The Effect Of Mountaineering On Heart Rate Variability In Adults

ObjectiveThis study is analyzing the mountaineering training’s effects on HRV and HR ofadults in different age and gender by comparing the difference of heart rate variabilityafter16weeks of mountaineering exercise, and try to find out what the role onpromoting cardiovascular health it plays, then the results can be used to provide ascientific basis and theory reference for the application of heart rate variation in thepublic fitness exercises.MethodsThe94subjects are adults in20-59from Beijing，who are divided into young malegroup， young female group， middle-aged male and middle-aged female groupsaccording to age and gender. All subjects were trained in mountaineering for16weeks.The electro cardio signals of all subjects are collected before and after the exerciseintervention with PolarRS800cx, then we can extract the heart rate variation raw datawith PolarProTrainer5.0. Finally the SPSS for windows20.0is used for a series ofanalysis, including the single sample K-S inspection, pared-samples T test, correlationanalysis.Conclusion:1. Through16weeks mountaineering exercise, it can improvehealthadults’heartrate variability, improve the ability of the regulation of autonomic nervous system onthe heart, reduce the resting sympathetic nervous activity, improve the parasympatheticnerve activity, to improve the protection of autonomic nervous system on thecardiovascular system, reduce the risk of cardiovascular events. Through16weeksmountaineering exercise, it can reduce the resting heart rate.2.16weeks mountaineering exercise on improving males’ heart autonomicnervous regulation ability is more significant than females.3. Mountaineering exercise prompted the sympathetic-parasympathetic balanceaptitude parasympathetic dominant direction. Including reduced sympathetic activityand increased parasympathetic activity. Greater influence on the youth of thesympathetic nerve activity than the middle age, the effect on the sympathetic nervous activity between males and females is undifferentiated. The effect on theparasympathetic nerve activity decreases with aging, the impact on the males may bemore than females.4. The resting heart rate variability of healthy adults in20-59years old changeswith aging, males and females’ autonomic nervous regulation ability andparasympathetic activity decline with aging, but males decrease significantly thanfemales.
