| Objective:This study uses "Shanxi province2010national physique monitoring data", the aged40-69years old in11cities in Shanxi Province as the research object, to explore, study of gripstrength in the process of aging changes in characteristics and individual health condition,living habits and exercise are the factors of correlation. Through the study on the variationcharacteristics and its confirmation grip strength factors of relevance, as the physical fitnesstest the elderly effective basis, to achieve the early prevention of diseases, to improve thequality of life of purpose.Method:literature, a comprehensive understanding of factors at home and abroad I grip strengthin older people change characteristic and its influence; using stratified cluster randomsampling method, choice of residence and place of residence in11cities in Shanxi Province,age40-69years old people as the object of study; questionnaire survey of the elderly, thegeneral characteristics and daily life analysis collection and statistics; reference to "thenational physical fitness evaluation standard manual (elderly people)" the selection of testforce.Result.1.Correlation degree of grip strength and age: in this study, aged40to69years old in40to44years old, with the average power of people,35.5kg, between50and54years old have asignificant decrease, in65to69years old of average strength reaches a minimum value,27.2kg, grip strength along with the age growth, the overall level of decreased, and thedecreased dramatically, to60to69years of age, decreased relatively stable.2.Correlation of2grip age-related changes in the urban and rural categories: the studyspeculated that, in rural than urban elderly grip, the mean difference of3.33kg, the differenceswere significant, P<0.01. Urban population and rural population in the physical quality due to different living environment and a different way of life and showed significant difference.3.Correlation degree of grip strength change with age and physical exercise: grip strengthin regularly participate in exercise group and not to participate in the exercise group hadobvious difference, the average grip strength is1.65kg, the differences were significant,P<0.01. Some other related studies, scalability, flexibility exercise can effectively promote theelderly muscle.4.Correlation degree of grip strength changes with age and body weight: the relationshipbetween the grip level was positively correlated with BMI greater linear, body mass index,grip strength of the higher level. The study concluded, the body is light grip age group andobese group was10.8kg, the difference is significant, but the weight of normal age group togrip the highest body mass index. Grip BMI grip BMI underweight age group was higher thanin obese subjects.Conclusion:1.Grip levels decreased with age, reflecting the expansion of human arm muscles andligaments decreases with the body’s natural aging, grip strength in older people in Shanxiprovince overall in ground level;2.The difference between2gender and urban and rural categories reflect the same agegroups and different levels of grip, grip strength of the male was higher than female, ruralpopulation is higher than that of urban grip levels of grip;3.There is a significant gap between the3often participate in sports in the elderly andhas never participated in the movement of the elderly in the grip level, embodies theappropriate exercise helps to improve grip strength level;4.Grip strength of4obese subjects age group is higher than that of partial light grip, andthe grip body mass index weight normal age group is the highest; simple correlation analysisshowed the negative correlation between BMI index and grip strength, there needs to befurther studied how the correlation between BMI index and grip strength were further;5.Age, gender of grip and negatively correlated positively with physical exercise, urbanand rural, education level, relative to other related researches, the conclusions of this study can be used as reference. |
