Aim To measure the effectiveness of a 12-week exercise intervention in reducing the health risks associated with physical decline in people aged 60 and older.

Method An intervention group took part in a 12-week exercise programme. The intervention and comparison groups undertook the Senior Fitness Test at baseline, 12 weeks, six months and 12 months. Focus groups were conducted with the intervention and comparison groups at 12 weeks, then again with the intervention group after 12 months.

Results Fitness increased significantly (P>0.001) after 12 weeks of exercise in the intervention group. Results demonstrated significant difference between intervention and comparison groups’ fitness at six months (P>0.01) and 12 months (P>0.001) respectively. Focus groups supported the results, suggesting exercise increased independence and quality of life.

Conclusion Nurses can promote exercise in patients to reduce social isolation, increase independence and improve quality of life. The findings from this study may be useful during the development of community services for older adults.
