Modelo para ajustes dos componentes da bicicleta de ciclismo indoor

Abstract

Cycling is among the sporting activities with the largest number of practitioners in t he world, with substantial increase in the last decade, indoor cycling. It also came to have a popularity that has been reinforced by studies that report benefits of aerobic exercise, safety, comfort and the restricted environment of gyms. Due to inadequate ergonomic use, cyclists are often hampered by repetitive strain injuries, leading to decreased frequency of bicycle use. A problem also found in indoor cycling, which in addition to addressing topics such as level of training and physical assessment as preventive forms of injury, addressed as a primary requirement, optimal regulation of the components of stationary cycling indoor cycling. Therefore, it is extremely important to develop a science-based method such as ergonomics and biomechanics of cycling, based on established angles to properly position the cyclist on the bicycle. Thus, the objective of this study was to elaborate a theoretical model for the accomplishment of adjustments of the components of the stationary bicycle of indoor cycling, with the purpose of reducing the incidence of injuries or pain in the joints of spinning practitioners. The research had two stages, the first being descriptive and the second exploratory. In the first stage, a literature review was carried out to understand the current trends regarding adjustments of bicycle components and injuries in the practice of cycling, with a search in the main health databases being carried out first, to elaborate a theoric model. In the second stage, the research proceeded based on the researched literature, to elaborate a model of adjustments of the components of the indoor cycling bicycle and then apply in a case study, in which there was an intervention in the adjustments of the components of the indoor cycling bicycle. The research was elaborated in the city of Campina Grande - PB, being the second stage realized in Fit Club academy. The second stage was composed of 1 participant, with the inclusion criteria being that the cyclist practiced spinning classes regularly, was male, adult, had no history of injuries and also did not present degenerative articular diseases, unless it was related to the practice of cycling. The participant also had to be willing to answer the questionnaire that was applied about musculoskeletal symptoms in the practice of indoor cycling and sign the Term of Free and Informed Consent. To evaluate the time of practice of indoor cycling, weekly frequency and musculoskeletal symptoms related to cycling, a questionnaire was elaborated based on the validated Nordic Questionnaire of Musculoskeletal Symptoms. With this, it is expected that with this basic research, to enable a model that helps to reduce the incidence of injuries and pain associated with improper positioning on the indoor cycling bicycle.
