Prevalence of Acute Injuries in Amateur and Elite Mountain Bikers

Completed

• Conditions: Acute Injury in Mountain Biking

• Registration Number: NCT03690219
• Lead Sponsor: University of Applied Sciences and Arts of Southern Switzerland

Brief Summary

The investigators intented to assess the prevalence of acute injuries in amateur and elite mountain bikers.

Detailed Description

In order to assess the prevalence of acute injuries in amateur and elite mountain bikers a questionnaire was created in accordance to existing literature. The questionnaire was translated in several languages by bilingual people familiar with mountain biking. The questionnaire focussed on demographic data, training volume, number of races per year, number of injuries since practising mountain biking, wearing of protective gear items and accident mechanism. The survey was conducted during the Swiss Epic Mountain Bike Event in 2017. All riders were asked to voluntarily participate in the survey.

Primary Outcome Measures

Name	Time	Method
Prevalence of Injuries in Amateur and Elite Mountain Bikers	At study enrollment, based on participants' self-reported history of mountain bike injuries	In a retrospective questionnaire participants were asked about the "Number of injuries obtained during mountain biking".

Secondary Outcome Measures

Name	Time	Method
Training and Racing Volume	At study enrollment, based on participants' retrospective self-report of the number of races per year and estimated training hours per week	In a retrospective questionnaire the participants were asked "How many races per year" they ride and whats their "Estimated training hours per week in regard to the season".; The number of races per year was multiplied by the factor 4 to transform the number of races into training hours. Then, both values were added to get the training volume per year.
Years Practising Mountain Biking	At study enrollment, based on participants' self-reported history of mountain bike participation	In a retrospective questionnaire participants were asked "Since how many years do you participate in mountain biking?".
Amount of Protective Gear Items	At study enrollment, based on participants' retrospective self-report of protective gear use	In a retrospective questionnaire participants were asked to tick the protective gear (helment, gloves, eveywear, upper armour, lower armout, other) they are using for mountain biking.
Injury Rate Per 1000hrs Exposure Time	At study enrollment, based on participants' self-reported history of mountain bike participation	The injury rate per 1000 hours exposure time was calculated as follows: the hours of exposure time per year were multiplied by the number of years practicing mountain biking to get the total hours at risk. Then, the total amount of injuries ever was divided by the total hours at risk, multiplied by 1000 hours to get the injury rate per 1000 hours of exposure time.
