| Purposes:Students’ physical fitness is the national department of education has been concerned about one of the major problems, in the roof of the knowledge economy of today, if a student is not on the field, has lost the "capital", then take what others and spell it? From the word "strength" is put forward in 2013, the author start from students exercise intensity, combined with its team of wushu exercise intensity,feedback through the experiment of biological information, observation and by comparing students heart rate variability of the difference between different projects,purpose are interventions for wushu exercise intensity, exercise intensity to improve students’ extracurricular sports activities, to improve students’ the vagus nerve function, improve cardiopulmonary function so as to improve students’ physical fitness, and to explore whether wushu exercise is suitable for students to exercise intensity, as well as martial arts and strength in the process of exploring the relation of provides the certain reference value.Methods:This article focus on using experimental research method, selection of yangpu experimental school students of preparatory class 28, professor of wushu exercise intensity, corrective action, training until complete fluidity experiment for students; Watching the movement of practicing calisthenics and strength wushu exercise intensity, analyzing and comparing two projects the influence of heart rate variability study for students.Results:at present, the heart rate variability as a used to reflect the physiological state of autonomic nervous function of a physiological quantitative indicators, has got broad application in many areas, so the results should also be linear indicators of heart rate variability(time domain and frequency domain indicators). Test through the experiment, the experiment after broadcasting gymnastics(group a) were students and strength of wushu exercise(group b) had the students nonlinear stability index,coordination index, evaluation index scores are higher than before the experiment;Group(b) a student linear time-domain indicators were all normal, sinus cardiac interphase(NN) standard deviation(SDNN), the phase difference between adjacent RR RMS, and used to reflect the size of the rapid changes in composition(RMSSD),the number of period > 50 ms difference between adjacent RR of the percentage of the total number of heartbeat(PNN50) test results is lower than before the trial, linear index, frequency domain index reflect the total activity of autonomic nervous system(TP), total power very low frequency(VLF) power within the scope of, reflect the activity of the sympathetic nerve is low frequency within the scope of the power(LF),which can reflect the vagus nerve activity within the scope of the high frequency(HF)power, and reflect the sympathetic nerve and parasympathetic nerve activity of the ratio of the equilibrium condition of LF and HF(LF/HF) and relative magnitude of the response of the sympathetic nervous activity of standardized LF power(LF norm)and relative magnitude of the response of the vagus nerve activity of HF power(HF norm) after the test results also show that the experiment is slightly lower than before the experiment.Conclusions:nonlinear index of the experimental results show that, through the strength of wushu exercise intervention, to improve students’ ability in self adjustingof bad mood; Not only that, wushu exercise intensity exercise also improves the parasympathetic nerve activity for middle school students, effectively improve the balance of the sympathetic nerve and parasympathetic nerve, also exercise the function of cardiac autonomic nervous regulation rule, the influence of it to a certain extent, reduce the acquired risk of arrhythmia and myocardial infarction. Wushu exercise intensity and yangpu experimental school’s broadcasting gymnastics also effective to improve the sensitivity of the autonomic nervous sympathetic nerve, but from the perspective of the biological information of experimental data feedback,intensity of wushu exercise group reflect the activity of sympathetic nerve and parasympathetic nerve balance is more good. |
