摘要：AbstractThis research started from the necessity of instituting a physical therapy intervention program that would ensure the continuity of technical instruction in parallel with a correct and complete rehabilitation of the injured functions. The physical therapy intervention consisted in setting the short term objectives of physical therapy: reducing physical effort, diminishing the pain and the inflammatory process, increasing the range of motions in flexing the calf on the thigh (first without loading, then with loading the limb), strengthening the calf and thigh muscles (agonist and antagonist muscles), and rebuilding and increasing the antero-posterior stability of the knee, this last objective being the central element of the physical therapy intervention for consolidating the results obtained and preventing future injuries. From a technical standpoint, linked imitative performances were used (in-run – take-off – flight – landing positions), both from a fixed and from a moving position – on a wheel cart and on skis, then the training continued on a jumping hill, where there was an optimal ratio between the in-run speed, the length of the jump, and the landing surface. The results obtained at the Liberec Junior World Championship in January 2013 (19thposition), the best Romanian result, confirms the success of this program.
