The diseases caused by incorrect saddle height
There are several diseases associated with incorrect saddle height, is too low than too high, let's analyze the main.
Chondropathy femoro patellar: a saddle too low causes excessive knee that could go in against a process inflammatory, in these cases it is wise to position the seat higher than normal, excluding efficiency biomechanics.
Back pain: height of the saddle too high can lead to back pain caused by an abnormal work of the pelvis and back muscles of the back.
Patellar tendinitis: in this case a saddle positioned below can cause inflammation.
Tendonitis leg goose: here is the height of the saddle was too high to give birth any inflammation.
Tendinitis of the lateral collateral ligament: in this case, the inflammation can be generated by a saddle too low
Not directly related, then at the height of the seat there are two other diseases which can otherwise result from a saddle too high neck pain and carpal tunnel inflammation. In both cases a high-riding leads to a wrong positioning in the saddle with an excessive load weight on the wrists and an accentuation of cervical lordosis.
Many argue that the saddle should be placed Mtb lower, with a similar rule, if not equal to that of the method of the equilibrium position. This method can be adapted to less experienced discipline, encouraging and facilitating contact with the ground in the most difficult. Most experts instead should implement the same system of road racer, as the optimal working angle of the leg muscles do not vary depending on the transition road-mtb.
City Bike and children
City Bike should be in the saddle at a height that enables an easy contact with the ground especially if you ride in city centers. Same caveat with children, whether a beginner, so as to give them greater confidence and security. In the future, then, can raise the saddle quietly.
Pedals and shoes
Pedals and shoes, always change the actual height of the saddle whenever you change your shoes or pedals is well then proceed with a new measurement of the real seat (inside the shoe, the surface of the saddle) in order to prevent interference muscle-tendon caused just by a different height of the saddle.
Final comments and personal experiences
The determination of the correct saddle height requires a number of choices are not indifferent, and that may be agreed with the athlete, that unlike many "biomechanical-whole" that one and only consider the ideal location. The determination of the latter can not escape, then, an analysis of pedalling of the athlete, of any musculoskeletal disorders, mainly dependent on the knee, or predisposition to such efforts, the goals that we want to achieve, in addition to the physical qualities the same and its musculature. Changes the height of the saddle should be done gradually and always, always following the athlete and listening to his impressions, particularly concerning any unusual muscle pain or fatigue. Methods Zani-Pruitt-Haushalter are, in no uncertain terms, the best to prevent possible disease in the knee and lead to efficient and profitable ride, are without doubt the best ways that an amateur could take. The latest methods in biomechanics at the knee angle between 130 and 135 degrees are even more effective in terms of biomechanics, but expose the athlete to a number of possible diseases should not be underestimated. In any case, the correct determination of the height of the saddle should be identified with a dynamic analysis of pedalling, the only one able to understand the exact and real working angles of the knee. Experience, then, points out that if one part car-knee angle (131 degrees) improves the roundness of the ride, its speed and efficiency, the other also leads to increased muscle fatigue, which remains the most contracted. Using the method Zani, however, the muscle is stretched more, you oxygenate better, and the long distances seems to suffer less fatigue. Ultimately a more open angle at the knee seems to have benefits in the long distances, at least in some athletes. By contrast a more closed angle seems to have more performance over shorter distances. That is why an optimal position of the saddle, especially for an agonist can not be determined after a few minutes in a biomechanical center, but it needs a long period of study and analysis to determine, based on the characteristics and needs of the athlete, what is the optimal position for the same, that is to be found in the range in the angle formed by the knee between 131 and 155 degrees.
