| HRV(heart rate variability)is the important mechanism of the human cardiovascular system regulation stability,reflect the autonomic nervous system activity and the quantitative evaluation of cardiac sympathetic nerve and vagus nerve tension and balance,thus determine its condition and prevention against cardiovascular disease.In this article,through different aerobic exercise plan(taichiquan,pace),to explore aerobics for overweight women aged 50 to59 HRV effect,so as to provide theoretical basis for middle-aged and old scientific fitness.Select overweight middle-aged women aged 50 to 59 48 people,eventually the number of effective for 43 people,among them in taijiquan exercise 15 people,15 people to attend his pace movement,the control group of 13 people.Tai chi group and pace for 12 weeks of exercise intervention,intervention test respectively 0 weeks,6 weeks after intervention,intervention after 12 weeks of body composition and HRV index,analysis of records.The results of the study(1)intervention after 12 weeks,his pace group of BMI,body fat percentage,fat content compared with the control group with significant difference(P < 0.05),the tai chi group of body fat percentage compared with the control group with significant difference(P < 0.05).(2)the quiet condition,12 weeks after intervention,RR index leapt group has a very significant difference,compared with before(P < 0.01);Pace set SDNN indicators have significant difference,compared with before(P < 0.05);Pace with the tai chi group RMSSD index has a very significant difference,compared with before(P < 0.01);Tai chi group LF indicators have significant difference,compared with before(P < 0.05).Tai chi group RR value compared with the control group with significant difference(P <0.05);His pace set of RR value compared with the control group has a very significantdifference(P < 0.01);Pace set SDNN value compared with the control group with significant difference(P < 0.01);Tai chi group,leapt RMSSD value compared with the control group has a very significant difference(P < 0.01).(3)within 10 min after quantitative load movement recovery,12 weeks after intervention,compared with before intervention,pace set of VLF exists significant difference(P < 0.05).Within 10 min after quantitative load exercise recovery compared with before intervention,control group LF index compared with the tai chi group,the pace has significant difference(P < 0.05);Compared to HF and leapt group controls with significant difference(P< 0.05).The research conclusion(1)12 weeks of tai chi exercise with his pace to better achieve the effect of the movement,leapt exercise on body composition slightly better than the improvement in taijiquan exercise;(2)after 12 weeks of tai chi movement with his pace HRV time domain index can improve quiet condition,strengthen the leading role of the vagus nerve,pace is better than that of taijiquan movement;(3)12 weeks aerobic exercise intervention can significantly improve the level of HRV movement intermediate frequency domain index.12 weeks for each indicator,intervention effect is better than the 6 weeks intervention effect,6 weeks before intervention effect is better than that of the experiment,that the longer the duration of aerobic exercise,the better the effect on the improvement of the body;(4)after 12 weeks of tai chi movement with his pace,movement within 10 min after quantitative load recovery HRV index is positive change,autonomic nervous activity increased,characterized by the vagus nerve activity,improve HRV resilience.His pace slightly better than tai chi group;(5)leapt campaign in improving body composition and improve HRV is superior to the taijiquan movement,his pace movement can be better as a way of aerobic exercise in midlife women. |
