先前的研究表明,在气候温暖时参加过于剧烈的活动,如军事训练,会损害人的肾脏。但人们对马拉松所造成的影响则知之甚少。
A team of researchers led by Professor Chirag Parikh, of Yale University in the US, studied a small group of participants in the 2015 Hartford Marathon.
由美国耶鲁大学教授齐拉格•帕里克领导的研究小组对2015年哈特福德马拉松赛部分参赛者进行了测试。
They collected blood and urine samples before and after the event. They analysed a variety of markers of kidney injury, including serum creatinine levels, kidney cells on microscopy, and proteins in urine.
在比赛前后,他们分别收集了受试者的血样和尿样。他们检测了各种肾脏损伤标志物,包括血清肌酐水平,显微镜下的肾细胞和尿液中的蛋白质。
The researchers found that 82 percent of the runners that were studied showed Stage 1 Acute Kidney Injury (AKI) soon after the race. AKI is a condition in which the kidneys fail to filter waste from the blood.
研究人员发现,82%的受试者在比赛结束后不久就显示出了第一阶段急性肾损伤 Prof Parikh said: "The kidney responds to the physical stress of marathon running as if it's injured, in a way that's similar to what happens in hospitalised patients when the kidney is affected by medical and surgical complications."
