The Relationship Between Intermuscular Fat and Physical Performance Is Moderated by Muscle Area in Older Adults.

ABSTRACT:

Background

Age-related deposition of fat in skeletal muscle is associated with functional limitations. Skeletal muscle fat may be present in people with preserved muscle mass or accompanied by muscle wasting. However, it is not clear if the association between muscle fat deposition and physical performance is moderated by muscle mass.

Objective

To determine whether the association between midthigh intermuscular fat and physical performance is moderated by muscle area.

Methods

We performed a cross-sectional analysis of the Health, Aging, and, Body Composition (ABC) study data collected in 2002-2003 (n = 1897, women: 52.2%). Midthigh muscle cross-sectional area (by computed tomography) and physical performance measures were compared across quartiles of intermuscular fat
