Study On The Evalution Methodology Of Aging Skeletal Muscle Function In Wrinkly And Oldly

Objective:Through literature reading,expert interviews and statistical analysis,this study developed a method to evaluate the degree of skeletal muscle decline in middle-aged and elderly people in China.It provides a basis for the early evaluation of skeletal muscle decline in middle-aged and elderly people in China and for the exercise intervention in order to promote the physique and health level of middle-aged and elderly people in China.Methods:This study through the literature reading,screened in aged skeletal muscle recession evaluation methods and test indicators,selected 9 experts to conduct interviews with experts,according to pre experiment data using the statistical analysis method of evaluation index and testing method in old skeletal muscle recession.In the development of the elderly and ultimately determine the age of skeletal muscle function the degeneration of percentile score table,making the elderly aging skeletal muscle function degeneration grade standard.Results:1 The evaluation indexes after expert interview were as follows: relative limb skeletal muscle mass(RASM),upper arm muscle circumference(MAMC),grip strength,lower limb extension knee muscle group muscle force,daily pace,simple body function evaluation method(SPPB).2 The indexes of primary screen were tested by factor analysis.The evaluation indexes were as follows:relative limb skeletal muscle mass(RASM),upper arm muscle circumference(MAMC),grip strength,lower limb extension knee muscle group muscle force,daily pace.3 The absolute value of normal test results of laboratory data in each age group is less than 1,which can be regarded as approximate normal distribution,and a dial gauge is made by using standard hundred-point method.5 According to the formula: comprehensive scores = relative limb skeletal muscle mass score/arm muscle circumference(grip strength score+lower limb extensor muscle strength score)*0.5+daily pace score.Using the percentile method of grading evaluation of comprehensive scores.Cutpoint using P62,P60,P85.Less than P20 was aging skeletal muscle degenerative severe group,P20-P60 was aging skeletal muscle degenerative moderate group and P60-P85 was aging skeletal muscle function degeneration mild group.Greater than p85 is normal.Conclusions:1 The evaluation index for the wrinkly and elderly in our aging skeletal muscle function degeneration: muscle quality dimensions: relative limb skeletal muscle mass,arm muscle circumference;muscle strength dimensions: grip strength,lower limb extensor strength;the ability of physical activity: Daily pace.2 Make out suitable for wrinkly and elderly people in our country were age-related degeneration of skeletal muscle function evaluating scores table of each evaluation index.3 The laboratory measurement standards and simple standards for grading age-related skeletal muscle dysfunction in middle-aged and elderly people were proposed.
