ACUTE EFFECTS OF DIFFERENT STRENGTH INTENSITIES ON UNSTABLE AND STABLE PLATFORMS ON STRENGTH PERFORMANCE AND SUBJECTIVE EFFORT PERCEPTION IN BENCH PRESS EXERCISE
Journal Title: Medicina Sportiva - Year 2014, Vol 18, Issue 4
Abstract
Introduction: The Swiss ball is an unstable platform that is becoming an important tool in the application of strength exercises because of the greater requirements on the neuromotor and neuromuscular systems.Objective: To investigate whether a change in the type of platform in different intensities (60 and 80% 1MR) in bench press exercise can affect the strength performance and the subjective effort perception (SEP) of trained men.Methods: Twenty-six apparently healthy men (23.2 ± 3.7 years, 1.77 ± 0.07 m, 79.6 ± 12.3 kg, 25.4 ± 2.9 kg/m2) performed the test and retest of 1RM of a bench press (BP) on a stable platform (SP). The subjects were randomly divided into four experimental situations, in which all of them performed the BP tests at 60% and 80% of 1RM on the UP and 60% and 80% of 1MR on the SP.Results: The strength performance (the number of repetitions and total volume) of the BP exercise was significantly higher on a SP compared to an UP (P < 0.001) for both intensities. The SEP was significantly higher on the UP compared to the SP (P < 0.001) and at an intensity of 80% of 1RM compared to 60% of 1RM (P < 0.001).Conclusion: Acutely, regardless of the intensity, the BP exercise promotes better strength performance when performed on a SP and provides a greater effort sensation when performed on the UP.
