Summary
Introduction: Cycling represents a very important level of practice, being among the most practiced sports in Spain. As in any other sport discipline, its practice is associated with the appearance of overloads and sports injuries. Specifically, the 2 most affected areas are the lumbar and knee areas, with an annual prevalence of 58% and 36%, respectively. There is no clear hypothesis to explain the low back pain associated with the practice of cycling, but several authors agree that it may be due to holding an inverted posture of the rachis and the characteristics associated with this sport: long duration, static posture, high intensities, vibrations generated by the terrain, and so forth. The project proposes to analyze the acute effect of a long-lasting bicycle trip (3 hours) on the muscles involved in low back and knee pain, see, lumbar paravertebral, quadriceps and hamstrings, by means of tensiomyography (TMG).
Objectives: the main objective of this study is to evaluate the behavior of the mechanical characteristics of the lower back and thigh muscles, by means of tensiomyography, in amateur cyclists after an acute effort on road and mountain bikes, and to study their possible relationship with low back pain (LBP).
