BackgroundDuring the recent years, an increase in the number of people practicing recreational mountain biking has been observed. The high-risk sport can cause severe injuries. The most severe injuries involve paralysis and head traumas. These injuries occur to recreational bikers as well as professionals. The purpose of this study is to describe the development in severe injuries and the effort of increasing the safety of mountain biking for recreational bikers.MethodRegister-based study with the population of residents in the municipality of Odense who were injured in a mountain bike incident between 2005 and 2021. Data was obtained from the register of the emergency department, where all contacts are registered. The incidence risk for men and women has been calculated, as well as the distribution between age groups and the mechanism of the fall.ResultsA total of 303 severe injuries during the study period illustrates an increase in both the number of injuries and the number of severe injuries. Most of the injuries occur among men aged 40-49. The proportion of severe injuries rises to around 40 % after 2015. The incidence risk was 59 per 10.000 (95 % CI: 53-66) in total, for men 68 per 10.000 (95 % CI: 61-77), and for women 22,6 per 10.000 (95 % CI: 16-31,5).ConclusionThere has been an increase in the number of severe injuries, non-severe injuries, and the proportion of MTB injuries from 2005 to 2020. After 2020, there is a decrease in the number of severe injuries.Copyright © 2024 The Author(s). Published by Elsevier Ltd.. All rights reserved.
