Abstract

Objective: To determine (1) lean and fat body compartments, reflected by fat-free mass (FFM), appendicular skeletal muscle mass (ASMM), body cell mass (BCM), total body potassium (TBK), fat mass and percentage fat mass, and their differences between age groups in healthy, physically active subjectsfrom 18 to 94 y of age; and (2) if the rate of decrease in any one of the parameters by age might be accelerated compared to others. Methods: A total of 433 healthy ambulatory Caucasians (253 men and 180 women) aged 18-94y were measured by dual-energy X-ray absorptiometry (DXA) andwhole body scintillation counter (TBK counter) using a large sodium iodidecrystal (203 ram diameter). Results: The ASMM change (-16.4 and -12.3% in men and women, respectively)in > 75 y-old compared to 18 to 34-y-old subjects was greater than the FFMchange (-11.8 and -9.7% in men and women, respectively) and this suggests that skeletal muscle mass decrease in older subjects was proportionally greater than non-skeletal muscle mass. BCM (-25.1 and -23.2% in men and women,respectively) and TBK differences were greater than the differences in FFMor ASMM suggesting altered composition of FFM in older subjects. Women hadlower peak FFM, ASMM, BCM and TBK than men. Conclusions: The decline in FFM, ASMM, BCM and TBK is accelerated in men and women after 60 y of age and FFM, ASMM, BCM and TBK are significantly lower than in younger subjects. Fat mass continued to increase until around 75y. Sponsorship: Foundation Nutrition 2000Plus, Geneva, Switzerland.
