WASHINGTON: Playing outdoor games regularly reduces the risk of developing blood clots by 39 per cent in women and 22 per cent in men, according to a study published in Journal of Thrombosis and Haemostasis.
Researchers from Leiden University Medical Center in the Netherlands evaluated 7,860 people in the 18 to 70 years age group. They compared patients who had suffered their first blood clot in a leg vein or lung artery with control subjects who had never experienced blood clots.
Thirty-one per cent of the patients and 40 per cent of the control subjects participated in sports on a regular basis.
The study revealed that participating in sports at least once per week, regardless of the type of sport or its intensity, reduced the risk of developing a blood clot in a lung artery by 46 per cent and in a leg vein by 24 per cent.
The results were applicable to both men and women.
In fact, the study’s co-author F.R. Rosendaal said: â€œWomen were shown to be even more likely to reap the benefits of regular sporting activities than men. When we excluded women who were pregnant or receiving oral contraceptive or hormone replacement therapy â€“ all possible causes of blood clots â€“ the risk for women was reduced by 55 per cent.â€
Although strenuous activity is known to increase the risk of blood clot development in old age, the net effect of participation in sports by old people may be positive.
The study also revealed that people who did not participate in sports were more than four-times as likely to develop a blood clot if they were obese than their lean counterparts.
â€œWhen we looked at the results, we found that, overall, the mere fact that people took part in a sporting activity at least once a week was enough to lower their risk of blood clots,â€ say the authors.
