Quantitative Analysis And Study Of Laws Of International Women's High-level Volleyball Competitive Process

In this thesis, the study of laws of international women's high- level volleyball competitive process is conducted by way of quantitative analysis under the theory of basic competitive unit process of net-secluded competitive item groups. After deep exploration and analysis of many women's high-level volleyball competitive processes, the essential characteristics and laws of them are summarized by the writer. It not only provides theoretical basis for the organization of training and competition, but has relatively high-level value in science as well as feasibility in practice.In this thesis, video statistical analysis of many international women's high level volleyball matches has been conducted through several scientific methods including literature review, experts reviews and mathematic statistics. The following conclusions are drawn after the exploration of the manipulating model of the basic unit competitive process:1. The theoretical study of volleyball competitive process. It systematically depicts the organizing construction of the basic competitive unit process and its stage characteristics; obtains the multi-stage construction theory of the basic competitive unit process of volleyball and enriches the theoretical research methods of volley competitive system.2. The distributing characteristics of the number of stages of the women's high-level volleyball's essential competitive process are: the distributing form of the competitive process is positive skewness (leftside); the peak value is the third stage, namely, first attack , and it has prominent status in the competitive process ; the rivalry of both sides mainly takes place from stage one to stage five, that is: service→first attack→the first defense attack on the side of service→the first defense attack on the side of receiving→the original period of rivalry and they construct the main process of a match.3. The laws of getting and losing scores in the fundamental competitive unit process of women's high level volleyball are as follows: both sides focus on the first attack as well as the first defense attack on the side of service and this is the main process of scoring; there is major discrepancy between the constructing rates of general scoring during service tactics system and service reception tactics system , in other words, that the general scores of service reception system are higher than those of the service system results from the higher score rate of service and attack. However, no obvious discrepancy appears if the cause of the first attack is excluded.4. The winning laws of the fundamental competitive unit process of women's high-level volleyball are:the match will be won by the side whose competence of scoring during process of service, the first attack and the first defense attack is superior to the other one. In other words, the key factors of winning the game lie in the three stages: service, the first attack and the first defense attack.5. The tactics -using characteristics of the fundamental competitive unit process of women's high—level volleyball are: it falls into common tactics systems when the using rate of spike reception as well as attack and service reception service as well as attack reaches to fifty percent and thirty four percent respectively. However, it falls into non-common tactics systems if the using rate of block ball-return as well as attack and pass reception as well as attack is nine percent and seven percent respectively. This indicates that defense attack(spike reception attack) has the most prominent tactics status and it, together with first attack construct the main tactics body of competitive process. There is remarkable discrepancy between the distribution of all kinds ways of ball passing in the process of fundamental competitive unit process in statistics and ways of ball passing starts to change from the third stage. The main way of ball passing is spike on the every stage. Drop is the second way of ball passing in the third stage; while, the sceond way of ball passing in the forth,fifth and the following processes are block ball–returning.
