Quadriceps and Hamstring Muscle Strength in Elderly based on Lifestyle
Abstract: Studies have shown
that muscle strength will decline with aging and inactivity, with 1% to 3% loss
of muscle strength each day. Nevertheless, different lifestyles have different
effect on muscle strength. This study was conducted to analyze the differences
in quadriceps and hamstring muscle strength in elderly from 60–79 years olds
according to lifestyle.
Methods: A cross-sectional study was conducted from September to November
2015. The subjects were 31 older persons from community who voluntarily
participated the research procedure and were divided into 2 groups, active
group and sedentary group according to International Physical Activity
Questionnaire (IPAQ). Quadriceps and hamstring muscle strengths were measured
using the push and pull dynamometer. The collected data were analyzed using the
Wilcoxon rank sum test and the unpaired t-test.
Results: This study discovered that the mean difference in hamstring
muscle strength was 6.09 ± 0.70, p< 0.001; median difference in Quadriceps
muscle strength was 5.00 (13.00, 6.50), p<0.001.
Conclusions: There is a higher Quadriceps and Hamstring muscle strength
in elderly active lifestyle compared to elderly sedentary lifestyle.
