Key result
Maximal bench press exercise promoted a moderate hypotensive effect with blood pressure adaptation up to 60 minutes post-exercise in both Paralympic and conventional powerlifters (SBP p<0.001).
Why the study?
High blood pressure is associated with several complications and causes of death, prompting the analysis of hemodynamic responses before and up to 60 minutes after training in Paralympic and conventional powerlifting.
Does maximal bench press exercise affect hemodynamic responses differently in Paralympic versus conventional powerlifting athletes?
Observational (n=20)
Does maximal bench press exercise affect hemodynamic responses differently in Paralympic versus conventional powerlifting athletes?
p-value: p=<0.001
Maximal bench press training promotes a moderate hypotensive effect without hemodynamic overload in both Paralympic and conventional powerlifting athletes.
May warrant post-exercise BP monitoring in powerlifters with hypertension; leaves open differential responses between Paralympic and conventional athletes.
High blood pressure (HBP) has been associated with several complications and causes of death. The objective of the study was to analyze the hemodynamic responses in Paralympic bench press powerlifting (PP) and conventional powerlifting (CP) before and after training and up to 60 minutes (min) after training. Ten PP and 10 CP athletes performed five sets of five repetition maximal bench press exercises, and we evaluated systolic, diastolic, and mean blood pressure (SBP, DBP, and MBP, respectively), heart rate (HR), heart pressure product (HPP), and myocardial oxygen volume (MVO2). The SBP increased after training (p < 0.001), and there were differences in the post training and 30, 40, and 60 min later (p = 0.021), between 10 and 40 min after training (p = 0.031, η2p = 0.570), and between CP and PP (p =0.028, η2p = 0.570). In the MBP, there were differences between before and after (p = 0.016) and 40 min later (p = 0.040, η2p = 0.309). In the HR, there was a difference between before and after, and 5 and 10 min later (p = 0.002), and between after and 10, 20, 30, 40, 50, and 60 min later (p < 0.001, η2p = 0.767). In HPP and MVO2, there were differences between before and after (p = 0.006), and between after and 5, 10, 20, 30, 40, 50, and 60 min later (p < 0.001, η2p = 0.816). In CP and PP, there is no risk of hemodynamic overload to athletes, considering the results of the HPP, and training promotes a moderate hypotensive effect, with blood pressure adaptation after and 60 min after exercise.

Aidar et al. (2021) conducted an observational in Healthy athletes (Paralympic and conventional powerlifting) (n=20). Maximal bench press exercise vs. Baseline (before training) and between groups (CP vs PP) was evaluated on Hemodynamic responses including systolic blood pressure (SBP) (p=<0.001). Maximal bench press exercise promoted a moderate hypotensive effect with blood pressure adaptation up to 60 minutes post-exercise in both Paralympic and conventional powerlifters (SBP p<0.001).
