摘要：Brown A, Vianna J, Dias I, Miranda H, Rodrigues Neto G, Novaes J. Acute Joint Range Effects of Exercises at Different Strength Intensities on Unstable and Stable Platforms. JEPonline 2014;17(6): 74-80. The purpose of the study was to compare the joint range effects of bench press (BP) exercises at different strength intensities when using an unstable platform (UP) and a stable platform (SP). Twenty-six men performed BP tests at 60% and 80% of 1RM using an UP and a SP. Joint amplitude was significantly higher at 80% of 1RM than at 60% of 1RM on both platforms when measuring flexion (P<0.001) and abduction (P=0.001). Abduction (P=0.03) and adduction (P=0.005) were significantly higher after exercises performed on an UP than on a SP. The comparison of the pre-test and the post-test results showed that flexion, abduction, and horizontal adduction were significantly higher at 80% of 1RM when using an UP. Thus, the findings indicate that performing the BP exercise at high intensity using an UP can improve the range of movement in trained men.
