Associação entre tipos de pisada e lesões nos praticantes de corrida de rua

Abstract

The street race originated in England in the seventeenth century and is currently one of the most practiced forms in the world. Proof of this is the number of racing events in the United States: more than 17 000 road races, 316 marathons and 930 annual half-marathon. In the search for a healthier lifestyle, many people choose to race as exercise modality, considering a physical activity of low cost, easy implementation and showcasing various cardiovascular and metabolic benefits. On the other hand, the constant practice of the race are causing increasing reports of musculoskeletal injuries among practitioners. Therefore, the objective of the research was to identify the most common injuries in the street racers and verify if there is a relationship between the lesions and the types of trampled. A questionnaire was applied to identify the athlete's profile and the existence of injury. The type of trampled used during the race (support rearfoot, midfoot or forefoot) was quantified using 2D kinematics data observed in the sagittal plane. The 69 subjects volunteers who participated were the age group of 34 years (± 5.5 years). Thirty-six subjects (52.2%) reported having suffered some kind of injury or due to race pain, the knee was the region with the highest frequency of injury or pain (52.8%) and kinematic analysis revealed that 86.9 % of the subjects perform the race with a bruised hindfoot. A binary logistic regression analysis was applied and no correlation was found between the dependent variable (injury) and the covariates age, hours of training per week, kilometers performed in the training sessions per week and type of trampled. Other research should be conducted in order to explain and prevent the appearance of lesions in the knee region in runners.
