The study of skeletal muscle weight change on female elder adults

Purpose: There are several problems after post-menopausal and higher age in the female. It may affect their physiological results, especially in the changes of their body composition. Older adults change their skeletal muscle weight when they are aging. But what differences their skeletal muscle weight change is still unknown. There is little previous research. Therefore, the purpose of this study was to investigate skeletal muscle weight change on female older adult. Methods: 48 women aged 41-80 years old were randomly selected and divided into four different age groups: 41-50 y (14 persons, abbreviated as number), 51-60 y (12), 61-70 y (12) and 71-80 y (10). All subjects' body compositions were measured. Body composition analysis was conducted using the In Body 220 body composition analyzer. Data analysis was conducted using the SPSS statistical software for Windows 15.0. Independent one-way ANOVA was used as the statistical method at a significance level (α) of.05, followed by the Scheffé's method to account for multiple comparisons. Results: Statistical analyses show that means of 4 skeletal muscle weight groups was 22.27±2.12(kg), 21.41±2.12(kg), 21.16±2.25(kg), 16.64±1.98(kg), there is significant differences in between 41-50y, 51-60y, 61-70y and 70-80 y group (Scheffé: 41-70 y>70-80 y). Conclusions: This research conclusion is that the skeletal muscle weight were similar from 41 years old to 70 years old in female older adult. But after 71 years old the skeletal muscle weight aging quickly.
