[Autom. eng. transl.] Flexibility, understood as the joint response to movement, is an important component, often overlooked, of physical fitness. Often the problems affecting the lumbar area are due to the incorrect alignment of the vertebrae of the spine and the pelvic fascia. The capacity for joint mobility and that of muscular elasticity are strictly interdependent but disjointed capacities, in that joint mobility or flexibility is defined as the ability of our joints to allow us the smooth execution of movements at their maximum amplitude, while elasticity muscular is the ability of the skeletal muscle to allow itself to be stretched and to recover its physiological length without suffering trauma. Their mutual dependence is obvious because the mobility depends on the anatomical-structural characteristics of the joints but also on the capacity of the antagonist muscles that affect their movements to lengthen easily. The joint mobility and the flexibility of each of us varies according to the following factors: individual congenital factors linked to the elastic-structural characteristics of the joint capsules, ligaments and muscles; factors related to development, age and sex (in the child the laxity and softness of the ligaments and joint capsules is greater than in the adult and the female, compared to the male, shows a greater mobility); factors dependent on the habitual use of the joints that can undergo a process of increase or decrease of mobility following the presence or not of functional stresses generated by the amplitude of the segmentary movements that are of interest to it. The elderly subject is led, due to culture and wrong habits, to move less and less with reduced joint movements, progressively losing amplitude in joint excursions. The role of the joints of our body is twofold: to allow the movement of the bony heads and at the same time guarantee the stability of the bone structure in the various postures in opposition to the force of gravity. For this reason it becomes important to clarify that joint mobility must be improved only when it is necessary for maintaining the physiological mobility that allows man to move.
