The Analysis Of Accelerometer And GPS Index In Elite Chinese Men's Hockey Competition And Training

Purpose:The aim of this study is comparing the accelerometer index such as acceleration?deceleration?HIE and PlayerLoad^TM with the GPS index such like sprint?low speed running and average total running distance for different positions in Elite Chinese Men's Hockey Competition and Training.In order to get a thorough understanding to the Physical Characteristics and sports load in Chinese Hockey sports even the Team sports.So that distributing the reasonable training load in daily training.Methods:The 16 players of Liaoning Men's Hockey Team wore Catapult Optimeye S5 devices in 9 Chinese domestic matches and 5 training sessions.Catapult Openfield and spass processing data after the matches and training,using T test and Pearson correlation analysis.Results:Acceleration and deceleration distance accounted for about 25%of the average total running distance,low intensity of acceleration and deceleration distance accounted for about 20%of the total running distance,low intensity of acceleration and deceleration distance accounts for about 80%of the total acceleration and deceleration distance.The 2D Player Load^TM and Player Load^TMSlow account for about 60%and 30%of the total Player Load^TM respectively.The average number of HIE times and HIE times per minute of strikers are higher than that of the midfielders and defenders.There is a high correlation between average total Player Load^TM and average total running distance?r=0.854,P<0.01?.There is a moderate correlation between the Player Load^TM and the running distance per minute?r=0.730,P<0.01?.The 2D Player Load^TM was highly correlated with the average HIE frequency,and the correlation degree was higher than that of the Player Load^TM and HIE?r=0.81 and r=0.61,P<0.05?.Besides,the strikers'Player Load^TM per minute and the Player Load^TM per meter are higher than that of the midfielders and defenders?P<0.05?.The Competition overall Accelerometer and GPS monitoring indexes were all higher than the training indexes,and the differences in different positions were different.Conclusion:The micro movement capture device based on the 3d axis inertial acceleration sensor can monitor the agility demands?acceleration?deceleration?change of directions?,and the Player Load^TM can quantified the external load exactly,which Improving GPS technology can only conduct monitoring continuous running,and making up the heart rate,blood lactic acid and other internal physiological load monitoring body load uncertainty,provides accurate load control for scientific training.There is a high correlation between average total Player Load^TM and average total running distance,which illustrating Player Load^TM can effectively reflect the characteristics of continuous running related movement of the load.The 2D Player Load^TM is highly correlated with the average HIE frequency,indicating that the 2D Player Load^TM can effectively reflect the agility demands.The striker produced more explosive movements during the game.The defensive position also has explosive movements that is even more than the offensive position.It is suggested that GPS should be combined with Accelerometer to monitor matches and training,The training load should be adjusted according to the different positions of different indexes through training and competition.Corresponding Player Load^TM should be monitored in different positions,The position of the more explosive movement should be focused on monitoring its 2D PlayerLoad^TM,and the positon of more continuous running should be focused on monitoring its PlayerLoad^TM.It is necessary to pay attention to the development of the striker's explosive ability,and focus on improving the capacity of ATP-CP system and Glycolysis system,and shouldn't ignore the development of aerobic capacity.Shouldn't ignore the development of defensive position explosive ability,The emphasis should be on training the ATP-CP system to enhance the ability of accelerating and tackling.
