Introduction: Strength training is a popular and effective modality for improving muscle function, functional performance and health parameters in a wide range of healthy and clinical populations. This type of training is recommended as an interventionist strategy for the general population. Among the modalities present in strength training, Paralympic Powerlifting (PP) is observed as a sport that focuses on the development of maximum strength in the bench press exercise. Objectives: to evaluate the effects of different traditional (TT) and eccentric (ET) training methods on maximal isometric strength (MIF), time to maximal isometric strength (Time), muscle electrical activity (AEM), skin temperature (Tsk) in PP. Methods: The sample consisted of 12 male subjects, classified in the top ten of their categories, (30.25 ± 8.13 years; 72.36 ± 18.47 kg). The study was carried out over a period of three weeks. Data were collected before, after (immediately), 24h and 48h after the procedure. Results: In the sternal chest, there was a difference in the ET in the moments before and 24h and before and 48h. In the pectoral clavicular, there was a difference in the ET in the moments before and 24h and before and 48h. There was also a difference in the 24h time between the training methods. In the deltoid, there was a difference in the ET in the moments before and 24h. There was also a difference in the 24h time between the methods. In the triceps, there was a difference in the ET in the moments before and after and before and 48h. There was also a difference in the 24h time between the methods. There was no difference in sEMG in the different muscles in relation to the training methods. In the FIM, there was a difference in the TT in the moments before and after, after and 48h and 24h and 48h. In the ET there was a difference in the moments before and after and after and 48h. There were also differences at the 48 h time between the training methods. In Time, there was no difference between the methods. Conclusion From the results found by our study, we observed that TE promoted increases in Tsk recorded up to 48 after the training session, indicating greater muscle fatigue. However, the same did not happen with the TT. It was possible to notice even greater production of FIM, indicating that the athletes continued to have muscle fatigue even after performing the ET method.
