RESUMO

This work was made up of two steps. The objectives of the STEP 1 were to propose and apply a protocol of assessment of the isocinetic muscular strength of shoulder on sedentary ones, male teenagers (n=50). The STEP 2 was to compare the attendance of isocinetic muscular strength between sedentary teenagers (n=20), swimmers (n=10) and volleyball players (n=10). The STEP 1 was made up of four tests: TEST 1: Reliability Test (n=10); TEST 2: The influence of dominancy test between dominant (DOM) and nondominant (NDOM) shoulder (n=10); TEST 3: The order influence test between right and left shoulders (n=10); and TEST 4: Comparison test between the velocities (n=20). In the STEP 2 the proposed and checked protocol in the STEP 1 was applied. For the isocinetic assessment one used the position of 90° frontal plan abduction, for external (ER) and internal (IR) rotation movements, within three velocities in concentric contraction of 120°/s, 240°/s, and 60°/s, and an eccentric velocity of 30°/s. The parameters gotten through this protocol were: peak torque (PT) in (N.m) and PT in relation to the corporal mass, bilateral deficits, ER/IR relation, correlation to the height, span, corporal mass, slim mass, and for swimmers was also correlated to the best time in crawl style. The results of STEP 1 show that the proposed protocol introduces reliability, once there is no significant difference upon beginning an assessment on the DOM or NDOM shoulder, however one needs to consider and keep which shoulder the assessment was begun. The assessed velocities showed distinct PT. In the beginning, in concentric contraction within intermediary velocity of 120°/s, a fast 240°/s, followed by a slow 60°/s, and finally the eccentric slow 30°/s. in the STEP 2, considering N.m/Kg-1, for the group NDOM IR, the swimmers are in relation to the sedentary ones 31% stronger (p<0,05) and, in relation to the volleyball players, the swimmers are 32% stronger (p<0,05). These results denote that the strength features of the ER and IR of shoulder may be acquired according to the specificity of the sport modality. The results show that the proposed protocol introduces reliability since there are no significant differences upon beginning an assessment on the DOM or NDOM shoulder, however we have to consider which shoulder the assessment began and keep the protocol so; the velocities studied characterized themselves significant differences (p<0,05). The protocol has applicability on sedentary ones, swimmers and volleyball players, and can be used as a specific assessment method, and becomes a valuable data resource for the attendance of physical efficiency, lesions prevention and procedure
