Older cyclists have boosted immune systems
A study conducted by the University of Birmingham has found that older cyclists maintain better muscle mass and testosterone levels compared to adults who do not exercise regularly. Regular exercise also benefits the immune system of older people, which scientists found was as effective as that of the younger generations. The study found that regular exercise played a key role in maintaining the Thymus, a key organ which produces T-cells. Normally the Thymus begins to shrink from age 20, but regular exercise has been shown to reduce this effect.
