the effect of adding vivifrail© exercises to conventional exercises on quadriceps muscle strength and endurance in elderly people with frailty syndrome at surabaya nursing homes

Vivifrail© training can become an alternative comprehensive training program to treat frailty syndrome (sf) in indonesia. fourty elderly people with frailty syndrome (sf) subject this study. subjects were divided into the intervention and control groups, each consisting of 20 elderly people. both groups were required to participate in conventional exercises programmed by the nursing home 5-7x/week for ±15 minutes. the outcomes assessed were quadriceps muscle strength and endurance by measuring the digital dynamometer test (dd) and 30-second chair stand test (30cst) at baseline (pre-test) and after four weeks of intervention (post-test). the results showed significant differences in quadriceps muscle strength and endurance in the intervention group (right dd test p=0.001; left dd test p=0.001 and 30cst p=0.001). in the control group, there were also significant differences in quadriceps muscle strength and endurance (proper dd test p=0.016; left dd test p= 0.015 and 30cst p=0.003). changes in quadriceps muscle strength in the right and left dd test between groups showed significant results between the pre-test and post-test between groups (p=0.044 and p=0.039). the delta effect size values of right and left quadriceps muscle strength are 0.626 and 0.612. changes in quadriceps muscle endurance at 30cst between groups showed significant results in the pre-test and post-test between groups (p=0.017). the 30cst delta effect size value is 1.653. adding multicomponent vivifrail© training for four weeks in elderly people with frailty syndrome can increase quadricep muscle strength, measured by the digital dynamometer test, and quadricep muscle endurance, measured by 30cst.
