Is aerobic exercise the key to successful aging Some researchers have speculated that the most pervasive anti-ageing effects of exercise may occur at the tips of our chromosomes
Aerobic activities like jogging and interval training can make our cells biologically younger, according to a noteworthy new experiment. Weight training may not have the same effect, the study found, raising interesting questions about how various types of exercise affect us at a microscopic level and whether the differences should perhaps influence how we choose to move.There is mounting and rousing evidence that being physically active affects how we age, with older people who exercise typically being healthier, more fit, better muscled and less likely to develop a variety of diseases and disabilities than their sedentary peers. But precisely how, at an interior, molecular level, exercise might be keeping us youthful has not been altogether clear. Past studies have shown that exercise alters the workings of many genes, as well as the immune system, muscle-repair mechanisms and many other systems within the body.
