Exercise and ageing well - what does physical activity do to our body as we get older?
We spoke to Professors Stephen Harridge and Norman Lazarus about a study that looks to gain greater understanding of the effects of exercise on ageing.
Professor Harridge, who is leading the study, talks about the four different groups of people they are comparing, and how they believe that 'healthspan', or good quality of life, in later years is linked to physical activity.
Professor Norman Lazarus is a co-investigator as well as a participant in the study. At 87 years old, he falls into the master cyclist category. He explains why he took up exercise and the benefits it has provided him throughout his life.
