| Research Abstract |
The prevalence of sarcopenia was 22.1% in community-dwelling elderly women. The comparison of several variables between the sarcopenic and normal group shows that sarcopenic women had significantly lower calf girth, bone mineral density, BMI, and muscle mass, and were older. Additionally, sarcopenic women had a higher history of osteoporosis, falls, and fractures rates compared with normal subjects. To evaluate the effectiveness of exercise and amino acid supplementation in enhancing muscle mass and strength in community-dwelling elderly sarcopenic women. One hundred fifty-five women aged 75 and older were defined as sarcopenic and randomly assigned to one of four groups : exercise and amino acid supplementation (exercise + AAS; n = 38), exercise (n = 39), amino acid supplementation (AAS; n = 39), or health education (HE; n = 39). The exercise group attended a 60-minute comprehensive training program twice a week, and the AAS group ingested 3 g of a leucine-rich essential amino acid mi

xture twice a day for 3 months. Body composition was determined using bioelectrical impedance analysis. Data from interviews and functional fitness parameters such as muscle strength and walking ability were collected at baseline and after the 3-month intervention. A significant group × time interaction was seen in leg muscle mass (P = .007), usual walking speed (P = .007), and knee extension strength (P = .017). The within-group analysis showed that walking speed significantly increased in all three intervention groups, leg muscle mass in the exercise + AAS and exercise groups, and knee extension strength only in the exercise + AAS group (9.3% increase, P = .010). The odds ratio for leg muscle mass and knee extension strength improvement was more than four times as great in the exercise + AAS group (odds ratio = 4.89, 95% confidence interval = 1.89-11.27) as in the HE group. The data suggest that exercise and AAS together may be effective in enhancing not only muscle strength, but also combined variables of muscle mass and walking speed and of muscle mass and strength in sarcopenic women.
