Fat mass modifies the association of fat-free mass with symptom-limited treadmill duration in the Coronary Artery Risk Development in Young Adults (CARDIA) Study.

ABSTRACT:

Background

The assessment of fat mass and fat-free mass in relation to the symptom-limited maximal exercise duration (Max(dur)) of a treadmill test allows for insight into the association of body composition with treadmill performance potential.

Objective

We investigated the complex associations between fat mass and fat-free mass and Max(dur) in a population setting.

Design

The Max(dur) of a graded exercise treadmill test and body composition by dual-energy X-ray absorptiometry were estimated in 2413 black and white men and women aged 38-50 y from the Coronary Artery Risk Development in Young Adults (CARDIA) cohort.

Results

The mean Max(dur) was ≈7.5 s shorter per kilogram of fat mass in both men and women and independent of fat-free mass, height, race, televis
