Analysis of Post-Exercise Acute Hemodynamic Sustainability in Different Training Methods in Paralympic Powerlifting Athletes

Background: Paralympic powerlifting (PP) is one of the sports modalities that uses strength training with high loads, causing various physiological responses resulting from hemodynamic adaptations. Objective: To evaluate hemodynamic responses after traditional (TT) and eccentric (ET) training sessions in PP athletes. Methods: Twelve national-level PP athletes, aged: (Mean ± SD) 30.8 ± 10.05 years; 70.0 ± 16.1 kg. In the intervention, five sets of five repetitions (5 × 5) of the bench press at 80% of 1 repetition maximum (1RM) were used; in the TT and in the ET, 5 × 5 of the bench press with a load in the eccentric phase of 110% and that in the concentric phase of 80% of 1RM were used. Results: Compared to baseline, heart rate was significantly elevated at various times in the ET, between before and 20 min after (p = 0.023), and 40 min after (p = 0.035), but decreased to baseline in 24 h (p = 0.043, η2p = 0.395). In addition, the product pressure rate in the ET had a decrease between the moments before and 60 min after (p = 0.042), and before and 24 h after (p = 0.043). A high effect on myocardial oxygen volume in ET at 24 h was found (p = 0.018; η2p = 0.393). Conclusions: One session of traditional and eccentric training methods can be effective in causing significant changes in the cardiovascular system in PP athletes.
