Comparative Study On The Spike And Blocking Effects Of China Women’s Volleyball Team And Its Opponents In The 2020 Tokyo Olympic Games

The 2020 Tokyo Olympic Games was affected by the epidemic.In order to ensure the health of the participants,all parties discussed and decided to postpone the competition until 2021.In order to further analyze the situation of China women’s volleyball match in Tokyo Olympic Games,this paper makes a quantitative analysis of the spike and block effects of China women’s volleyball team and its opponents in this Olympic Games by using the methods of literature review,video observation,comparative analysis and mathematical statistics,and finds out the characteristics of China women’s volleyball team in attack and defense,as well as the advantages and disadvantages of women’s volleyball players themselves in spike and block,so as to summarize the spike and block techniques in this competition and provide data reference for the future training and competition of China volleyball team.In the volleyball match of the Olympic Games,the China women’s volleyball team lost 0-3 against Turkey and the United States,and then lost again with a fierce2-3 against Russia.After losing three games in a row,China women’s volleyball team beat their opponents 3-0 in the final matches against Italy and Argentina,but in the end,China women’s volleyball team missed the final with 3 losses and 2 wins in the group stage,which was the worst result since China women’s volleyball team participated in the Olympic Games.Based on the data analysis of spiking and blocking techniques in these five games,this paper draws the following conclusions:1.From the basic situation,there is no significant difference in age,weight and Ketole index between China team and its opponents.In terms of height,spike height and block height,China team has a significant advantage in height,while Argentine team has a low height.Through the test of significant difference,it is concluded that there is a significant difference between them,especially in block height.2.In the spike,the second position in the match between China and the Turkish and American teams was not effective,with less offensive scores and more mistakes.The spike effect of China team in the third position is relatively good.Spike at the fourth position is the most offensive point of each team,and it is also the main scoring position.China’s offensive effect at the fourth position is not much different from that of its opponents,but the blocked death rate is higher than that of its opponents.On the one hand,in the back spike,China team has less attack times and lower attack effect,which is far behind the strong teams.3.In blocking,single-player blocking is rarely used by each team.In the face of flexible fast attack,the blocking area of single-player blocking is small and the blocking effect is not good.In the face of the opponent’s tap,the China team performed relatively well in the single block.China team uses double block more,but the blocking effect is not good in the match with opponents,and there are many blocking mistakes.In the three-person block,it can be concluded that there is no obvious difference between China and the strong teams,but there are many mistakes,so China needs to make more efforts in the block.4.The Tokyo Olympic Games in 2020 was affected by the epidemic,which led to the long-term training of the team.From the 2019 Women’s Volleyball World Cup to the Tokyo Olympic Games,the China Women’s Volleyball Team has been in a state of training.Long-term monotonous and repetitive training has led to poor training results for athletes.The time between two consecutive seasons of qualifying for the Super League is short,and players have relatively few opportunities for actual combat.However,the strong teams in Europe and America are not like this.The league has a long time span,and the events are intensive,so there are many opportunities for competition and exercise.From this point of view,this is also a very important factor in the competition.
