Analysis Between Pre-competition State And Competitive Albiliity Of Elite Fencers

Purpose:Through Omega Wave technology system,the study aim to explore functional state of elite fencers before competition and no injury.(1)To explore the elite fencers' pre-competition functional characteristics.(2)To explore the relationship between state and competitive ability.(3)To take prediction performance model initially.The research provides a theoretical basis for the athletes training,and then,it can reduce the capital input with its rapidly and no injury.Methods:Elite fencers of Jiangsu province are participated to this program.The indicators includes:RPE,HRV,activity of vagus regulatory mechanisms,activity of sympathetic regulatory mechanisms,stress index,fatigue index,adaptation reserves index,CNS index,hormonal system index,Omega Wave index,aerobic status index,anaerobic status index,alactic status index.The testing includes:(1)Base line:Before general training for' a week.(2)Pre-competition:according to the schedule,testing was choosed the day before the competition.(3)Post-competition test:testing was choosed after the competition.Experiment data using SPSS23.0 statistics software package for data processing.Athletes' test for the different fencing,baseline and the day before the game,post-competition of the each index test value are to be repeated ANOVA,for the different level are to be independent-sample test,for the performance and pre-competition status are to be partial correlation analysis.Establish the prediction model through principle component analysis and R factor analysis.The level of significance is p<0.05,and the distinct significance is p<0.01.Results:(1)The CNS fatigue is higher than the cardiac fatigue of fencers.Besides,the rate of CNS fatigue in Epee is 57.9%,higher than the Sabre and Foil.(2)Aerobics index,epee is higher than Sabre;ATP system index,Sabre is higher than foil,p=0.03<0.05.The energy metabolism related indexes of the saber group were in the normal range,but at a lower level.The oxygen ability index of the Epee group exceeded the normal range;the index of the ATP system in the foil group was lower than that of the normal range,(3)The vagus regulatory mechanisms of Epee was significantly lower than post-competition,and CNS index was significantly higher than pre-competition.The CNS index,hormonal system index and aerobic status index were significantly higher at pre-competition(p<0.05).(4)In Epee,hormonal system index are significantly negative correlated with performance,Omega Wave index and aerobic status index are significantly positive correlated with performance.In Sabre,activity of sympathetic regulatory mechanisms and CNS index and Omega Wave are significantly negative correlated with performance,stress index and adaptation reserves index,anaerobic status index,alactic status index are significantly positive correlated with performance.In Foil,activity of vagus regulatory mechanisms and CNS index,OmegaWave are significantly negative correlated with performance.(5)Epee=35.77-4.29*factor1scores+5.69a*factor5scores.Sabre=74.58-7.68*factor1scores.Foi1=46.71+1.93*fanctor1 scores-14.53*fanctor2scores.Conclusion:(1)Fencers are more prone to CNS fatigue,besides,the incidence of Epee are higher than the Sabre and the Foil.Vagus regulatory mechanisms,hormonal system index can be used to evaluate the recory.(2)In Epee,hormonal system index,Omega Wave index and aerobic status index are closely related with performance.In Sabre,activity of sympathetic regulatory mechanisms and CNS index and Omega Wave,stress index and adaptation reserves index,anaerobic status index,alactic status index are closely related with performance.In Foil,activity of vagus regulatory mechanisms and CNS index,Omega Wave are closely related with performance.(3)The performance prediction model has the difference of sports.
