The risk of sports activities--the injuries of the Achilles tendon in sportsmen.

The aim of this study was to determine whether professional sports activities and intensive training practice affect pathological changes of the Achilles tendon. We also aimed to investigate whether these injuries primarily occur earlier or later in life. This was a cross sectional study of 214 athletes and non-athletes between the ages of 17-66. Participants were divided into four groups: 63 active young athletes, 64 young persons not involved in sports, 6 elderly athletes and 58 elderly people who did not participate in intensive athletic activities during their lifetimes. Ultrasound measurements of the Achilles tendon were performed on all participants. All participants also completed a self-administered survey to collect demographic information and data on athletic participation. Data were analyzed using the chi-square test and Fisher's exact test. Overall, those who were active athletes sought medical care more often than those who did not participate regularly in sports. Twenty-seven (33%) of young athletes had some Achilles tendon pathology, compared to 9 (14%) younger non-athletes. A total of 36 (64%) of elderly athletes were diagnosed with Achilles tendon disorders, compared to 15 (26%) of elderly people who were not active in sports. Microtears, acute tendonitis and peritendonitis were associated with younger age. By contrast, calcifications, scar tissue, and partial or complete rupture were only seen in the elderly
