Application Of Control Stroke Frequency In Rowing Training And Competition

This paper analyses four boat on Shandong women's rowing team for the Thirteenth National Games as the research object,observe four different boats during the competition and training support for different frequency transformation training score changes and physiological characteristics,the control model is established according to the years of preparation and training experience of the different branches of the boat paddle frequency change training and athletic performance,to a good reference for training and competition,and steps to improve players physicalfunctions,realize sports performance leap.Provide a theoretical basis for future data and control of rowing training more scientific training methods.A new control paddle frequency training from 2000 M Some results can be seen before,after the error is very small in the basic principle which is consistent with the kinetic energy of a uniform motion of constant velocity,more conducive to play sports performance.Research on stroke frequency transformation training has important theoretical and practical significance in competition and training.This study used the method of literature,expert interviews,empirical research method and mathematical statistics method,in Shandong for the Thirteenth National Games women's four different rowing in the three months before the training process,the research achievements and different frequency transformation before and after the first half of the results of the analysis,draw the following conclusions:1.to the Shandong women's rowing team preparing for the Thirteenth National Games as the research object,to change the stroke frequency of the experimental variable,the body with lactic acid oar frequency brought by different changes as the dependent variable,according to the experimental results,experimental study that the selected index is reasonable.2.to observe the performance changes and physiological characteristics of different rowing frequency training in four different rowing competitions during preparation and training.The results show that the change of lactic acid value can reflect the results of athletes' sports,and the results of high pitch frequency training are the bestCan control3.paddle frequency training from 2000 M section results showed that the first course,the error is very small in this with such uniform motion dynamics principle of a constant speed,is conducive to play sports performance.4.paddle frequency control training energy athletes ability training can achieve effective control of rowing training process5.the formulation of the pitch frequency control model must be based on the long-term training and data accumulation of the players6.paddle frequency control training should be implemented in different stages,so as to gradually improve the athletes' special performance7.the use of physiological lactic acid function to monitor the physical training situation,grasp the athletes functional level,energy metabolism,training load intensity,can prevent excessive training and promote the recovery process of sports injuries.And corresponding suggestions are put forward:1.in the training process,to make reasonable collocation of stroke frequency and stroke distance combined practice,the fixed frequency,increasing row spacing can be used in practice.The fixed stroke length,the increase of tempo training.And measured the speed of the ship,find the oar frequency for this team and draw from the collocation,at the fastest speed.2.can refer to two stroke rhythm characteristics,combined with the technical characteristics of rowing team,to find a suitable team paddling rhythm,and practice,master,which is the basis for the team oarsmanship stability,keep the speed stable.3.a complete exercise cycle,pull back stage or stage award time and time allocation is an important factor to improve the performance of dynamometer.Sufficient time to prepare to award for the next cycle,including joint return to quasi pressure by teaching attitude,change the initial length of muscle,muscle stretch angle so,these factors can influence the pressure ring muscle work.4.the training process not excessive pursuit of high frequency low frequency oar training helps to increase the angle of joint activities and increase the recovery stage for motion cycle,can improve the paddle frequency,thereby increasing the training effect.5.under the condition of limited paddle frequency,the distance of each paddle directly affects dynamometer performance.When using dynamometer,it is necessary to increase the prize distance as much as possible in each stroke period according to the suitable oar frequencyResults.6.coordinated development of each joint,should not only focus on the development of individual joints muscle,should be balanced development of the whole body ring day together to complete the action.In that row award special meat training at the same time,can not ignore the coordination training,strengthen coordination exercises help to improve the Planning Award for technical movements,to improve athletic performance.7.before exercise should formulate a physical distribution scheme,reasonable distribution of physical fitness is helpful to improve the performance.The oars should be kept uniform in the first half,reduce the speed change frequently caused by energy consumption,the lactic acid value can quickly disappear,motion recovery.So after half of the sprint stage will have plenty physical fitness.
