elements of the skill of the setter, the setter must acquire the skills to perform the 1st tempo attack accurately, and the attacker must acquire the skills to prevent the blocked. In addition, even if the reception is a B pass, it is possible to use a 1st tempo attack and always make an attack with four people to create a situation that is numerically superior to the opponent's block, and it will be close to victory.
