During recent years, as many as five Norwegian Olympic medal winners in cross-country skiing have undergone surgery because of low back pain. Based on these high-profile cases it has been speculated that low back injury may represent an occupational hazard for cross-country skiing on the elite level. A new study from the Oslo Sports Trauma Research Center published in the new issue of Spine compares the prevalence of low back pain between endurance sports with different loading characteristics on the spine: Cross-country skiing, rowing, and orienteering. The results show that symptoms were somewhat more common in skiing and rowing, and that they were related to training load and technique.
