Design: A transcultural adaptation and descriptive cross-sectional study. Settings: Jarama motorcycling circuit (Madrid, Spain). Participants: The participants were riders recorded across in a final motorcycling race. Interventions: The study design is based in two tools, the adapted Motorcyclist Questionnaire (MQ-21) with 21 items and Borg CR10 Scale® was used to determine discomfort level during motorcycling performance. The translation procedure, reliability, and reproducibility were performed. Results: All items showed an almost perfect intraclass correlation coefficient (ICC) (ICC = 0.909–1.00), except for item 9 (ICC = 0.881). Almost perfect internal consistency was shown for the total score (Cronbach α = 0.899). No systematic differences existed among test and retest in all items (p > 0.05) according to Bland–Altman plots. Respondents experienced slight discomfort on their body parts during the test-retest 1 h riding process. Foot discomfort was scored as 1.20, being the eighth of the 12 studied body parts. Conclusions: Internal consistency and test-retest reliability of the MQ-21 questionnaire were excellent and this questionnaire may be recommended to be used in motorcycling sports and clinical settings to evaluate the discomfort.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/journal articlehttps://doi.org/10.3390/ijerph17072233https://www.mdpi.com/1660-4601/17/7/2233open accessFoot diseasesreproducibility of resultssportsvalidation studies as topicPodología
