Sport injuries in international masters rowers: a cross-sectional study.

AIM: To estimate the frequency and localization of acute (traumatic) and chronic (overuse) injuries in a population of masters rowers with respect to their age subgroups and assess the association between injury occurrence and different training modalities, rowing experience, previous competition level, and current rowing practice.

METHODS: A cross-sectional study was conducted among 743 masters rowers who participated in the 34th International Federation of Rowing Associations (Fédération Internationale des Sociétés d'Aviron, FISA) World Rowing Masters Regatta held in Zagreb, September 2-9, 2007. A rowing-specific questionnaire was used, followed by an interview about the injuries sustained during the 12-month period before the competition.

RESULTS: The mean injury rate per year was 0.48 injuries/masters rower (2.25 injuries/1000 training sessions/rower). The majority of injuries were chronic injuries (the ratio of acute to chronic injuries was 1:1.7), and did not lead to the loss of training/competition time. Of all acute injuries, 49.6% were acquired during rowing-specific training, 43.7% during cross-training, and 6.7% in the gym. The most commonly affected region was the low back (32.6%), followed by the knee (14.2%), shoulder/upper arm, and elbow (10.6% each).

CONCLUSION: International masters rowers sustained predominantly chronic injuries of low severity, and the most commonly injured region was the low back. The mean injury rate per rower per year was lower than the rates previously reported for juniors and seniors.
