| The main research of this thesis is based on tennis competition anomalies,using the literature material method, case analysis, mathematical statistics and logical analysis.First of all, from the theoretical aspects, I discussed and analyzed the objective existence of competitive performance anomaly, abnormal nature and the concept. Then in 2014, taking four grand slam tennis men singles project for example.After determining the competitive performance evaluation and competitive anomaly judgment standard, according to different gap situation against the two sides could strength (may close this happens mainly in the semi-finals and finals’ is given priority to, large difference this situation mainly by the organizer may strength the first round and second round against the seeds and the seeds), the selection of some of the abnormal events, and try to analyze and summarize part of athletic abnormal performance in this paper. At last, draw the following conclusion:1 due to the relative closeness of training and competition of relative openness, athletes (team) competitive ability in the game sometimes can’t normal play, namely athletics performance anomaly is objective existence.2 Abnormal athletic performance:the definition of competitive performance anomalies known as competitive ability, is in the process of competition athletes will be affected by various factors, athletic ability is not normal play or display, that could power did not translate into expected the phenomena of real power. Athletic performance exception unlike "Clark phenomenon" did not defeat but competitive unusually contains athletic performance exists abnormal phenomenon.3 Athletic performance anomalies are mainly the competitive overachieving and aberrations in two.4 Athletic performance indicators are divided into two categories:competitive ability overall performance indicators and athletic performance indicators. Competitive ability constitute the technical performance indicators are divided into competitive performance index, the competitive performance tactical index, performance index, performance index. Tennis athletic performance in the overall index mainly have two points and the outcome innings. Competition and performance indicators are tennis player overall competitive performance anomaly indicators, the competitive ability constitute the performance indicators are mainly used for exceptional level analysis of the reasons.5 Men tennis tournament against both sides may be different between the different competitive performance criteria to judge abnormal:both sides may close, "sweeping" phenomenon in which disk 3-0, either party’s "first after winning" phenomenon in which 2 plate be reversed, bureau of lead appear larger fluctuation phenomenon that a disc is break 3 bureau, for her lost or 6:1; Both sides when strength is large, basically see the phenomenon of fight against longer odds.6 Abnormal main reasons are:athletic performance on the part of the event form of cyclical and before the state should adjust, tennis court, differences and technology of the wind, "restriction", "dark horse" advantage, "valentine","chocking "and injury. Relatively controllable among them has:the competitive state of cyclical and before the state adjustment, "restriction" and the psychological control (" dark horse ", "valentine", and"chocking"). |
