Fera Nofiartika Ann Nutr Metab 2019;75(suppl 3): 285
Background: The increasing number of Indonesian elderly can be burden for the country if the health status of the elderly is low. The ability of mobility, especially walking ability, influences the quality of life of the elderly. Skeletal muscle strength in the elderly will decrease by> 50%. This decrease in muscle strength is caused by an increase in oxidative stress. Tea is one of the favorite drinks of the elderly. Green tea extract has a high antioxidant content. This study to determine the effect of giving green tea extract on muscle strength of the elderly lower extremity.
Methods: This was an experimental study using a pre-test and post-test design with control design. Sixty-one elderly from Abiyoso and Budi Luhur BPSTW who met the inclusion and exclusion criteria were divided into two groups.
Result: The intervention group was given green tea extract two capsules a day (± 168 mg catechins and 95 mg EGCG), and the control group received a placebo for 30 days. The measurement of muscle strength of the lower limb was carried out by the Timed Up and Go Test (TUG) method. At the end of the study, there was a tendency to decrease travel time in conducting the Timed Up and Go Test (TUG) in the group who received green tea extract intervention.
Conclusion: The time reduction in the intervention group was not significantly different from the control group (p > 0.05). The consumption of green tea extract has the potential to inhibit the decrease in muscle strength in the elderly.
