Muscle mass, strength, power and physical performance and their association with quality of life in older adults, the Study of Muscle, Mobility and Aging (SOMMA).

ABSTRACT:

Background

Sarcopenia negatively impacts quality of life. It is unclear whether different measures of muscle size, strength, physical performance, and fitness have similar associations with quality of life.

Objective

To describe associations of sarcopenia metrics with quality of life outcomes.

Participants

Community-dwelling adults aged 70+ years participating in the SOMMA (Study of Muscle, Mobility and Aging) study.

Design and settings

Two academic medical centers.

Measurements

Measures included muscle size (MRI- muscle volume. D₃Cr muscle mass); strength and power (grip strength, leg extension power and strength); walking and physical performance (4m and 400m walk, SPPB (Short Physical Performance Battery), stair climb, chair stand); fitness
