Opinion paper: Exercise for healthy aging.

The physical demands of daily life in developed countries have decreased remarkably during the last two centuries. General leisure time has increased and the age at retirement has decreased. General health has improved and life expectancy has increased. Most people can expect to live 20-30 years after retirement. By 2050, one in four people in Europe and North America will be aged 65 or over. Furthermore, women live longer than men. Generally, the physical demands on older women will be low. Thus, their physical fitness will decline, which in turn will affect a variety of organ systems and functions, and so impact on mental health, quality of life and independent living. This opinion paper explores exercise strategies for healthy ageing.
