Stattin K, et al. - Researchers investigated whether there was an association between physical exercise and the risk of different types of fractures, particularly in highly active individuals. A cohort of 118,204 men and 71,757 women who from 1991 to 2009 took part in Vasaloppet, a long-distance cross-country skiing race in Sweden, and 505,194 nonparticipants frequency-matched on sex, age, and county of residence from the Swedish population was examined. It was observed that high levels of physical exercise were correlated with a slightly higher risk of fractures of any type, including forearm fractures, but a lower risk of hip, proximal humerus, and lower leg fractures.
