Until now, strengthening muscular groups of lower limbs, focusing on musculus quadriceps femoris was done as a kinematic method of preventing a fall. In recent years, the role of the greater psoas muscle (a muscle connecting the thighbone with the backbone) in the body trunk is starting to garner attention. Though the changes of the musculus quadriceps femoris was one of the indexes of preventing long time turnover, this research is to compare changes of the greater psoas muscle to changes of the musculus quadriceps femoris by measuring those who are aging. The number of women's bone fractures by falling is approximately 2.5 times greater than that of men's, and is one of the big causes of needing care. Therefore, the muscle cross-section of greater psoas muscle and musculus quadriceps femoris were measured by MRI in this research focusing on women, from ages 20 to 70, with each age class containing 35 people, for a total of 210. As a result, the difference of the atrophia degree in greater psoas muscle was recognized from age of 40, and it became clear that it will be the biggest in the age of 70. The difference of the atrophia degree in musculus quadriceps femoris was not recognized until the age of 40, and it was recognized from age of 50 to 70. In comparison of the greater psoas muscle and musculus quadriceps femoris, the difference was recognized in the age group between 40 to 70. It was indicated that not only the strengthening of the lower limb muscular group, but the strengthening of greater psoas muscle is also important in kinematic method of preventing falls.
