Abstract
Background and Aim: During the plateau stage of resistance training, in order to cross this stage, it is necessary to manipulate training variables and apply advanced training techniques. Therefore, the purpose of this study was to investigate the acute effects of sarcoplasmic stimulation and traditional resistance training on muscle thickness, plasma volume, and testosterone to cortisol ratio in bodybuilders during a plateau period. Materials and Methods: A crossover design was conducted with 10 bodybuilding athletes (26.71±4.1 years, 3.5±1.6 years of training experience) participating in two traditional and sarcoplasmic stimulation protocols over an interval of seven days. During the traditional protocol, eight sets were performed at an intensity of 70-80% of one repetition maximum until failure. As the same, for the sarcoplasmic stimulation protocol, six reduction sets were performed (three sets of 70-80%, three sets with a 20% load reduction and one set of isometrics until failure). Buresh formula was used to measure acute muscle thickness of the biceps muscle, Castille’s equation was used to measure changes in plasma volume, and blood samples were taken to determine testosterone and cortisol levels. The difference between the pre-test and post-test values of each variable was determined and the changes were analyzed using the paired t-test at the significance level of p<0.05. Results: The results of the present research showed that the resistance training system with sarcoplasmic stimulation showed significant increase on the acute thickness of the biceps muscle compared to traditional resistance training (p=0.03). However, no significant difference was observed between the two protocols (p<0.05) based on the hormonal response of testosterone and cortisol and changes in plasma volume. Conclusion: In trained individuals, the use of the sarcoplasmic stimulation system appears to be an effective method for passing the plateau stage, despite the lower training volume, it involves more metabolic stress and acute swelling than traditional training.
