Regular exercise in middle age protects against age-related muscle deterioration

Washington, Dec. 16 : A new study has suggested that regular exercise in middle age is a protective factor against sarcopenia and effective in maintaining muscle strength and physical performance.


Sarcopenia is a disease associated with the ageing process, resulting in loss of skeletal muscle mass and muscle strength and function in the elderly. The multiple adverse health outcomes include physical disability, poor quality of life and premature death.

The cross-sectional study by investigators from Tokyo University assessed the prevalence of sarcopenia and its association with physical performance in 1000 elderly Japanese participants in the Research on Osteoarthritis or Osteoporosis Against Disability (ROAD) Study.

Handgrip strength, gait speed, and skeletal muscle mass were measured and other information collected, including exercise habits in middle age.

The prevalence of sarcopenia was 13.8 percent in men and 12.4 percent in women, and tended to be significantly higher with increasing age in both sexes.

Analysis showed that exercise habit in middle age was associated with low prevalence of sarcopenia in older age and was significantly associated with grip strength, gait speed, and one-leg standing time after adjusting for age, sex and BMI.

The study was presented at the IOF Regionals 4th Asia-Pacific Osteoporosis Meeting, being held in Hong Kong.
