Introdução: A diminuição da capacidade de exercer esforços por parte dos músculos rotadores pode criar uma variedade de problemas. O conhecimento preciso do nível de força muscular de um indivíduo é importante, tanto para a avaliação da capacidade funcional ocupacional, como para uma apropriada prescrição de exercícios atléticos e de reabilitação. Percebe-se escassez de informação sobre as articulações do ombro, bem como os fatores envolvidos na força muscular dessa região. O objetivo deste estudo foi comparar a força gerada pelos músculos do manguito rotador entre o membro superior direito e o membro superior esquerdo em indivíduos saudáveis. Métodos: Participaram do estudo 22 sujeitos do sexo masculino, com idade de 18 e 19 anos, militares, saudáveis e sem história clínica de patologia ortopédica ou qualquer tipo de lesão no sistema musculoesquelético. Foram aplicados dois testes de força: Rotação Interna e Rotação Externa. Resultado : A força média de rotação interna no membro superior direito (MSD) foi maior que a força média de rotação interna no membro superior esquerdo (MSE) (p=0,723) e a força de rotação externa no MSD foi menor que a força média de rotação externa no MSE (p=0,788). Não houve diferença estatística na comparação dos valores de força de todos os testes de força isométrica. Conclusão: Para amostra estudada e metodologia utilizada na avaliação da força muscular, não houve diferença estatística na comparação da força gerada pelos músculos do manguito rotador do membro superior direito e do membro superior esquerdo.Rotator Cuff Muscle Strength in Healthy Individuals Introduction: Decreased ability to exert efforts by the rotator muscles can create a variety of problems. The precise knowledge of the level of muscular strength of an individual is important for both the functional capacity evaluation for occupational as an appropriate exercise prescription and rehabilitation of athletic. It is perceived scarcity of information on the shoulder joints as well as factors involved in muscle strength in this region. Objective: Develop a device for measuring the strength generated by the muscles of the upper limbs and the verification of efficiency and adaptability of this device through a comparative study of muscle strength in healthy subjects. Methods: The study included 22 male subjects, aged 18 and 19 years, military personnel, body mass between 57.7 and 93 kg (71.8 ± 9.45 kg) and height between 1.67 and 1.90 m (1.75 ± 0.06 m), healthy and without a history of orthopaedic disease or any kind of damage to the musculoskeletal system. Three strength tests were applied: Internal Rotation and External Rotation. For each type of effort three maximum voluntary contractions were required for 10 seconds, with an interval of 30 seconds between each contraction.  Results: Internal rotation in the right upper limb (RUL) was higher than the average strength of internal rotation in the left upper limb (LUL) (p = 0, 723) and the external rotation strength in RUL was lower than the average strength of external rotation in the LUL (p=0,788).  No statistical difference in comparing the strength values of all isometric strength tests. Conclusion: For sample and methodology used to assess muscle strength, there was no statistical difference in comparing the force generated by the muscles of the rotator cuff of the right and left upper limb.

Adrenergic Effects

The effect of beta-adrenergic agonists on splanchnic intravascular volume (SIV), measured with radionuclide imaging, and the subsequent influence of such volume changes on cardiac output (CO) were examined in 40 anesthetized dogs. Isoproterenol (6 micrograms/min) caused a decrease in total SIV of 12 +/- 1% (P less than 0.001). The decrease was due entirely to a decrease in splenic volume of 24 +/- 3% (P less than 0.001), since volume increased in the remainder of the splanchnic vasculature [hepatic and mesenteric volume increased 12 +/- 2% (P less than 0.001) and 11 +/- 3% (P less than 0.02), respectively]. CO increased from 1,724 +/- 187 to 3,138 +/- 321 ml/min (P less than 0.001); after subsequent splenectomy, isoproterenol caused a similar increment. Isoproterenol-associated SIV changes were not altered by carotid denervation and vagotomy or by beta 1-adrenergic inhibition with metoprolol but were abolished by nonselective beta-adrenergic inhibition with propranolol. With a larger dose of metoprolol and smaller dose of isoproterenol to minimize beta 1-adrenergic effects, the isoproterenol-associated CO increment was attenuated (P less than 0.01) by splenectomy. With the beta 2-agonist terbutaline (41 micrograms/min) after metoprolol, total SIV decreased 15 +/- 4% (P less than 0.001). After subsequent alpha-adrenergic inhibition with phenoxybenzamine, terbutaline caused no change in SIV and an attenuated (P less than 0.05) increase in CO. Thus beta-adrenergic agonist administration causes a decrease in total SIV due entirely to a decrease in splenic volume. The SIV decrement is dependent on beta 2- and alpha-adrenoceptor stimulation and appears to enhance CO only if beta 1-adrenergic effects are minimized.
