The Claim
In community-dwelling older women aged 65 and above without sarcopenia, higher skeletal muscle mass index is significantly associated with better instrumental activities of daily living and social role function, as measured by the Tokyo Metropolitan Institute of Gerontology Index of Competence, after adjustment for age, fat mass, and handgrip strength.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Older women aged 65 and above with more skeletal muscle mass tend to perform better in daily tasks such as managing finances, shopping, and social activities, even when accounting for their age, body fat, and hand strength.
See the scientific wording
In community-dwelling older women aged 65 and above without sarcopenia, higher skeletal muscle mass index (SMI) is significantly associated with better instrumental activities of daily living (IADL) and social role function, as measured by the Tokyo Metropolitan Institute of Gerontology Index of Competence, even after adjusting for age, fat mass, and handgrip strength, suggesting that muscle mass may play a role in maintaining complex daily activities that require physical engagement.
More muscle tissue provides stronger and more coordinated signals to the brain during movement, allowing older women to perform daily tasks like shopping or managing finances with less effort and better balance, even when their grip strength and body fat are accounted for.
What the research says
1 studyStudy: Skeletal Muscle Mass and Higher-Level Functional Capacity in Female Community-Dwelling Older Adults
In older women who are still healthy and not weak, those with more muscle mass were better at doing everyday tasks like shopping and visiting friends, even when their strength and age were taken into account.
