Studies carried Faculty of Medicine, University of California found that women with too much sitting, and rarely exercise, aging faster. The study was conducted on 1500 middle-aged women, aged between 64 and 95 years. They were required to answer a questionnaire and wearing a tool to measure their daily activity levels. From the research, it was found that they were more sedentary and less exercise, the cells are 8 years older than the age of the original. “Our study proves that cells grow old faster if they rarely exercise. It shows that chronological age does not always correspond to biological age, “said the chairman of Aladdin Shadyab study, reported by WebMD. Nonetheless, Shadyab mention that the research did not find out the causation between aging and lack of exercise.
“But this study shows that exercise is important and should begin at a young age, and done regularly, it becomes part of everyday life until old age,” said Shadyab. Furthermore, Shadyab found that women who sit for more than 10 hours per day, had a protective measure or chromosomal telomere shortening. In fact, the telomeres protects the chromosomes from damage. “Telomeres naturally shorten with age indeed, but lifestyle also it can affect telomere,” said Shadyab, who calls shorter telomeres could increase the risk of heart attack, diabetes, and cancer. “We found that women were more sedentary, had shorter telomere size,” explained Shadyab. But, it does not happen if they exercise at least 30 minutes a day. Shadyab and his colleagues plan further research to further examine the link between exercise and telomere length at the young age of respondents, also in men. The study was published online on January 18 in the American Journal of Epidemiology.
