Research On Training Effect Of Canoe Based On Special Ability Evaluation

Purpose: The 2020 Tokyo Olympic Games is coming,our country national canoeing team is in full swing preparation.This research uses the special evaluation system,combined with the special characteristics of rowing,to establish a relatively mature evaluation guarantee system,to find out the advantages and disadvantages of athletes,and to change the training plan;In order to provide reference for the selection and training of athletes in the future,it is necessary to select outstanding athletes,set up core teams,determine the points of winning cards,prepare for the Tokyo Olympic Games,and set up a database of elite athletes' special sports abilities.Methods: in this paper,14 athletes from the national rowing team were tested in December 2017,March 2018 and October 2018 by using the special ability assessment system.In the test,the power value of the dynamometer,the maximal oxygen uptake,the blood lactic acid value,the lung ventilation and other indexes were collected,and the sports ability of the key athletes was evaluated,combined with the training plan for the preparation of the training and the results of the recent competition.Through the method of statistical paired sample T-test,the change of test indexes in the stage is analyzed,and the coaches are fed back to the coaches in time,so that the coaches can fully grasp the changes of athletes' special ability.Conclusion: the ultimate goal of sports training is to achieve better results.After a winter training,the power of 10 seconds is significantly increased in the speed test(P< 0.008),the maximum ventilation P value is 0.003,the maximum ventilation capacity is 0.003,and the maximum ventilation capacity is 0.003 in the speed test of the female rowers after a winter training.The blood lactic acid P value was 0.68 and the two-minute power P value was 0.61.There was no obvious difference in the two-minute power output due to the poor improvement of glycolysis energy supply system during winter training.In terms of endurance test,the blood lactic acid P value of women rowing was 0.008;the relative oxygen uptake P value was 0.017;the maximum pulmonary ventilation P value was 0.036,and the maximum pulmonary ventilation capacity was 0.036.In terms of force test,the indexes of female rowing were P < 0.05,which proved that except for the decrease of blood lactic acid value,the other indexes were obviously higher than those of the control group(P < 0.05).In terms of results,four of the seven women rowers won the first place in the World Cup and two in the Jakarta Asian Games.After a winter training,the power P value of 90 seconds was 0.031,the P value of relative oxygen uptake was 0.038,the P value of blood lactic acid was 0.031,the power of 90 seconds was 0.031,the P value of blood lactic acid was 0.031,and the P value of blood lactic acid was 0.031.The P value of maximal lung ventilation was0.042.The P value of each index in endurance test was less than 0.05 in the male rowing through a winter training.The training level of the athletes was improved obviously.In terms of velocity measurement,the 10-second power P value of the male rowing was 0.036;the 30-second power P value was 0.028;the relative oxygen uptake P value was 0.045;the maximum pulmonary ventilation P value was 0.013,which proved that the speed of the canoe was 0.013.In terms of testing,the indexes of male rowers were P < 0.05,the value of blood lactic acid was obviously decreased,and the other indexes were obviously increased.In terms of competition results,the two athletes achieved the first place in the Jakarta Asian Games;in September 2018,in the National kayak static Water Championships,all seven of the players scored the top three in the race from different distances.The two athletes won the first place in the Asian Games in Jakarta and the first three in the National Canoe static Water Championships in September 2018.Through the special evaluation system,we have found key players,men canoe Wang *,Liu *;women canoe Sun *,in the next preparations for the Tokyo Olympic Games,will be around them to do a lot of boat work.Conclusion: After testing 14 athletes in different stages,the training plan was adjusted in winter training,the oxygen uptake of 14 athletes was improved,most athletes reached the international level,the blood lactic acid decreased after the stage training,the training plan was adjusted in winter training,the oxygen uptake wasimproved in 14 athletes,and the blood lactic acid was decreased after training.Some of the athletes won the championship in the World Cup,the Asian Games and the national competition,and the results were in line with the evaluation results.Through the establishment of special ability evaluation system,the scientific nature and pertinence of national canoeing team training are improved,and the training quality is guaranteed.
