Brief 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).

Detailed Description:
A crossover randomized controlled trial. The participation in the study requires only 2 assistances to the data takings that will be developed in the training laboratory of the Faculty of Sciences of Physical Activity and Sport of the European University. 40 amateur cyclists will be randomly assigned to carry out each (2) conditions of intervention: a road bike time trial (CA) and a mountain bike time trial (MT) separated by 7 days washout. \*Randomization marks the order in which participants are subjected to an intervention condition or other.
These sessions will begin with an initial assessment, which will be carried out: an anthropometric assessment (height and weight), followed to an evaluation of the tensiomyographic variable maximal radial displacement (Dm) over the thigh muscles: vastus medialis (VM), rectus femoris (RF), vastus lateralis (VL), biceps femoris (BF), and erector spinae (EE) at the lumbar level, before and after an acute effort (\> 3 hours) in CA and MT bicycle. Respect to pain assessment, it will be measured the intensity pain perception on the lumbar region (LBPP) by using a 0 to 10 numeric pain-rating scale; the pressure pain threshold (PPT) with a manual mechanical algometer; and the functional disability caused by LBP through the Roland-Morris Questionnaire (RMQ).
