Results and analysis
Analysis of scores.According to the Figure 1 it can found that the scores is increasing along with the increase of the number of round in the Small levels of the project .The first 3 turns' average score is separately 6.25 points, 7.7 points, 9 points, this suggests that athletes' offense are often more conservative in the early stages of the race, in order to tentatively punches to know the other side's technique features, thus the first round scores are less than the other round.With the competition goes further, athletes have further understanding of opponent's the match against method and technical features, they gradually attack are also active up, and the corresponding score has also increased.From the data we can see that the highest stage of score is at the third round.It is because that each round shows the scores of each athlete, so both players exert their effort in the final round.The behind athletes want to reverse this situation and the leading player wants to keep the leading edge, thus resulting in higher score.The minimum average score of the middle level of the competition appeared in the first round and the big level's is in the second round.According to the characteristics, we should enhance the athletes scoring consciousness so strengthen their grasp of the ability that make every turn has the ability to keep advantage.Average 18.7:45.2 15:26.2 28.5:34 17.5:23.7 5.2:13.2 12.5:17 14:21 5. Average 25.5:22.5 25.5:25.5 25.5:19 5.5:7.5 5.5:7 6:13.5 17.5:9.512:13.5

Analysis of the boxing frequency
The balance of attack and defense for all against sports are very important, the boxing is not a exception.A good boxer must be "the omnipotence soldier" and at the same time to be "the commando", that means, a good boxing athletes need to have the ability of using various techniques, and also have an outstanding techniques.Table 1 can be founded that the Left swing is most frequently utilized in the light level project, left straight boxing is followed, and combined boxing and the left hook boxing is the lowest.Middle level most frequently utilized the Left swing, right straight boxing is followed, right hook and left hook boxing is the lowest.This is because lift hand boxing faster than right hand, so light and middle level boxers are good at left hand boxing.
Large level most frequently utilized the right straight boxing, left straight boxing is followed, right hook and left hook boxing is the lowest., this is because the right hand boxing strength bigger than left, and Large level athletes move slower, great strength.It is the situation in all of three levels that the left hook boxing is the lowest frequent utilization.Their ability of attack and defense will become more diverse if utilize more of the fist in the match.
Analysis of the frequency of using various boxing.Comparative anglicizing boxing times of boxing champion and silver medal winner can tell what the players' playing style, custom technology, while the boxing times also has a close relationship with the players level.We can analysis from table 2 that the light level of champion in boxing using frequency averaged only 2 items more than Silver Medal Winner; middle level champions in 4, 5 items more than runner-up; and large level champions had 5 up to, which reflected that as the weight increases, the fierce competition is also increasing along.The majority of the light level champion are flexible style (also called "pirates style" which is giving a fisticuff and escaping instantly) one.It needs to have plenty of strength to do guarantees.The champion and Silver Medal Winner of Middle and large Level in using various boxing getting more closer, the strength getting more weaker as the weight increasing, and the" Standing on the Stake " are using more.Utilizing more flexibility in the changing pace of the game can improve achievement if the players of Middle and large levels have enough physical power as the guarantee.Boxer utilizes variety of fist position for different purpose in the match.Fist attack method is to get score directly.Fake action is to confuse the opponent.We can cite the conception of effective punch when evaluate the effect of using varies of fist.Effective punch is able to hit opponent or successfully block attacking opponent boxing.Certainly, as the rule change, the Effective punch scored judgments are also changed .Effective punch is not the very fist which can get score every time.Whether the fist can get score rest with two aspects: the score site and enough strength to make the opponent have a displacement, so, sometimes not directly scoring boxing is effective punch.Comparison analysis the amount of fists and Effective punch can found that boxing effect has some of the practical significance to analysis completion.From table 2 we can found that light level average rate about various Effective punch is 9.35%, the highest is counter about 15.4%, the lowest is left hook about 2.7%; middle level average rate about various Effective punch is 8.11%, the highest is right hook about 18.2%, the lowest is right straight about 2.2%; large level average rate about various Effective punch is 13.2%, the highest is double hiting about 15.4%, the lowest is right straight about 2.7%.
