This is a surprising result which appears to contradict the data gathered in similar studies initially. Recently, other studies showed that runners within an ultra marathon experienced elevated DNA damage during the race. This was true of marathon runners soon after the race also. However, these studies didn’t consider competitions which required a period of physical exertion lasting longer than 8 hours, nor was data collected over such an prolonged timeframe as in Prof. Wagner’s project. In total, the Austrian research team took blood samples from the triathletes at five different period points – 2 days prior to the race, then 20 moments and 1, 5 and 19 days after the competition.We then used logistic regression to look for the probability of a maintained practical status versus death or functional decline 12 months after the start of dialysis. As a complementary approach, we used a random-effects model to spell it out the change in functional position from 12 months before to 12 months following the initiation of dialysis. Our base model fit different slopes before and after the initiation of dialysis, allowed a sharp change following the initiation of dialysis shortly, and altered for age group at the initiation of dialysis, sex, and competition. From this base model, the estimate for the initiation-of-dialysis variable indicated the magnitude of transformation in functional status associated with the begin of dialysis.
