Analysis Of The Correlation Between Sarcopenia And Index Of Different Sports In The Elderly

[Objective]To understand and analyze the related indexes of sarcopenia anddifferent exercise in the elderly population.[Methods]Selection of 414 cases of 60?89 year old people.Among them,223 cases were female and 191 cases were male.Collect the physical examination information of the medical examiners Weight,height and waist circumference were measured and body mass index(BMI= weight/height2)and waist circumference height ratio(WHtR= waist circumference cm/height cm)were calculated.Hologic Discovrey-Wi bone densitometer was used to determine tappendicular lean mass(ALM),measured 6 meters straight normal walking speed and grip strength,calculation of ALM index(ASMI).The population of the physical examination was divided into 3 groups at the age of 10 years.The 60 year old group was 60 to 69 years old.The 70 year old group was 70 to 79 years old,and the 80 year old group was 80?89 years old.Statistics of male and female three age appendicular muscle mass(ALM),limb muscle index(ASMI= limbs muscle mass/height 2),6 meters straight normal walking speed and grip strength.Inquire about the relevant information with the standard questionnaire,according to the exercise mode and time.Each age group was divided into 3 groups:non exercise,aerobic,resistance groups.Statistics of the 3 groups in age,weight,height,BMI,WHtR,limb muscle index(ASMI),6 meters straight normal walking speed and grip strength.[Results]The 80 year old group.of tappendicular lean mass(ALM),ALM index(ASMI),6 meters walking speed and grip strength and sex 60 years old group 70 years old group was significantly decreased,decreased with aging.Among the 414 cases of physical examination,there were 71 cases of sarcopenia,the prevalence rate was 17.1%,the male prevalence rate was 19.9%,and the female prevalence rate was 14.8%.Exercise can improve the waist circumference height ratio of the elderly.Resistance exercise is more effective than aerobic exercise to improve the limbs muscle index and grip strength of the elderly.As the age increases,aerobic exercise can also improve the muscle index and grip strength of the elderly(P<0.05).But in improving pace,resistance exercise and aerobic exercise had no significant difference(P>0.05).[Conclusion]There is an obvious aging trend in the related indexes of myoculsis,Resistance exercise can reduce the incidence of sarcopenia compared with aerobic exercise,It can delay the decrease of muscle weight and muscle strength.
