Cycling Regularly Can Keep You Younger, Study Finds
Researchers at the University of Birmingham and King’s College London in the United Kingdom have found that staying active cycling keeps the body young and healthy
The study recruited 125 amateur cyclists aged 55 to 79, 84 of which were male and 41 were female. The men had to be able to cycle 100 km in under 6.5 hours, while the women had to be able to cycle 60 km in 5.5 hours. Smokers, heavy drinkers and those with high blood pressure or other health conditions were excluded from the study.
The authors then compared the cyclists to people in their same age group who did not exercise regularly, as well as younger adults between ages 20 and 36.
The findings showed that the cyclists preserved muscle mass and strength with age while maintaining stable levels of body fat and cholesterol. In men, testosterone levels remained high. More surprisingly, the anti-ageing effects of cycling appeared to extend to the immune system.
Not only was T-cell activity higher in the active adults than the inactive men and women, but the cyclists were also producing the same level of T-cell activity as young adults in their 20's.
“The immune system declines by about 2-3% a year from our 20s, which is why older people are more susceptible to infections, conditions like rheumatoid arthritis and,
potentially, cancer,” study author and professor Janet Lord.
Prof Norman Lazarus of King’s College London, who took part in and co-authored the research, said: “If exercise was a pill, everyone would be taking it. It has wide-ranging benefits for the body, the mind, for our muscles and our immune system.”
“Being sedentary goes against evolution because humans are designed to be physically active”, said Steve Harridge, co-author and professor of physiology at King’s College London.
“You don’t need to be a competitive athlete to reap the benefits – or be an endurance cyclist – anything which gets you moving and a little bit out of puff will help.”
