碩士 / 靜宜大學 / 食品營養學系 / 107 / Studies showed that middle-aged and elderly had lower muscle strength and physical performance as the age increased. Dairy is rich in high-quality protein which can increase the strength of muscles. This study was to investigate whether the muscle strength of middle-aged and elderly varied by the amount of dairy intake. The recruitment targets were for people over 40 years old in the coast area of Taichung city, including Dadu, Shalu, Longjing, Wuci and Cingshuei. Exclusions were cognitive impairment, use of assistive devices, neurological diseases, musculoskeletal diseases, trauma or surgery in the hands or limbs in the past three months, inability to measure physical performance, and inability to ingest dairy. Dairy intake, muscle strength and physical performance by structured questionnaire, grip strength measurement, physical fitness and short physical performance battery (SPPB) were observed. The structured questionnaire collected basic demographics, exercise frequency, dairy knowledge, attitude, and weekly dairy intake frequency. Grip strength were measured with a Jamar gauge. Physical fitness according to "National Fitness Testing Implementation Measures" of the Ministry of Education. The SPPB consists of three parts balance ability, walking speed and chair sitting. The data was analyzed with SPSS 20 version of its chi-square test, independent sample t-test, Pearson product correlation, Spearman correlation. A total of 75 subjects were recruited. The results showed that all subjects did not reach the guideline for daily dairy intake. There was a positive correlation between dairy knowledge, attitude and behavior (p<0.05), and age was negatively correlated with physical performance. The daily dairy intake of 61 female subjects was positively correlated with hand grip strength, upper and lower limb muscle strength and muscular endurance, balance ability and SPPB performance (p<0.05). There was highly positive correlation (p<0.001) among grip strength, physical fitness, and SPPB performance. Therefore, the daily dairy intake of female has a positive relationship with the grip strength, the muscle strength and muscle endurance of the upper and lower limbs, the balance ability and the performance of SPPB. It is hope that the more community promotion of the importance of dairy intake and muscle strength may reduce the occurrence of sarcopenia.
