Abstract

Context

In women, age and the menopausal transition contribute to an increase of body fat and a reduction of lean body mass associated with functional decline, affecting independent living.

Background

Sarcopenia and adiposity in the elderly has been associated with increased mortality and functional decline affecting independent living.

Purpose

This study was conducted to determine the effect of a multipurpose exercise program on the body composition and functional ability of elderly women living in a community.

Design

An 18-month single-blinded RCT comparing participants in an exercise program with an active control group was conducted from May 2005 through December 2007. Analyses were conducted from January 2008 to July 2008.

Setting/participants

Two hundred forty-six women (aged 69.1±4.0 years) living independently in the area of Erlangen–Nürnberg (Germany) participated in the study.

Intervention

Subjects (n=123) performed a multipurpose exercise program with special emphasis on exercise intensity but with low-level requirements for training facilities and materials. The 123 women in the control group focused primarily on well-being.

Main outcome measures

Body composition was assessed by dual-energy x-ray absorptiometry. Further, strength was evaluated using isometric techniques for the back and legs. Aerobic fitness was determined from a progressive-intensity treadmill test.

Results

After 18 months, significant effects in favor of the exercise program for body composition were increases in appendicular skeletal muscle mass and lean body mass along with reductions in abdominal fat and total body fat. Significant performance effects also favored the exercise program and included enhanced isometric maximum trunk-extensor and leg press strength, leg press power, timed up-and-go test, and aerobic fitness.

Conclusions

A high-intensity multipurpose exercise program produced significant improvements in body composition and functional ability in a cohort of elderly women living in a community.
