성인의 영양상태가 신체기능에 미치는 영향 : 단백질 섭취량과 팔 부분을 중심으로

Abstract

In this study, investigation was conducted on the amount of average daily protein intake and nutrition adequacy ratio among nutritional intakes, for 33 middle-old aged females, and the relationship between protein intake and functions in arms was examined through evaluation of arm muscles. For the subjects, the average daily protein adequacy ratio was surveyed, and they were divided into 3 groups (low met group, met group, and excessively met group), for which upper and lower arm circumferences, and the thickness of Biceps brachii and Triceps brachii were measured. In addition, the arm power was measured to understand the relationship with the protein adequacy ratio between the groups. As a result, even if the daily protein adequacy ratio in the low met group might be 2 times or more lower than that of the excessively met group, its lower arm circumferences and muscle thickness of Biceps brachii were higher compared to the excessively met group (p＜.05), and its muscle thickness of Triceps brachii appeared higher than even that of the met group (p＜.05). In the meantime, the grip strength also showed a higher value in the low met group, compared to the met and excessively met groups. What we could see through the results of this study is that it is necessary to examine in detail the presence of the ingredients - e.g., vegetable proteins, animal proteins, etc. - of foods ingested by the subjects in their daily lives. Furthermore, it will also be necessary to secure the reliability of the study by obtaining additional data on cities and males.
