Objective: To describe the incidence, severity, type, and anatomical distribution of injuries in a Spanish field hockey club during three consecutive seasons (2002-2003, 2003-2004 and 2004-2005). Material and methods: We retrospectively compiled all the injuries occurring in the male and female teams of the honor division, with 18 players each. We added the total time (hours) of practice sessions and matches to quantify the hours of exposure and calculated the injury incidence rate through the following formula: (number of injuries/exposure hours) * 1,000 hours. Results: The severity of injuries was defined by the time during which the hockey player could not play (minor: < 7 days, moderate: 8-28 days and severe: > 28 days). Women had a slightly higher injury incidence rate than men (27.70/1,000 hours vs. 27.64/1,000 hours). The Injury incidence rate during matches was higher than that during practice sessions in both sexes (38.37/1,000 hours vs. 24.32/1,000 hours in men and 30.74/1,000 hours vs. 27.70/1,000 hours in women). Most of the injuries affected the lower limbs (64.6%), the trunk (25.6%), the upper limbs (8.89%), and the head (0.84%). The most commonly affected anatomical area was the thigh (23.9%), followed by the leg (11.53%) and the ankle (10.27%). The injury with the highest incidence was delayed onset muscular soreness (DOMS) (15.45/1,000 hours), followed by overuse syndrome (3.84/1,000 hours) and muscle strain (3.24/1,000 hours). Most of the injuries were minor (90%), showing a high incidence between March and May and during the months of October and November.
