달리기도 과유불급이라는 말을 일깨우는 연구결과가 나왔다. 뉴욕타임스는 마라톤 풀코스인 42.195km 보다 긴 거리를 달리는 울트라마라톤이 건강을 해친다고 전했다.
스탠포드대학과 캘리포니아대학 연구진들이 울트라마라토너 1200명 조사한 결과 장거리 달리기가 호흡기나 무릎질환을 일으킨다는 점을 밝혔다.
조사자 중 3분의 1 가량이 달리기 후 알러지나 천식을 앓았다. 연구진은 실외에서 장시간 달리면서 먼지, 꽃가루 등에 노출되기 때문이라고 밝혔다. 더불어 오래 달리는 동안 무릎에 무리를 주어 부상 당하는 경우가 많았다.
연구진은 달리기가 고혈압, 심장질환 예방에 탁월하다고 밝히며 하루에 1.6km 이상 달리지 않을 것을 권고했다.

Ultra-marathon runners more prone to breathing problems
A new study on ultra-marathon runners, who compete in events longer than marathons, showed that these runners tend to be older and have different health concerns than other runners, The New York Times reported.
Researchers at Stanford University and the University of California, Davis, recently studied more than 1,200 experienced ultra-marathon runners.
The runners reported a high incidence of breathing problems. Almost a third told researchers that they experienced either allergies or asthma, often after running. The researchers noted since ultra-long-distance runners spend many hours outside, they are more likely to be exposed to pollen.
But the runners also had a low incidence of high blood pressure and irregular heartbeat. The researchers recommended running no more than 1.6 km a day.
